Question
please i want this answer for java j2sdk1.4.1 it is a project for university so please make sure it is for java j2sdk1.4.1 thank you in advance and in university we use the SavitchInDesign and implement the following two classes:
1. A class personType contains the following protected data members:
a. Person firstName
b. Person lastName
personType class contains the following methods: constructors, set, get and print
2. A class customerType contains the following private data members:
a. studentId
b. list for cars rented (array of strings)
c. maxsize of the list of cars (default equal 10)
d. ncars of cars rented
customerType class contains the following methods:
• Constructor
• set (to set the student firstName, lastName, customerId, and cars rented)
• return a car
• print ( to output the customer name, customerId, and cars rented)
• writeToFile(to print the id’s and names of the customers to a file)
Notice that customerType calss inherits the name of the personType calss and that the set and print methods of customerType class will have to call the set and the print of the personType class.
3. A class carType that keeps records of the available and rented cars, it has:
a. carId
b. carType
c. status(available/not available)
CarType class contains the following methods:
a. constructor
b. setInfo
c. getId, getType, getStatus
d. rentCar
e. returnCar
Write a main Method to declare a dynamic array of customerType objects and a dynamic array of carType objects and then display a menu to the user to choose any possible operation for as many times as he/she wants.
