Read the eclipse documentation.

and more important: how can I get error information and find error detail at compiler and interpreting(run)? in vc I can get error number (Cxxx ,LNKxxx)etc...and I can easily search it in msdn.

The java compiler's error messages are fairly self-explanatory. They don't have codes that you can look up, but for messages that you don't understand, you can search for the error message text on google and usually find something that will help.

Well, actually, you can if you get ahold of the source code for the library and attach it to the system jars. I wouldn't recommend it, though, because it's complicated and the source might become outdated next time you upgrade your JDK. I've done it just to see if it can be done, and it was a total PITA.

I like to use Ctrl-Click to navigate to a class and/or method.

If you have the code wrapped in a try/catch block, you can put your breakpoint inside the catch block.

Ah, something we do agree on. The Java compiler has always been nicer to me than any C compiler. The failures are quite descriptive indeed.
