//create container
Container c = getContentPane();
//set a layout for container
c.setLayout(new FlowLayout());

//store the image into ImageIcon object
ImageIcon ii = new ImageIcon("car.jpg");

//create the button with the image

b.setToolTipText("This is a button");
//set a short cut key for button. Alt+C from keyboard will invoke
  //the button
b.setMnemonic('C');
//add the button to the container

//close the frame upon clicking
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String args[])
{
//create a frame
ButtonDemo obj = new ButtonDemo();
obj.setTitle("My Button");
obj.setSize(500,400);
obj.setVisible(true);
