i'm coding game , i'm trying have if click on first button on front page, shows transition screen 5 seconds, , shows game. here code:

however, right it's waiting 5 seconds, drawing transition screen , game. reason out of order.
how can fix this? have tried alternate methods of waiting 5 seconds, example using currenttimemillis();, have same outcome.
you have serious problems:
- you add panels twice
- you have circuitous use of frame etc
beyond following work: have realize don't have control of painting process. therefore should launch new thread count sleep , let paint work uninhibited.
(also have removed static - if want them can try put them in - if doesnt work throw them out)
