How to Hide or remove a JLabel

I have declared a JLable as follows;

l = new JLabel("Hello");
l.setHorizontalAlignment(SwingConstants.CENTER);
panel.add(l);

Now, i want to hide or remove it. What should be the method i should call ?

i tried l.removeAll(); <--- nothing hapend.

there's another one calle remove(int) which takes an int. But i am not sure what to pass as the parameter.

There's also something called hide(). but it's deprecated.

You have to use the method getContentPane(). This way is possible to remove the element by the declaration name of the component.

private JFrame frame;
private JLabel label;
...

frame.getContentPane().remove(label);

I faced the same problem in my project.

You should make sure about removing previous controls and refreshing the panel.

see this snippet code :

panel.removeAll();  


panel.revalidate();

Hope This Helps U All The Best :)

you need to call to remove on JPanel which the JLabel was added to :

panel.remove(l);

//after that you need to call this to revalidate and repaint the panel
panel.revalidate(); 
panel.repaint();

just to hide and not to remove call

l.setVisible(false);

Try panel.remove(l);

panel.removeAll() should also work, but that also removes other components which may have been added to the pannel.

The javadoc of hide() tells setVisible() should be used instead. So try calling setVisible(false).
