  public static void main(String[] args) {
	  
	  Long s1 = 76l;
	  Long s2 = 42l;
	  
	  int obj = Long.compare(s1, s2);
	  if(obj==0)
	  {
		  System.out.println("Both the long values are same.");
	  }
	  else if(obj>0)
	  {
		  System.out.println("The value '"+s1+"' is greater than "+s2);
	  }
	  else

The value '76' is greater than 42

Example 2

import java.util.Scanner;
public class JavaLongcompareExample2 {
  public static void main(String[] args) {
	  
	 Long age = 18l;

  Scanner scanner = new Scanner(System.in);
  System.out.print("Enter your valid age: ");
     Long userAge = scanner.nextLong();
    		 int com = Long.compare(age,userAge);
    		 if(com<=0) {
    			 System.out.println("You are eligible to vote.");
    		 }
    		 else {
    			 System.out.println("You are not eligible.");
    		 }
  }
}

Output:

Enter your valid age: 35
You are eligible to vote.

Example 3

import java.util.Scanner;
public class JavaLongcompareExample3 {
  public static void main(String[] args) {  
	 Long doy = 2018l;
  Scanner scanner = new Scanner(System.in);
  System.out.print("Enter your birth year : ");
     Long userAge = scanner.nextLong();
    		 int com = Long.compare(doy,userAge);
    		 if(com<=0) {
    			 System.out.println("PLEASE enter a valid birth year.");
    		 }
    		 else {
    			 long age=doy-userAge;
    			 System.out.println("You are "+age+" years old.");
     }
  }
}

Output:

Enter your birth year : 2020
