Make a button a link?

public void init() {

t = new TextField(20);

t.setText("http://www.google.com");

add(t);

b = new Button("Go to this URL");

add(b);

b.addActionListener(this);

}

...

public void actionPerformed(ActionEvent ae) {

if (ae.getSource() == b) {

try {

getAppletContext().showDocument(new URL(t.getText()));

}

catch (Exception e) {

e.printStackTrace();

}

}

}

Then you made a mistake.

Here the complete example

import java.applet.*;

import java.awt.*;

import java.awt.event.*;

import java.net.*;

public class GotoURLButton extends Applet implements

ActionListener {

Button b;

TextField t;

public void init() {

t = new TextField(20);

t.setText("http://www.google.com");

add(t);

b = new Button("Go to this URL");

add(b);

b.addActionListener(this);

}

public void actionPerformed(ActionEvent ae) {

if (ae.getSource() == b) {

try {

getAppletContext().showDocument(new URL(t.getText()));

}

catch (Exception e) {

e.printStackTrace();

}

}

}

}

As is, the web page will replace the current one. To open a new window, change

getAppletContext().showDocument(new URL(t.getText()));

to

getAppletContext().showDocument(new URL(t.getText()),"_blank");
