Java Comparator This article will discuss comparable and comparators and find the difference between their definitions and their use cases in Java. Java Comparable A Comparable object in Java is used to compare itself with the other objects. We need to implement the java.lang.Comparable interface...
Java code: For Comparable: In this post, we will see how you can use comparable to sort list of objects in java. Comparable interface: Class whose objects to be sorted must implement this interface.In this,we have to implement compareTo(Object) method. For example: 1 2 3 4 5 6 7 ...
