Return type from a Comparator

Question

What does the return value inside the Comparator actually mean?

For example :

class TreeSetDemo
{
    public static void main(String         


        

Answer 1

You are confusing return-type and return-value. The return-type is int. The return value is described in the documentation:

Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
