Hello Folks,

I'm currently attempting to learn Java. I've purchased a book called "Learning Java" -O'Reilly, which comes with a nice little CD filled with examples in Eclipse. The files seem to have what I believe is labeled as a Cheat Sheet with a step by step tutorial type helper, prompting me to "Click When Complete" to go to the next step and place a "Check" next to the previous step I've completed.

So that's all fine and dandy, but here's my problem:

I ran into a couple issues with the example .java files not opening the Cheat Sheets properly in Eclipse because I accidentally changed *something* and couldn't figure out how to go back, so I decided to wipe it clean and uninstall/delete my Eclipse files and start over.

Now, whenever I try to open these .java examples that came with the CD, it prompts me with a window asking what I'd like to open them with. It only gives me an option of wordpad or notepad. When I try to manually browse and select the "Eclipse.exe", it doesn't recognize it and opens it as a notepad file anyway.

I've been trying to figure this out for a few hours, and have become quite agitated, lol.

Thanks in advance...

You don't mention explicitly from where you are trying to open the .java files, but it sounds like you are trying to do this from outside Eclipse. That won't work. Eclipse is project based not file based. You can't just open up a java file with Eclipse.

I'm not familiar with the book you referenced, but my guess is that the book has a section on how to setup the examples. I would re-read that portion and make sure you are following what it says.

Well, I've figured out how to import them now, but I've got a ton of errors. The book says I need to set the compiler to 5.0 compatibility, but 1.6 is the highest option I'm allowed to set. I'll see if I can fix a few more of the bugs.

Java version numbers got kind of messed up with version 1.5. Sun decided to start calling it 5.0 so 5.0 compatability is the same as 1.5

Oh, alright. That's weird. The rest of them I'm pretty sure I need to download certain tools/plug-ins, which I'll do as I go along.

Thanks for your help, very much appreciated.
