If I don't have an IDE when I program (and I do significant work from Notepad2), I like to compile and see what went wrong. I usually don't get those method names correctly. I misspell, or mis capitalize, or forget to put a closing bracket or something.
A compile gives me all those errors in a format that I can see and fix immediately. Runtime errors means that I have to fix those erorrs one by one. This isn't fun.
