Applet to add numbers using TextField

In this applet, we can add two numbers using GUI, where we take input from the user through text fields.

import java.applet.*;//Importing java.applet

public class MyApplet extends Applet

{

TextField txt1, txt2;

public void init()//Initializing our applet

{

txt1 = new TextField(""); //Creates a textfield 'txt1'

txt2 = new TextField(""); //Creates a textfield 'txt2'

setBackground(Color.CYAN);//Setting background color to CYAN

add(txt1); //Adds textfield 'txt1' to your applet

add(txt2); //Adds textfield 'txt2' to your applet

}

public void paint(Graphics obj)//Paint method to display our message

{

String s1 = txt1.getText(); //Fetching data from text field 1.

String s2 = txt2.getText(); //Fetching data from text field 2.

int num1=0, num2 = 0, num3; //Declaring 3 integer variables

num1 = Integer.parseInt(s1); //Parsing the string value of text field 1 to integer

num2 = Integer.parseInt(s2); //Parsing the string value of text field 2 in integer

num3 = num1 + num2; //Performing addition

String s3 = String.valueOf(num3); //Converting the result from integer to string

obj.drawString("Result:", 40, 50);

obj.drawString(s3, 50, 50);//To display the result

}
