Following code works perfect and adds 1 and 2 values to the list, but why?
Why you don’t need to create Short objects explicitly? e.g: list.add(new Short(1));
List<Short> list = new ArrayList();
list.add((short)1);
list.add((short)2);
System.out.println(list);
This is called autoboxing. It is a feature that automatically converts primitives to their corresponding object type. It is present since Java 1.5.
The opposite of autoboxing is called autounboxing but beware of NullPointerException
