After over 70 postings on the forum you should know how to use the "code formatting tags" so the code you post is formatted and readable.

You need to change the background of the content pane, not the JFrame.

Read the section from the Swing tutorial on Custom Painting for the proper way to do this. You should NOT override the paint() method.

As you said, i replaced my run method like:



now i m able to get my background color, but now my text

g.drawString("Hello it's me punit.", 200, 200);

is not visible.

1) Still didn't paste the code properly. I'm sure you don't write code left justified, so don't expect use to read it like that.

2) Can't tell what you are doing because you didn't post a proper SSCCE.

No no no no no. That was my first reaction when I saw your code. You are blocking the Event Dispatcher Thread with your sleep call, and that causes the entire user interface to block. Please read Concurrency in Swing.
