   */
  public static void main(String[] args) {
    
    Student student = new Student("Sriram"2"Chess");
    Student student2 = new Student("Sudhakar"29"Painting");
    
    int hashCode = Objects.hashCode(student, student2)//Internally uses Arrays.hashCode
    System.out.println("Hash code : " + hashCode);
  }
