Example

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
