Re: CS506 Assignment 1 Solution and Discussion Please read the following instructions carefully before solving & submitting assignment: Uploading Instructions: • You are not allowed to use any IDE tool like NetBeans for this assignment. • Use Notepad or Notepad++ for coding and JDK package for Java source code compilation and running. • Place all the source code (.java & .class files) in a Zip/RAR file, save with your own Student ID (e.g. bc000000000.zip) and Upload it on VULMS within due date. • Your assignment should be in .zip /.rar format. Other file formats will not be accepted. • No assignment will be accepted through email. Rules for Marking: It should be clear that your assignment will not get any credit if: o The assignment is submitted after due date. o The submitted assignment does not open or file is corrupted. o The assignment is fully or partially copied from other student or ditto copy from handouts or Internet; strict disciplinary action will be taken in this case. o The assignment is not submitted in .zip /.rar format. Note: Do not put any query on MDB regarding this assignment, if you have any query then email at cs506@vu.edu.pk Lectures Covered: This assignment covers Lectures # 1 to 9 GOOD LUCK Problem Statement: You are required to develop a Java program named MyATM, which should simulate behavior of a typical ATM (Automated Teller Machine). In which a user, after entering card details, can deposit amount, withdraw cash and view current balance. The program should be based on a user friendly interface; need to use Java basic GUI component (i.e. JOptionPane) for this purpose. Further, all information must be saved in a backend database using simple text file. Detailed Description: At start, your program should ask the user to provide card number (e.g. vu-bsxxxxxxx) and pin code (e.g. 1234) as input. After taking input from user the program should fetch user data corresponding to the input from database (i.e. text file) and store in a global variable (e.g. debitCard). Taking input from user is shown in figure no 1. Fig. 1: Taking input from User If input values are correct (i.e. provided values are same as given in text file) then following ATM services should be displayed via GUI; Deposit Amount Withdraw Cash Check Balance Exit the Program However, in case, if input values are not correct (i.e. found no user against provided card number and pin code) then appropriate message should be shown, like; “Invalid Card No or wrong Pin Code”. Fig. 2: ATM Services GUI Deposit Amount: Each time, user selects this option, s/he will be prompted to enter money for deposit that must be in multiple of Rs. 500/- (hint is given below) and up to a maximum of Rs. 25000/- per transaction. If inputs are correct then the amount must be added in current balance and as well as in database. However, in case of wrong input, appropriate message should be displayed. [image: JyLYbJe.png] Fig. 3: Deposit Amount GUIs Withdraw Cash: User can withdraw any cash but in multiple of Rs. 500/- (hint is given below) and up to a maximum of Rs. 25000/- per transaction by using this option. However, if balance is zero or withdraw amount is greater than the balance, then appropriate message should be displayed. Otherwise, amount must be deducted from current balance and database should be maintained. [image: AsBo8D1.png] Fig. 4: Cash Withdraw GUIs Check Balance: The program should fascinate the user by displaying the current balance via GUI. [image: pwLOHEw.png] Fig. 5: Check Balance GUI Exit the Program: [image: O5TtLQa.png] Before exiting, the program should display the developer information (i.e. Student Id and name) via GUI. Fig. 6: Developer Info GUI Required Stuff: For this purpose, you have to create a text file and three separate Java classes, details are as follows; Text File: A simple text file, which should contain single line “vu-bsxxxxxxx,1234,0” in it and must be saved as bsxxxxxxx.txt. Here, “bsxxxxxxx” at both (i.e. file name and single line text) must be same as your own student id. And “vu-bsxxxxxxx” is card no, “1234” is pin code and “0” is initial balance. [image: ENvKGIe.png] Fig. 7: Sample Data in Database (.txt file) DebitCard.java: Data Members: • cardNo: String • pin: int • balance: long Constructors: • default, parameterized & copy constructor Standard Setters: • setCardNo(…), setPin(…) & setBalance(…) Standard Getters: • getCardNo(), getPin()& getBalance() DbHelper.java: Data Members: • FILE_NAME: String // static and final variable Member Functions: • loadData() & saveData(…) Main Class: Data Members: • debitCard: DebitCard • dbHelper: DbHelper Constructor: • default Member Functions: • main(…), initLoginGUI(), initServicesGUI(), depositAmoount(), cashWithdraw(), checkBalance() & showDeveloperInfo() Hint: if (amount % 500 == 0) { // it is a multiple of 500. } Video Tutorials:  To download & install JDK and create a HellowWorld program in Java, please watch; https://www.youtube.com/watch?v=AyANioRrpD0  To download JDK setup file for Windows x64 from VU-LMS, please visit; Important Things to Implement:  You have to provide Java classes in separate .java files as guided above. Merging of two or more will result in deduction of marks.  Each Java class must have proper Data Members and Member Functions along with Constructors, Standard Setters and Getters etc. as discussed above.  For GUI, you have to use JOptionPane.showInputDialog and JOptionPane.showMessageDialog for taking input from user and showing output to user respectively.  Need to make sure that exceptions are managed properly throughout the program; especially NullPointerException and NumberFormatException while taking input from user.  All images and sample data, given in this document, are just for reference purpose only; you have to provide your own implementations. It is not required to be exactly the same. Good Luck

