You can found comparator interface in java.util.package and it contains 2 methods. Thus 2 of those methods are : .compare(obj1, obj2) and equals(Object element)

compare() method

public int compare(object1, object2)

compareTo(Object obj) method

Hence, Here is a list of what the element we can sort :
