Hi, I'm new! I also need help.

[demuro1]

Hello,
I am new to the boards and to Java. I am currently taking a Java class at the JC and am presented with a problem I am unable to solve. I believe my code is correct. I may need to create a directory somewhere and if so I have not done that but I will provide the errors the code and the file paths for current problem. I am coding on a mac. That shouldn't make a difference but thought I'd throw it in there just in case.

Thanks so much for your help!

file paths: note that everything resides within the same folder

Hello,
I am new to the boards and to Java. I am currently taking a Java class at the JC and am presented with a problem I am unable to solve. I believe my code is correct.

I've been doing this for a bit longer than you, so if there's one thing that I want you to take away from this, and one thing that I've learned the hard way, is to get rid of that assumption: If the compiler tells you you're wrong, you can't hold the belief that you're right. Instead believe the compiler. In fact it is telling you where you're wrong -- the class that you're trying to use, Rectangle2DFloat, doesn't exist. Check the API and use the correct class, one that exists in the API. As for the other problem, BasicStroke, your statement is wrong -- you have declared no variable.

Another problem, if you're not using an IDE, then it is your responsibility to compile your code often perhaps after adding each new line of code, and not to add any new code until you've fixed your current compilation errors. If you don't do this, your program will be little more than a rat's nest of errors.
