The things i put in "paint()" dont appear right away

Question

https://code.sololearn.com/cDG0IJ2PUs44/?ref=app

this is the code, when i run it in eclipse i get no errors or anything, but as you can see this code is supposed to paint a square on top of a black background, but instead it just paints a black background. in order for the square to appear i either need to put the window on fullscreen, resize it, or grab the window and shake it violently around in my computer screen. can someone help me fix this, or is it not my fault that this happens?

Answer 1

The GUI libraries that you are using are not supported by SL.

Answer 2

ohhhhhhhhhhhhhhh, yeah this code is not for solo learn
i was just hoping some1 knew what i did wrong

Answer 3

neither of these things worked, but i think ill just finish my project as an applet for now instead

Answer 4

ps. im not done with this code, i will eventually make the square move and shoot things, which is why i implemented keylistener

Answer 5

i left out one very important detail, im a noob and dont know what SL is

Answer 6
