Design and implement a class Employee in a java file called

Design and implement a class Employee in a java file called Employee.java. The class should contain instance variables for employee’s name, age, yearsOfService.

• Define the Employee constructor to accept and initialize instance data. The class should also keep track of the number of employee objects created using a static variable. This variable gets incremented every time in the constructor. • Include get and set methods for the three instance variables.

• Include a instance method called isEligibleForRetirement() that returns a boolean.

• true if the employee is eligible for retirement, false if not.

• For an employee to be eligible for retirement, the sum of age and years of service needs to be greater than 60.

• Create a client class called EmployeeApp (in a file called EmployeeApp.java) which has a main method.

• Using Scanner class, it will ask the user for data for 2 employees.

• i.e. name, age, and years of service for emp 1 and then emp 2.

• Take this user input and invoke the constructor of Employee class, passing the user provided input as arguments. You now have 2 initialized Employee instances.

• Now, your main method should print the number of Employee objects created, display data for each, and specify whether each employee is eligible for retirement or not

OUTPUT:

Enter the employee name:Srinivas
Enter the employee age:45
Enter the employee Years of Service:16
Enter the employee name:Pavan
Enter the employee age:40
Enter the employee Years of Service:18
Employee 1:Employee [name=Srinivas, age=45, yearsOfService=16]
Employee 2:Employee [name=Pavan, age=40, yearsOfService=18]
Employee 1 is eligible for Retirment.
Employee 2 is not eligible for Retirment.
Number of Employees :2
