Develop an applet that receives an integer in one text field when the button named

**Aim: TO Develop an applet that receives an integer in one text field, and computes its factorial value and returns it in another text field, when the button named ―Compute is clicked**

**Source
Code:**

import java.applet.*;

import java.awt.*;

import java.awt.event.*;

class actlstn implements ActionListener

{

public void actionPerformed(ActionEvent e)

{

int ctr=1,no=0,fact=1;

Button bt;

bt=(Button)e.getSource();

if((bt.getLabel()).equals(“compute”))

{

no=Integer.parseInt(appltfact.t1.getText());

while(ctr<=no)

{

fact*=ctr;

ctr++;

}

t2.setText(String.valueOf(fact));

}

System.out.println(“….”);

}

}

public class appltfact extends Applet

{

static TextField t1,t2;

Label l1,l2;

Button b;

public void init()

{

l1=new Label(“enter an integer.”);

l2=new Label(“fatorial val:”);

t1=new TextField();

t2=new TextField(” “);

b=new Button(“compute”);

add(l1);

add(t1);

add(l2);

add(t2);

b.addActionListener(new actlsn());

add(b);

setSize(300,400);

setVisible(true);

}

public void paint(Graphics g)

{

showStatus(“computing Factorial value…”);

}

}

Expected Output:

Develop an applet that receives an integer in one text field when the button named
