Comparable provides compareTo method to sort elements in Java whereas Comparator provides compare method to sort elements in Java. Comparable interface is present in java. Comparable provides single sorting sequence while Comparator provides multiple sorting sequences.

Comparator provides compare method to sort elements in Java. Comparator interface is present in java. The logic of sorting must be in the same class whose object you are going to sort.

The logic of sorting should be in separate class to write different sorting based on different attributes of objects. The class whose objects you want to sort must implement comparable interface. Class, whose objects you want to sort, do not need to implement a comparator interface. It provides single sorting sequences. It provides multiple sorting sequences. This method can sort the data according to the natural sorting order. This method sorts the data according to the customized sorting order.

It affects the original class. It is implemented to sort instances of third-party classes. Let's see an example of the Java Comparator interface where we are sorting the elements of a list using different comparators. This class provides comparison logic based on the name. In such case, we are using the compareTo method of String class, which internally provides the comparison logic.
