Stuck on looping/flow control example

[Mike Cunningham]

I'm trying to determine when the variables are incremented in the following example....I'm stuck on this one.
for (int x = 0; x < 2; x++) {
for (int y = 0; y < 3; y++) {
if (x == y) {
continue;
}
System.out.println("x = " + x + " y = " + y);
}
}
Any help that would explain how this example works and when the variables are incremented will be a big help since I'm studying for SCJP.
Thanks in advance.

Mike...
Whenever x==y there wont be printout
So that means only
01
02
10
12
will be printed out
Whenever you see continue, immediately go back to the loop (incrementer ie i++) again...(as a human compiler i mean )

This is how it works.
1.first time x=0 and y=0,so it checks condition x==y,it is true so it continues with the inner loop incrementing y.
2.now x=0,y=1,now the test case is false and it prints out the value of x and y i.e 0 and 1.
3.Again y is incremented,so x=0 and y=2,test case is false and prints the value of x=0 and y=2.
4.Now the inner loop is completed as test condition is y<3,so now it continues with the outer loop so now x=1 and y=0 and it prints this value.
5.now the inner y loop is incremented i.e for x=1 and y=1 ,test case is true so it continues with the inner loop.
6.now x=1,y=2 and it prints the value.so now both inner and outer loop are completed.
7.the valued printed are x=0,y=1
x=0,y=2
x=1,y=0
x=1,y=2

Why does the 'y' variable get reset to '0' when it completes the first cycle of the inner loop?
Also, doesn't the increment value at the end of a for statement take place before the code is processed inside the loop? It seems like the first time through the x & y values should be '1'?

==========
y gets reset to 0 every time it enters the loop again.
also for every initial value of the variable the body of the loop gets executed.hope this helps

That's exactly what I was looking for. Thank you!
