If one is a beginner, as the original post would suggest, I would hesitate to recommend this advice. While IDE's do make things easier for more advanced programmers, there are many concepts which become hidden through an IDE and can only be learned by command line programming. Plus, this is suggestive that an IDE will solve the original issue, which we don't even know what it is.
if you are using notepad, I suggest you download an IDE such as Eclipse online. They have very easy tutorials on how to use them, and it makes programming much easier.
