So basically, I have a JFrame, which originally contains panel A. After a few interactions, I want to remove this panel and add a new panel, say B. The problem is B won't show up until I resize the window. I even trying calling repaint(), but it doesn't seem to help. Can anyone explain what's going on? and how to fix the problem?
Thanks

I believe calling the validate() method in the JFrame will fix this problem.

Yep. validate() tells a Top-level component to "readjust" the screen if it changes while setVisible() is true. For components like JPanel or JComponent, you use revalidate() for the same purpose.
