  public static void main(String[] args) {
    
    //creating int values
    int val1 = 25;
    int val2 = -25;

    //printing hashcode of the int values
    System.out.println("hashCode of the val1 is: " + Integer.hashCode(val1)); 
    System.out.println("hashCode of the val2 is: " + Integer.hashCode(val2));