Re: CS506 Gdb1 Solution and discussion GDB Topic: In general, a typical Java program is dealt with the following kinds of thread: Main Thread; initial application code is executed. Worker Thread; time-consuming and background tasks are executed. Well, Java based smart devices (embedding Java code in smart devices) have revolutionaries the human life. At one side, these devices provide ease of use of technology. But on the other side, their unresponsiveness or delay in response to user’s actions may result in human frustration. One of the main reasons is, these devices mostly run on a single Main Thread. Being a Java developer what do you think, “Use of Worker Threads along with Main Thread will reduce the response delay or increase the work load in Java based Smart Devices?”

Note: Do not put any query on MDB regarding this assignment, if you have any query then email at cs506@vu.edu.pk Lectures Covered: This assignment covers Lecture # 1-17 GOOD LUCK Problem Statement: You are required to write a Java program, named ShoppingCart, for a typical online shopping system. In which a customer can add and remove items to the shopping cart. The program will calculate the total bill as the items are added/removed to/from shopping cart and will display the amount via user friendly Interface on real time basis. Further, all orders will be saved in a backend database using MS Access so that the administrator could process the orders properly. Detailed Description: At start, your program should read Products Data from MS Access database file (sample data is given below) and display a GUI (i.e. Graphical User Interface) which should contain options for selecting quantity of products, sample is given below; [image: SXBz5T9.png] Fig. 1: Shopping Cart GUI Here, the customer can select the quantity (i.e. 0 to 10) for available products by clicking on add (+) or remove (–) buttons; the cart should be updated on each action and correct amount after calculating the number of items, subtotal, shipping charges (shipping charges are given below) and grand total should be displayed. When user clicks on “Place Order” then the program should check whether the cart contains any item or not. If cart is empty then a message “Cart is empty!” should be displayed. Otherwise, order details will be saved to MS Access database file and interface will be updated with initial values (i.e. zero quantity for each item and zero in amount fields etc.) as well. Further, cross icon at top right corner of the interface should terminate the program and show the developer information (i.e. Student Id and name) via message dialog. [image: sWyqLUY.png] Fig. 2: Developer Info Required Stuff: Java Classes: Product.java Cart.java DatabaseHelper.java (should contain all database related code) MainClass.java (should contain GUI code) Database file: BSxxxxxxxx.accdb (must be same as your own VU student id) Note: need to put database file in assets folder in NetBeans project directory; as shown below; [image: MIuLFm4.png] Fig. 3: Folder “assets” in NetBeans project directory Sample Data: Item Price ($) 1 Orange 2.0 2 Grapes 2.5 3 Banana 1.5 4 Mango 3.0 Tab. 1: Sample Products Data No of Items Charges 1 0 $0 2 1 to 5 $0.5 3 6 to 10 $1.0 4 11 to 15 $1.5 5 16 to 20 $2.0 6 21 to 25 $2.5 7 26 to 30 $3.0 8 31 to 35 $3.5 9 More than 35 $4.0 Tab. 2: Sample Shipping Charges [image: DFkeM2b.png] Tab. 3: Products Table in MS Access Database file [image: RokU8Vy.png] Tab. 4: Orders Table in MS Access Database file Important Things to Implement:  For GUI, relevant components (i.e. JFrame, JPanel, JButton, JTextField and JLable etc.) from AWT and Swing packages should be used.  You will have to use ucanaccess driver to connect to MS Access database.

