I want to call a method of one
applet(AppA) in another applet(AppB)but on
Java Console it is giving null pointer exception. Following is code.
import java.applet.*;
import java.awt.*;
public class AppA extends Applet
{
Button b1;
public void init()
{
b1=new Button("A");
add(b1);
}
public
String say()
{
return "hello";
}
}
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
public class AppB extends Applet implements ActionListener
{
Button b1;
TextField t1;
public void init()
{
b1=new Button("Click");
b1.addActionListener(this);
t1=new TextField(10);
add(b1);
add(t1);
}
public void actionPerformed(ActionEvent e)
{
AppA r=(AppA)getAppletContext().getApplet("AppA");
t1.setText(r.say());
}
}
