Java.lang.Long.compareTo() Method


The java.lang.Long.compareTo() method compares two Long objects numerically.


Following is the declaration for java.lang.Long.compareTo() method

public int compareTo(Long anotherLong)


anotherLong − This is the Long to be compared.

Return Value

This method returns the value 0 if this Long is equal to the argument Long, value less than 0 if this Long is numerically less than the argument Long and a value greater than 0 if this Long is numerically greater than the argument Long (signed comparison).




The following example shows the usage of java.lang.Long.compareTo() method.

package com.tutorialspoint;

import java.lang.*;

public class LongDemo {

   public static void main(String[] args) {

      // compares two Long objects numerically
      Long obj1 = new Long(63255);
      Long obj2 = new Long(71678);
      int retval =  obj1.compareTo(obj2);
      if(retval > 0) {
         System.out.println("obj1 is greater than obj2");
      } else if(retval < 0) {
         System.out.println("obj1 is less than obj2");
      } else {
         System.out.println("obj1 is equal to obj2");

Let us compile and run the above program, this will produce the following result −

obj1 is less than obj2
