Dirty Code

[Mike Tango]

Dear ALL,

Sorry to post here,

I write java code since 3 years (at work), (Most of the time copy paste from internet/forum...)
Sometimes it works but I don't know why / sometime it doesn't work and don't know why either .....

I really want to understand the core of java...
After 3 years I figure out that I write dirty code  


How can you advice me to solve this problem...

Regards,
Mike

I am a believer of never ever writing, even a single line of code, that you do not understand. Without an understanding of the code, you can't confirm, if what you did works for all cases, and/or if you introduced another bug.

Don't have a strong recommendation on what to do, except, you have three years of code, that some you don't understand. Perhaps it would be a good idea to go back and understand it?

Isn't it obvious ? Don't copy-paste. Write your own code, design your own structure. You can ask help here at coderanch any time, we will help you out.

Mike,
You'll have to go back to the beginning. Get a book on Java and start going through it. Write lots of code. Ask questions here when you don't understand something.

There's no magic; it takes hard work. And it isn't going to get easier if you go on cobbling stuff together by copy/paste. I was just talking to someone the other day about "experienced Java developers" who can't write simple code. We don't hire them. You don't want to be that guy.

. . . and welcome to the Ranch

Another thing: show some of your code to experienced people, for example here.

Thank you for your support.
