Now that we have some basics down, we want to start writing programs, as opposed to just snippets of code. For this, we need an IDE, an integrated development environment, which basically acts as spell check for code. There's many out there all with different pros and cons, with the top 2 contenders being Eclipse and NetBeans. Many people like Eclipse, it's a sort of catch-all and can be used for many languages, but I personally use NetBeans, the choice is yours. Google them both, try them out. See which one you like.
There's too much variance between IDEs and too many tweaks, so suffice to say, pick your own, and it'll probably not matter much in the end anyway. Next time, we'll begin writing a few simple programs using our IDE.
