Explanation / Answer

In Java, Comparator is defined as an interface. The comparator can be used with various of the inbuilt function of sorting, etc to get an extra control over them. Eg. You want Arrays.sort to sort the number in reverse order. In such a case we will have to make use of the interface Comparator to tweak with the original logic of comparison behind the function SORT.

The interface provides us with two of the utility function:-

int comp(Object1, Object2)

This function is used to define the parameter or conditions based on which we can conclude that which Object is greater. Eg:- If the 2 objects were strings namely a & b, then

could have been used to determine which of the string object is greater than the other.