Note: Do not put any query on MDB regarding this assignment, if you have any query then email at cs506@vu.edu.pk Lectures Covered: This assignment covers Lecture # 1 - 30 GOOD LUCK   Problem Statement: You are required to deploy a basic web application using Apache Tomcat Server, named ShoppingCart, for a typical online shopping system. In which a customer can add/remove items to shopping cart and proceed to place order. The program should calculate total bill and display amount via web page. Further, all orders will be saved in a backend database using MS Access so that administrator could process accordingly. [floatRight]Detailed Description: The program should facilitate at least one user i.e. Customer. For this purpose, you have to develop an html page (index.html) which should contain a login form, as shown in figure 1. [image: Vlpr8yW.png][/floatRight] The customer should be able to login by using student id (must be your own student id) as username and “vu” as password. Now, write a Java Servlet named as LoginServlet.java that will receive submitted information from login form (i.e. index.html) and verify input values; whether entered values are correct or not. If authentication is invalid then print back a message “Invalid Username or Password”. If customer credentials (i.e. username and password) are correct, jump to Shopping Cart Page (i.e. ShoppingCartServlet.java) which should list down all available products (i.e. products having one or more items), as shown in figure 2. [image: gAuXrL7.png] Here, customer can provide quantity of desired product/s and click on Check Out button. If no item is selected (i.e. no quantity is provided), then a message “Cart is empty” should be displayed. On the other hand, if cart is not empty, Checkout Page (i.e. CheckOutServlet.java) should serve the customer by displaying total bill, shipping charges along with no. of products & items etc. and also provide an input field for shipping address, as shown in figure 3. [image: UPKP78K.png] To place order, customer must provide shipping address and click on Place Order button. Before displaying message "Order has been placed successfully.”, the program must save order details (i.e. no. of items, subtotal, shipping charges, grand total, shipping address and selected products with quantity) in corresponding database tables. Further, need to maintain quantity of products in database so that customer could not see out of stock products in next shopping. Button “Go Back” should take back on Shopping Cart Page. However, customer can sign out from system by pressing “Logout” button. In this case, web developer information (student id, name and email address) should be displayed via an HTML page (info.html), as shown in figure 4. [image: sx2DRhQ.png] Required Stuff: Html Pages: index.html info.html Java Servlets: LoginServlet.java ShoppingCartServlet.java CheckOutServlet.java Java Classes: Product.java Cart.java Order.java OrderDetail.java DatabaseHelper.java (must contain all database related code) Database file: BSxxxxxxxx.accdb (must be same as your own VU student id) Shipping Charges: Shipping Charges ($) = ((no. of Items / 5) + 1) * 0.5 Sample Data & Database Tables: Tab. 1: Sample Products Data # Name Price Quantity 1 Flour $18.00 20 2 Oil $19.00 50 3 Ghee $10.00 0 4 Sauce $22.00 40 5 Sugar $21.35 35 6 Salt $25.00 26 7 Daal $30.00 38 8 Rice $40.00 92 9 Pasta $97.00 63 10 Fruits $35.00 72 11 Dry Fruits $31.00 70 12 Tea $21.00 12 13 Coffee $38.00 9 14 Milk $10.00 10 15 Snacks $23.25 13 16 Dessert $15.50 22 17 Vegetables $17.45 52 18 Chicken $39.00 98 19 Beef $62.50 0 20 Frozen Food $19.20 30 21 Sea Food $81.00 29 22 Sweet $10.00 29 23 Cake $21.00 0 24 Yogurt $26.00 0 25 Pickle $30.00 41 Tab. 2: Products Table in MS Access Database [image: 7i9OFP4.png] Tab. 3: Orders Table in MS Access Database [image: Pf9ldDs.png] Tab. 4: Order Details Table in MS Access Database [image: enC3m6e.png] Video Tutorials: To download and install of Tomcat Server, please watch; https://youtu.be/eaYAcv3p9Vw  To create a web application project in NetBeans IDE, please watch; https://youtu.be/S9LGRuILHfc  To add ucanaccess driver in a NetBeans project, please watch; https://youtu.be/G8iUNPz1c6s Important Things to Implement:  You have to provide separate pages, servlets, java files and database tables as guided above.

