If you are going to graduate in computer programming the most important thing you'll have to learn is precision. By this I mean it's not good enough to write "nxt" when you mean "next" or "wanna" when you mean "want to". Also capitalisation and punctuation are of paramount importance.
In a brief four or five line paragraph like the one that you have written, it is easy to spot simple, fundamental mistakes. In pages and pages of Java - or any other programming language - it is very difficult to spot syntax errors. You have to learn not to make the mistakes in the first place!
There is no easy route to being a programmer; you just have to work hard at it.
