In this tutorial how to handle event in Applet along with Graphics in Core Java is shown.<\/p>\n
Code:<\/p>\n
MyAppletEven.java<\/p>\n
\/* <applet code=”MyAppletEven” height=”400″ width=”400″> <\/applet>*\/<\/p>\n
import java.awt.*;
\nimport java.awt.event.*;
\nimport java.applet.*;
\nimport javax.swing.*;<\/p>\n
public class MyAppletEven extends Applet
\n{
\nint no;
\nString flag;
\nButton b;
\nLabel l;
\nTextField t;<\/p>\n
public void init()
\n{
\nb = new Button(“OK”);
\nl = new Label(“Enter a number:”);
\nt = new TextField(30);<\/p>\n
add(l);add(t);add(b);<\/p>\n
b.addActionListener(new ActionListener()
\n{
\npublic void actionPerformed(ActionEvent e)
\n{
\nno=Integer.parseInt(t.getText());<\/p>\n
if(no%2==0)
\n{
\nflag=”green”;
\nrepaint();
\n}
\nelse
\n{
\nflag=”red”;
\nrepaint();
\n}
\n}
\n});
\n}<\/p>\n
public void paint(Graphics g)
\n{
\nif(flag.equals(“green”))
\n{
\ng.setColor(Color.green);
\ng.drawString(“No: “+no,100,200);
\n}
\nelse
\n{
