class Dec26 {
public static void main(String[] args) {
short a1 = 6;
new Dec26().go(a1);
new Dec26().go(new Integer(7));
}
void go(Short x) { System.out.print("S "); }
void go(Long x) { System.out.print("L "); }
void go(int x) { System.out.print("i "); }
void go(Number n) { System.out.print("N "); }
}
Output:
i N
In the above example, why does the compiler choose the widening option (i.e. Integer --> Number) instead of unboxing the Integer and choosing the int option?
Thanks
