I was wondering why we can do:
Long l = 2L;
Float f = 2f;
Double d = 2d;
or even
Double d = new Double(2);
and not
Short s = 2s; //or whatever letter it could be
nor
Short s = new Short(2); //I know in this case 2 is an int but couldn't it be casted internally or something?
Why do we need to take the constructors either with a String or a short.
