Hi Friend,

Try the following code:

import javax.swing.*;
class Salary 
{
    public int calculateTax(int gs){
        double ded=gs*0.05;
        System.out.println(ded);
        int taxx=(int)ded;
        return taxx;
    }
    public int calculateBonus(String status,int hrs){
        int bonus=0;
        if(status.equals("Senior")){
            if(hrs>8){
                int hr=hrs-8;
                bonus=hr*50;
                return bonus;
            }
        }
        else if(status.equals("junior")){
                 if(hrs>8){
                int hr=hrs-8;
                bonus=hr*20;
                return bonus; 
                 }
        }
        return bonus;
    }
    public int calculateNetSalary(int gs,int hrs,String status){
        int tax=calculateTax(gs);
        int bonus=calculateBonus(status,hrs);
        int sal=bonus+gs;
        int netSalary=sal-tax;
        return netSalary;
    }
}
public class SalDemo{
    public static void main(String[]args){
Salary cal=new Salary();
String status=JOptionPane.showInputDialog(null,"Enter status Senior/Junior");
String st=JOptionPane.showInputDialog(null,"Enter number of hours");
int time=Integer.parseInt(st);
String salary=JOptionPane.showInputDialog(null,"Enter Gross Salary");
int grossSalary=Integer.parseInt(salary);
int net=cal.calculateNetSalary(grossSalary,time,status);
JOptionPane.showMessageDialog(null,"Net Salary is: "+Integer.toString(net));
    }
}

In the above code, we have create a condition if the time exceed 8 hours then there will be bonus otherwise not.As you have not specified the number of regular hours.

Thanks