GDB: IoT (Internet of Things) has opened up a world of possibilities in patient monitoring systems. The smart device like Pacemaker continuously monitors patient’s heart, generates electric pulses to prevent heart rate from going too slow and inform the physician about the health on real time basis. Hence smart devices can save lives in emergency cases as well. But what makes these devices “smart”, when they are having several barriers like limited memory, slow processing speed, connectivity issues and security concerns etc. Are they really smart enough? Being a Java developer what do you think, “Embedding Java programs in IoT devices, will make them smart or result in bad performance, for health care systems?” Instructions: Your comment must not be more than 4-5 lines and that must be concise, coherent and to the point comment. GDB will not get any grade If comment is lengthy and irrelevant. If found copied from other student or from internet material. If GDB solution is posted via mail within or after due date.

      To determine which of the following is not a web technology related to Java, I would need a list of options. However, here are some common Java web technologies and tools, which might help:

      Common Java Web Technologies:

      1. Servlets: A technology for creating web applications in Java.
      2. JSP (JavaServer Pages): A technology that allows you to embed Java code in HTML pages.
      3. JSF (JavaServer Faces): A Java web framework for building user interfaces.
      4. Spring MVC: Part of the Spring Framework, used to create web applications.
      5. Hibernate: An ORM (Object-Relational Mapping) framework, but not strictly a web technology.
      6. JAX-RS (Java API for RESTful Web Services): A Java API for building RESTful web services.
      7. Struts: An open-source web application framework used to develop Java EE web applications.
      8. GWT (Google Web Toolkit): A development toolkit to build and optimize complex browser-based applications.
      9. Thymeleaf: A server-side Java template engine for web and standalone environments.

      Non-Java Web Technologies:

      Here are some technologies that are not specific to Java:

      • PHP: A server-side scripting language used for web development.
      • Ruby on Rails: A web application framework written in Ruby.
      • ASP.NET: A web framework developed by Microsoft for building dynamic web applications.
      • Django: A high-level Python web framework.
      • JavaScript: A programming language primarily used for front-end web development.

      If you have specific options, please provide them, and I can identify which is not a Java web technology.

        @zareen said in CS506 MCQ's Final Term Paper:

        Which of the following object contains information specific to a servlet?
        Select correct option:
        ServletContext
        ServletConfig
        ServletRequest
        ServletResponse

        The object that contains information specific to a servlet is ServletConfig.

        Here’s a brief explanation of each option:

        • ServletContext: This object provides information about the servlet’s environment and context, such as attributes and parameters that are common to all servlets in the application. It does not contain servlet-specific information.

        • ServletConfig: This object contains information specific to a servlet, including initialization parameters and references to the ServletContext. It is created by the servlet container and is unique to each servlet.

        • ServletRequest: This object represents the client’s request and contains information such as request parameters, attributes, and the HTTP method. It is used to handle the request but does not store servlet-specific information.

        • ServletResponse: This object represents the response that will be sent to the client and is used to provide data back to the client. It is concerned with the output of the servlet, not its configuration.

        So, the correct option is ServletConfig.

          @zareen said in CS506 MCQ's Final Term Paper:

          Which of the following is/are not correct about Thread(s)?
          Select correct option:
          Light weight
          Heavy weight
          Share same memory
          Light weight and share same memory

          The correct option is:

          Heavy weight

          Threads are generally considered to be lightweight compared to processes because they share the same memory space (i.e., address space) and resources within a process. Threads within the same process can efficiently share data and communicate with each other due to this shared memory.

          Therefore, threads are not heavy weight; they are lightweight and share the same memory.
