private Label sampleString;
private Button showTheString;
private ButtonHandler bHandler;
private FlowLayout layout;
public StringApplet() {
sampleString = new Label(" ");
showTheString = new Button (" Show the String");
bHandler = new ButtonHandler();
layout = new FlowLayout();
showTheString.addActionListener(bHandler);
setLayout(layout);
add(sampleString);
add(showTheString);
}
class ButtonHandler implements ActionListener {
public void actionPerformed(ActionEvent e) {
samplestring.setText("Good Morning");
