Why this code fail at runtime

public class Test{



public static void main(String[] args) {
Integer i = Integer.parseInt("0xF",16);
System.out.println(i);

}

}

The "0x" prefix is used by the compiler to inform the compiler to parse the following token as a hexidecimal string.

It is not needed, nor supported, by the Integer parseInt() method, as the radix is passed as a parameter.
