Difference between Comparable and Comparator
Comparable and Comparator both are interfaces and can be used to sort collection elements.
|1) Comparable provides a single sorting sequence. In other words, we can sort the collection on the basis of a single element such as id, name, and price.||The Comparator provides multiple sorting sequences. In other words, we can sort the collection on the basis of multiple elements such as id, name, and price etc.|
|2) Comparable affects the original class, i.e., the actual class is modified.||Comparator doesn't affect the original class, i.e., the actual class is not modified.|
|3) Comparable provides compareTo() method to sort elements.||Comparator provides compare() method to sort elements.|
|4) Comparable is present in java.lang package.||A Comparator is present in the java.util package.|
|5) We can sort the list elements of Comparable type by Collections.sort(List) method.||We can sort the list elements of Comparator type by Collections.sort(List, Comparator) method.|
