swing - JPanel Padding in Java -

I have a formatting question for my Java swing application, it should be quite simple, but I have difficulty finding a support (Every topic seems to be removed about any default padding in JPNL). In my various JPNs, the text embraces the touching colors of the sides and the top: How can I add padding? Your JPanel

set a empty border

Code>. Example:

  JPN P = new zpn (); P.setBorder (new blank border (10, 10, 10, 10));
