See it in this way:

if (a < -b) {
    return false;
}

There is no <- operator in java.

Related, I've just found this question: What is the "-->" operator in C++?

@Jam: yet strangely enough no one upvoted the question. it is a valid very interesting question, imo. – Denis Tulskiy May 15 '13 at 06:22

There is no such operator in java. This means

if (a < -b) {

}

which is same as

if (a < -         b) {

}

The - sign need not be just by b.

For int types one could do

if (a <-- b) {

}

which will be same as

if (a < --b) {

}

This kind of stuff is possible.but there is no <- operator in java.it can be -b

int a=4; int b=-5;

if(a<-b){
    System.out.println("ela");
}
