1. One way: change the background color of a JPanel using setBackground(...) and set that JPanel as the contentPane of the JFrame.

2. JFrame#setIconImage(...)

Yes you can. Did you search on the web?

        ImageIcon imageBack = new ImageIcon(image_goes_here);
        JLabel background = new JLabel(imageBack);
        background.setBounds(0, 0, imageBack.getIconWidth(), imageBack.getIconHeight());
	getLayeredPane().add(background, new Integer(Integer.MIN_VALUE));
        jPanel1.setOpaque(false);
        setContentPane(jPanel1);

how can i replace the java icon with my icon in a JFrame.
I am using NetBeans IDE.

pls tell me.

[Eranga]

What you mean by java icon. You can use any icon there.

Eranga, I think pranav13 is referring to the title bar icon. The answer to that is at #2, and shouldn't have anything to do with the choice of IDE :)

Ah, I'm confusing with his message title and the content of the message.

hey, sry i hv clubbed 2 questions n confused u.
i gt the solution from bruke`s suggestion.
Actually, i was trying to set the icon property of the form in properties window in NetBeans IDE. But it is not setting. Thats why i have written it manually using setIconImage().

Thanks for your suggestions!

[DarrylBurke]

Well there is also a property IconImage (and also IconImages) that can be set from the NetBeans property list. But looking at it, it's easier to just write the code yuorself :)

As in the case of many other features of the Visual Editor.

I think write code your self is the best. Even that the above code segment I've written on NetBeans.

Umm, I think you should post a fresh topic for that. And to have a chance of getting good responses, you need to follow the advice here:
