Main differences between Comparable and Comparator are:

1. Type: Comparable is an interface in Java where T is

the type of objects that this object may be compared to.

2. Comparator is also an interface where T is the type of

objects that may be compared by this comparator.

3. Sorting: In Comparable, we can only create one sort

sequence. In Comparator we can create multiple sort

sequences.

4. Method Used: Comparator interface in Java has

method public int compare (Object o1, Object o2) that

returns a negative integer, zero, or a positive integer when

the object o1 is less than, equal to, or greater than the

object o2. A Comparable interface has method public

int compareTo(Object o) that returns a negative integer,

zero, or a positive integer when this object is less than,

equal to, or greater than the object o.

5. Objects for Comparison: The Comparator compares two

objects given to it as input. Comparable interface

compares "this" reference with the object given as input.

6. Package location: Comparable interface in Java is defined

in java.lang package. Comparator interface in Java is

defined in java.util package
