Q1. Engr. Sarim is supposed to computerize food management system for Pizzoa, a new food venture opened in Karachi. Sarim is working as a senior software developer in a renowned organization. Requirements of Pizzoa for a system are as follows which are collected:  A system should be menu driven, at the time of execution program should display following menu. o Press 1 for Display menu. o Press 2 for add item in menu. o Press 3 to delete item from menu o Press 4 to exit. CODING: 1. Create a class for pizzoa , add required attributes where one attribute is Manager_name. Write methods for add item, delete item, and display menu. Hint: you can use array list for menu items. 2. Create application class where you have to create an object of pizzoa class. 3. Assign manager name as your name from application class using object reference. 4. Write a code to display above mentioned menu in application class. 5. Take user input for desired choice of button and using conditional statements (ifelse/switch case) call appropriate methods of pizzoa class. 6. On pressing 4 application program should stop running. Hint: use exit() REQUIRED OUTPUT 1. Run the program and add 10 food items of your choice in menu, and then display menu. 2. Delete any 2 items of your choice and then display menu.

Q2. Consider that you need to develop a software for PWF School. Requirements from client (PWF school representative) is to have a software that saves the information of all the students and have the facility of fees payment as well. Student’s name, class, address, ID and contact are the basic components of information that needs to be stored in a system. User will be able to enter all these information in a system, and also can enter the fees and see the updated status as well. Fee structure is given below for all the classes. Class I,II, III IV, V VI,VII,VIII IX, X

Monthly Fees 2500/3000/3500/5000/-

1. Construct a class for Student, mention all its attribute as private. 2. Write getter setter methods to set and get the values of all the attributes. 3. Write the code for parameterized and non-parameterized constructors as well for the student class. 4. Develop a method of Feepayment, which ask from user to enter fee amount and class and matches from the data given in above table if user paid correct amount or not. If excess amount is paid then a message will be shown that this amount is returned to the user and if less amount is paid then message will be shown that “Enter full amount”. 5. Develop a method of Fee status as well. Which shows the Fee status as paid or not paid. 6. Develop a method Showinfo( ) that shows the student name,class, ID and fee status. 7. Develop an application class and create 5 objects of student. Enter data for all 5 students and pay their fees as well (use various amount inputs), and call showinfo() method for all 5 students.
