why is this simple app freezing processing?

hello p5 companions!
I'm testing the get pixels function, but I don't know why something really simple freezes processing everytime (v68 - mac os X)... any ideas?
void scheck(int cx, int cy, int cw, int ch)
{
for(int i=cx;i<=(cx+cw);i++) {
for(int j=cy;i<=(cy+ch);j++) {
color actual = get(i,j);
println(i+" "+j+" "+actual);
}
}
}
void setup() {
size(200,200);
}
void draw() {
scheck(1,2,3,4);
}
it's just an application to get the colors from a certain area...
what's wrong?
Thanks!

There's an i/j mix-up in your second for loop. Since i doesn't change once you enter the second loop, you never meet the stop condition.

DOH!
Sorry guys, I've been not sleeping for a few days...
dumbest-problem-post-ever award goes to me.
By the way, is there any keyboard shortcut to break the application and stop the infinite loop? I was force-quitting processing all the times.
