Employee.java

//Q8. The employee list for a company contains employee code, name, designation and basic pay. The employee is given HRA of 10% of the basic and DA of 45% of the basic pay. The total pay of the employee is calculated as Basic pay+HRA+ DA. Write a class to define the details of the employee. Write a constructor to assign the required initial values. Add a method to calculate HRA, DA and Total pay and print them out. Write another class with a main method. Create objects for three different employees and calculate the HRA, DA and total pay.

public class Employee {
    private String empCode;
    private String name;
    private String designation;
    private double basicPay;

    public Employee(String empCode, String name, String designation, double basicPay) {

        this.name = name;
        this.designation = designation;
        this.basicPay = basicPay;
