Example:

In the below example, the java.lang.Long.equals() method is used to compare given Long objects for equality.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    
    //creating Long objects
    Long val1 = new Long("5");
    Long val2 = new Long("5");
    Long val3 = new Long("-5");

    //checking Long objects for equality
    System.out.println("Is val1 == val2?: " + val1.equals(val2)); 
    System.out.println("Is val1 == val3?: " + val1.equals(val3));    
  }
}

The output of the above code will be:

Is val1 == val2?: true
Is val1 == val3?: false
