Question

In one file create an Employee class as per the following specifications:

1. three private instance variables: name (String), startingSalary (int), yearlyIncrement (int)

2. a single constructor with three arguments: the name, the starting salary, and the yearly increment. In the constructor, initialize the instance variables with the provided values.

3. get and set methods for each of the instance variables.

4. A computation method, computeCurrentSalary, that takes the number of years in service as its argument. The method returns the current salary using the calculation: startingSalary + years * yearlyIncrement

In a separate file, create a driver as follows:

• In the main method, create two Employee objects: Alice with a starting salary of 50000 and a yearly increment of 1000 and Bob with a starting salary of 40000 and a yearly increment of 2500. Write a loop to display the current salaries of the two employees at the end of years 1 through 10. A sample output is shown below.

Answer 1

Here is the code for the above assignment.

Feel free to comment on any doubt and give thumbs up!

There are 2 files that contain the code.

1. Employee.java which contains the Employee class with all the necessary members

2. Driver.java which contains the main method.

Code for Employee.java

class Employee

{

// Private data members

private String name;

private int startingSalary;

private int yearlyIncrement;

// constructor

public Employee(String name, int startingSalary, int yearlyIncrement)

{

this.name = name;

this.startingSalary = startingSalary;

this.yearlyIncrement = yearlyIncrement;

}

// setter method

public void setName(String name){

this.name = name;

}

public void setStartingSalary(int sal){

startingSalary = sal;

}

public void setYearlyIncrement(int inc){

this.yearlyIncrement = inc;

}

// getters

public String getName()

{

return name;

}

public int getStartingSalary(){

return startingSalary;

}

public int getYearlyIncement(){

return yearlyIncrement;

}

public int computeCurrentSalary(int years){

return startingSalary + (years * yearlyIncrement);

}

}

Code for Driver.java

public class Driver{

public static void main(String[] args) {

// creating objects

Employee alice = new Employee("Alice", 50000, 1000);

Employee bob = new Employee("Bob", 40000, 2500);

// loop to print salary.

for(int i = 0 ; i < 10 ; ++i){

System.out.println("Salary of Alice at the end of year " + (i+1) + " is " + alice.computeCurrentSalary(i+1));

System.out.println("Salary of Bob at the end of year " + (i+1) + " is " + bob.computeCurrentSalary(i+1));

}

}

}
