What is Comparable in Java

Question

Could you please give me a brief about Comparable in Java?

Answer 1

As the name itself suggests, Comparable is an interface which defines a way to compare an object with other objects of the same type. It helps to sort the objects that have self-tendency to sort themselves, i.e., the objects must know how to order themselves. Eg: Roll number, age, salary. This interface is found in java.lang package and it contains only one method, i.e., compareTo(). Comparable is not capable of sorting the objects on its own, but the interface defines a method int compareTo() which is responsible for sorting
