Write a program to calculate bonus for different departments using method overriding.

import java.util.*;
abstract class dept
{
    double bp;
    dept(double bpay)
    {   
        bp=bpay;
    }
    void disp()
    {
        System.out.println("basicpay="+bp);
    }
    abstract double bonus();
}
class sales extends dept
{
    sales(double bpay)
    {
        super(bpay);
    }
    public double bonus()
    {
        return(0.20*bp);
    }
}
class marketing extends dept
{
    marketing(double bpay)
    {
        super(bpay);
    }
    public double bonus()
    {
        return(0.30*bp);
    }
}
class hr extends dept
{
    hr(double bpay)
    {
        super(bpay);
    }
    public double bonus()
    {
        return(0.50*bp);
    }
}
class MethodOverload
{
    public static void main(String arg[])
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("enter basic pay");
        double bp=sc.nextDouble();
        sales s=new sales(bp);
        s.disp();
        System.out.println("bonus for sales dept=" +s.bonus());
        marketing m=new marketing(bp);
        m.disp();
        System.out.println("bonus for marketing dept=" +m.bonus());
        hr h=new hr(bp);
        h.disp();
        System.out.println("bonus for hr dept=" +h.bonus());
    }
}
