WebJava Comparator interface is used to order the objects of a user-defined class. This interface is found in java.util package and contains 2 methods compare (Object obj1,Object obj2) and equals (Object element). It provides multiple sorting sequences, i.e., you can sort the elements on the basis of any data member, for example, rollno, name, age ...

WebThe Comparator interface of Java is present in java.util package. This interface contains 2 methods compare (Object obj1, Object obj2) and equals (Object element). By default, we can not compare the objects of a user-defined class. To make an object of a user-defined class comparable, the class must implement the Comparable interface. WebCompares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. …
