Answer Posted / Sudhir Singh Chahar
"The Comparable and Comparator interfaces in Java are used for comparing objects. They help define a total ordering between instances of a class.n
1. Comparable Interface: A class implements the Comparable interface to compare its own instances. It defines the compareTo(Object o) method that compares the current object with another object passed as an argument. Each class can implement only one Comparable interface.
2. Comparator Interface: The Comparator interface is used for comparing two objects of any classes. It also defines a compare(T obj1, T obj2) method. Multiple Comparators can be created for a single class and they can be used to define different comparison rules."
