Drawing background in Java

Question

Hi, guys! I’m now learning how to create pictures in Java and feeling a little confused about backgrounds. Can anyone advise me some method to fill background with a color??

Answer 1

I found this at https://stackoverflow.com/questions/4219919/how-to-change-the-background-color-on-a-java-panel

You could call:

getContentPane().setBackground(Color.black);

Or add a JPanel to the JFrame your using. Then add your components to the JPanel. This will allow you to call

setBackground(Color.black);

on the JPanel to set the background color

Answer 2

Ok. For Java documentation https://docs.oracle.com/javase/7/docs/api/

Answer 3

Wallace Tomason, thank you for the answer! JPanel is already added to the JFrame, so I think setBackground will work. Actually I want to try set gradient as the background :)

Answer 4

Ok, thank you!
