Salary Computation in Java

Compute Salary in Java

This is a sample java program that will compute your salary based on the basic formula
salary = (number of days work * rate per day) – deduction

You are going to input your rate per day, number of days work and deduction to compute the salary.
The program is written in console and gui (graphical user interface) using the swing.

Source code:

import javax.swing.*;
import java.text.*;
class ComputeSalaryGUI {
public static void main(String[] args) {
	
String cont="n";
do
{
double sss=150;
double ph=250;
double pagibig=190;	
double tax=350;	
double deduction;	

String  emp1name, emp1hours, emp1otime, emp1rate;
String  emp2name, emp2hours, emp2otime, emp2rate;	
String  emp3name, emp3hours, emp3otime, emp3rate;
