Look at this SSCCE:

Integer[] array = new Integer[10];
public void doSomething() {
array.intValue(); /* fails, calling on the array instead of the
element */
array[0].intValue(); /* succeeds */
for (int i = 0; i < array.length; ++i) {
System.out.println(array[i].intValue()); /* succeeds */
}
}
}
These calls marked "succeeds", while they successfully compile, only succeed at runtime if each invoked array element is non-null.
This is not relevant to the compilation issue but might be important to those who forget that newsgroup examples sometimes intentionally omit details for pedagogical purposes that would be problematic in actual production. In production code one would anticipate a NullPointerException.
