Why does the expression: new Short(1); causes a compile-time error
while the expression: new Short("1"); does not?

[Saumya Tangeda]

Sorry, the first expression is resulting in run-time error NOT compile-time error.I understand why, but i don't get why the second one is OK.

[Keith Lynn]

No, the first one results in a compile-time error. There is no constructor
in Short.java that accepts an int.

By default, the number in
new Short(1)
is of type int. Thus, it produces compile error.

/* this works */
short num = 1;
Short s = new Short(num);
