java.applet.AppletContext class provides the facility of communication between applets. We provide the name of applet through the HTML file. It provides getApplet() method that returns the object of Applet. Syntax:
- public Applet getApplet(String name){}
Example of Applet Communication
- import java.applet.*;
- import java.awt.*;
- import java.awt.event.*;
- public class ContextApplet extends Applet implements ActionListener{
- Button b;
- public void init(){
- b=new Button(“Click”);
- b.setBounds(50,50,60,50);
- add(b);
- b.addActionListener(this);
- }
- public void actionPerformed(ActionEvent e){
- AppletContext ctx=getAppletContext();
- Applet a=ctx.getApplet(“app2”);
- a.setBackground(Color.yellow);
- }
- }
