Recently, I came across a code where --> was used. example: <pre class="prettyprint"><code>int a = 5; while(a-->0){ //do something 'a' times } </code></pre> Is <code>(a-->0)</code> equivalent to <code>(a-- > 0)</code> or simply, <code>((a=a-1) > 0)</code>? If not, I want to know what's that operator called, and are there other similar operators. If so, then where are they mentioned? Thanks

What is --> symbol in Java? [duplicate]

Recently, I came across a code where --> was used.

example:

int a = 5;
while(a-->0){
    //do something 'a' times
}

Is (a-->0) equivalent to (a-- > 0) or simply, ((a=a-1) > 0)?

If not, I want to know what's that operator called, and are there other similar operators. If so, then where are they mentioned?

Thanks

It's two operations. The postfix -- (a = a - 1 but effective on the next line) and a greater than. It's equivalent to something like

while (a > 0) {
    a = a - 1;
