Java Running Loop

Question

I want to learn how to run a loop without waiting the inner loop to finish looping.

cuz i have a 2 rect inside jpanel, then i also have 2 Jbutton

1 button will loop the rect1 and move from left to right every 1 px,
then i click the button 2 but the rect 2 doesnt move at all, it just waits for the rect1 to reach the right portion of the jpanel. I think its the loop

what i wanted to happen is that i can click rect 1 and start animating going to the right and i also can move rect2 to the right without waiting for rect 1 to finish moving

how can i do that?

Answer 1

What would be the expected behavior of your program, if the outer loop executes in parallel to the inner loop... ? E.g.

for (int i = 0; i < 10; i++)
for (int j = 0; j < 10; j++)
System.out.print(j);

Do you just want two loops which can execute in parallel, instead of nested loops? Multithreading, with each loop in different threads, so that two loops execute together?
