No the button cannot act as an event handler.
button is a component, it generates an event and a listener handel this event.
please look at Events and Listeners.

Dear smitha
try this code:code:
import java.awt.*; import java.awt.event.*; class ButtonTest implements ActionListener { Button blueButton; Button yellowButton; public ButtonTest () { blueButton = new Button ("Blue"); yellowButton = new Button ("Yellow"); yellowButton.addActionListener (this); Frame f = new Frame ("Frame Test"); f.setLayout (new FlowLayout ()); f.add (yellowButton); f.add (blueButton); f.setSize (400, 300); f.setVisible (true); } //=========================== public static void main (String arg[]) { new ButtonTest (); } //============================= public void actionPerformed (ActionEvent ae) { if (ae.getSource () == yellowButton) blueButton.setLabel ("Not blue now"); } }

i have a choice button and a JTextField in a GUI. When an item in the choice is selected, it is meant to appear in the textfield but doesn't.
Here is my code :
JTextField tfPDPNo = new JTextField(); Choice chPDPNo = new Choice(); chPDPNo.addItemListener(new java.awt.event.ItemListener() { public void itemStateChanged(ItemEvent e) { chPDPNo_itemStateChanged(e); } }); void chPDPNo_itemStateChanged(ItemEvent e) { tfPDPNo.setText(chPDPNo.getSelectedItem()); System.out.println(chPDPNo.getSelectedItem()); }
As far as i can tell my code is correct. This is very confusing
