image the URL specifies the destination of a image from which image has to be loaded

add(l1);
jb.addActionListener(this);
jb.setActionCommand("BUTTON 1");
}
public void actionPerformed(ActionEvent ae){

{
int getfile;
open = new JFileChooser();
int option = open.showOpenDialog(this);
if (option == JFileChooser.APPROVE_OPTION) {
l1.setIcon(new ImageIcon(open.getSelectedFile().getPath()));
