Mkay so I want to start programming Java, and I have a new macbook pro with the Mac OS X built in, and so where in the world do I start?! I've opened up the terminal, but now what? I want to just do the "Hello, World!", and I have no clue where to begin. I have the code and I just don't know where to type it. If I just start typing in the terminal, it gives me an error since I can't go farther than the next line. I've read things about, oh, just type in 'pico', or download NetBeans. Which leads me to another question. Is NetBeans necessary? I thought everything you needed was already built in. Also, if I do indeed need NetBeans, which one should I download? There's like 5 or 6 options! Help please!
