Cancer of the Semicolon

[l33tminion]

The following is only relevant to the programmers on my friends list, probably...

So, did you know that Java has syntactic sugar for iterating over a collection? So you can write this:

for (SomeType item: stuff) {
    // code here
}

Instead of:

for (Iterator<SomeType> iter = stuff.iterator(); iterator.hasNext();) {
    SomeType item = iter.next()
    // code here
}

I didn't until recently. When did that happen? Was that not around when I was first learning Java?

Despite that, I'm feeling more competent Java-wise lately. I feel that I finally understand the JNI (how to use it, anyways). I even got a C++ API for the multitouch hardware I'm using to play nicely with some Java code.

That got added in Java 5, so after the AP test, at least. Don't know how much Java you've done since then.

I seem to do bits here and there most jobs I'm on, but I hadn't seen that idiom in any of the code I worked with.
