Hi Guys,

K&B talks about the searching algorithm javac and java use to look for other classes and the first place they look is in the directories that contain the classes that come standard with J2SE. What are these directories and where are they located? In addition, the book mentions that JARs in ../jre/lib/ext are automatically searched for classes so I guess these classes may exist inside it. However, I can't find them. It bothers me a lot

Thanks a lot!

jre/lib/ext is for extensions, not for the core libraries. It's quite possible that there's nothing in there if you haven't installed additional libraries.

I'm not sure if that's true for all Java installations, but in mine the core libraries are in a file called "classes.jar".

Thanks, Ulf, I find it!
 
I'm sure glad that he's gone. Now I can read this tiny ad in peace!
