There is a very nice article at Swing connection (javasoft) about painting in AWT and Swing.<br />
<br />
take a look at it.<br />
the best answer to your question is:<br />
you should never override paint() in Swing components - you should override paintComponent().<br />

<div class="content wysiwyg-content">
I've derived a class from JPanel, and I want to draw in it and keep its background black, not gray. Calling<br />
<br />
setBackground(Color.black)<wbr />;<br />
<br />
in the constructor works fine if I don't override paint(). But if I do override paint(), the background color disappears and I can't figure out how to just keep it around and draw over it. Short of simply drawing a big rectangle over the whole panel, what should I be doing to keep the background color?

Keeping the background when painting a JPanel

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
