Java expressions

Question

I am trying to understand this code in Java 7 environment,

int T = getIntVal();

while (T--> 0) {

 // do stuff here

}

T is not modified within the while loop. Can someone explain this code?

Answer 1

what confuses you is that there is no whitespace between the T-- and the >, so you might think there's a --> operator.
looking like this:

while (T-- > 0) {

}

It makes more sense, in every loop you decrease T by one
