public class AddApplet extends JApplet {
int sum;
int x;
int y;
public void init() {
String num1;
String num2;
// read first number from the keyboard
num1 = JOptionPane.showInputDialog("Enter a First number");
// read seond number from the ketboard
num2 = JOptionPane.showInputDialog("Enter a Second number");
x= Integer.parseInt(num1); // comvert the string to an integer
y= Integer.parseInt(num2); // convert the string to an integer
sum = x + y;
}
public void paint(Graphics g) {
//writes the output in the applet starting at position 30, 30
g.drawString("The sum of x ("+x+") +y ("+y+")="+sum, 30,30);

1)AppletSum.java:
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class AppletSum extends Applet implements ActionListener{
TextField text1,text2,output;
Label label1,label2,label3;
Button button;
public void init(){
setLayout(null);
label1 = new Label("Enter Number1: ");
label1.setBounds(20,20,100,20);
add(label1);
text1 = new TextField(5);
text1.setBounds(150,20,100,20);
add(text1);
label2 = new Label("Enter Number2: ");
label2.setBounds(20,50,100,20);
add(label2);
text2 = new TextField(5);
text2.setBounds(150,50,100,20);
add(text2);
label3 = new Label("Sum of Two Numbers: ");
label3.setBounds(20,80,130,20);
add(label3);
output = new TextField(5);
output.setBounds(150,80,100,20);
add(output);
button = new Button("Sum");
button.setBounds(150,110,100,20);
add(button);
button.addActionListener(this);
}
public void actionPerformed(ActionEvent ae){
int num1=Integer.parseInt(text1.getText());
int num2=Integer.parseInt(text2.getText());
int sum=num1+num2;
output.setText(Integer.toString(sum));
}
}
2)applet.html:
