public class Array
{
    public static void main(String[] args)
    {
        for (int i = 0; i < args.length; ++i) {
            System.out.println(args);
        }

        // Java 5.0
        for (String element : args) {
            System.out.println(element);
        }
    }
}

The first will work with any Java version. The second works only in Java 5. The arrays in Java have a length, similar to C++'s STL std::vector (I actually spend all of my time writing C++, but am familiar with Java).

I noticed that the first guy who wrote the loop used "i++". I'm in the habit of writing "++i". Because Java doesn't have operator overloading, it probably doesn't matter, but in C++ "++i" is more efficient than "i++".
