Answer / sriharsha gowda
public void actionPerformed(ActionEvent ae)
{
String str=ae.getActionCommand();
if(ae.getSource()==b1) setBackground(Color.yellow);
if(ae.getSource()==b2) setBackground(Color.blue);
if(ae.getSource()==b3) setBackground(Color.pink);
}
The above code can be used whenever we have different buttons and when any button is clicked its color changes accordingly
