I need to write a small payroll program, using applet, that provides a text field for the number of hours, a text field for the pay rate, and a non-editable text field for the output. It should also also provide labels to identify all three text fields and a button to calculate the result.
Thanks
Thanks

Hi Friend,
Try the following code:
1)
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class OpenWindow extends Applet implements ActionListener {
Label l1,l2,l3;
TextField t1,t2,t3;
Button b;
Panel p;
public void init(){
l1=new Label("Number of hours");
l2=new Label("Pay Rate");
l3=new Label("Total");
t1=new TextField(20);
t2=new TextField(20);
t3=new TextField(20);
p=new Panel(new GridLayout(4,2));
t3.setEditable(false);
b = new Button("Calculate");
b.addActionListener(this);
p.add(l1);
p.add(t1);
p.add(l2);
p.add(t2);
p.add(l3);
p.add(t3);
p.add(b);
add(p);
}
public void actionPerformed(ActionEvent e){
int hours=Integer.parseInt(t1.getText());
int rate=Integer.parseInt(t2.getText());
int total=hours*rate;
t3.setText(Integer.toString(total));
}
}
2)applet.html:
<html>
<body>
<h1>Java Applet Demo</h1>
<applet code=OpenWindow .class width=500 height=400>
</applet>
</body>
</html>
Thanks
