Yuck!
I am kinda getting fed up with the way the language implementers of Java continually add all these conveniences, but leave them 1/2 baked.
Example:
01public class UnboxTest {
02 @Test
03 public void testUnbox() {
04 final Integer a = Integer.valueOf(10);
05 final Integer b = null;
06 unboxIt(a);
07 unboxIt(b);
08 }
09 void unboxIt(final int value) {
10 System.out.println("Value: " + value);
11 }
12}
Guess what happens when you run this code?
A big, fat NullPointerException on line 7.
Oh yeah… Autoboxing
is supposed to be soo helpful, but they can’t default a frigging null to the default value of an int. (I.e. 0)
See my previous post for similar problems in the Java 5 foreach syntax.
