Anyone familiar with java?

[Phobia]

I'm in need of some critical help with java. I have two tiny programs due by September 25th. I need my fellow OS crew to PLEASE give me a hand if you know java. I've read this Intro to Java book two times cover to cover and still lost.

So if you can give me a quick hand, please please please PM me.

Thanks guys!!

Google it. Not being sarcastic. A lot of the assignments are all from the maker of the booker so solutions are out there. Unless you have a professor who custom made all his assignments or it has to be something original. Just do a massive copy and paste of the instructions or any code already given to you.

Edit - But don't just copy the solutions! I took Java for a year too so I know the struggles. Nothing more frustrating than having no idea why something isn't working.

Not trying to get caught for plagiarism on my 4th year. Now with that said, I don't understand the instructions.

Be careful with this. Use it more as a guide than a solution manual. You want to make sure you learn it so that you can reproduce it later on a test or whatever if need be.

no test, submit the two applications and pass class. Its a throw away class basically.

Blah, sorry! I had "for assistance" in my head, didn't mean just to straight up copy.

Re: Anyone familiar with java?

Have you checked out "The New Boston" on YouTube ? I don't know how complex your assignments are but that guy has a knack for explaining programming stuff. It might help you grasp a concept you need for your class.

I wish I could help more but other than some super basic syntax, I don't know much java. I've got an ok grasp of C++ and now I've been reading up on C# which I hear is very similar to Java.

Good luck!

Re: Anyone familiar with java?

Can someone please look over this code why I'm getting this error. I can't seem to figure out how to fix it.

Thanks guys, I promise I won't have many more of these. After this project, I only have one more thank god. Then I never want to see java again.

Re: Anyone familiar with java?

You're trying to pass arguments into the function that are the wrong type. The function is looking for a double as the first argument, and an integer as the second. You're trying to pass an integer as the first, and a double as the second.
