        T - the type of the object to be cloned
        Parameters:
        original - the object to copied, may be null

      • equals

        public static boolean equals​(java.lang.Object o1,
                             java.lang.Object o2)
        Checks and answers if the two objects are both null or equal. 
         Objects.equals(null, null) == true
 Objects.equals("Hi", "Hi") == true
 Objects.equals("Hi", null) == false
 Objects.equals(null, "Hi") == false
 Objects.equals("Hi", "Ho") == false
        Parameters:
        o1 - the first object to compare
        o2 - the second object to compare
        Returns:
        boolean true if and only if both objects are null or equal according to equals invoked on the first object
