do a save as to another location. If this does not work copy your code and create a new java file. Paste it and rename your class to the new file name.

How are you running your java program? From the command line?

If it compiles, but can't find the class, the typical problem is that your class compiles in one direction, and you want to run your program from a different directory.

By default, the java program assumes you have the class in the same directory. Otherwise, you need to specify it's location using the -cp (directory of class here) switch. Also, be sure not to put .java at the end of the class name.

I think u do not set class path properly
when u compile a file it must be in the same directory but u can run it anywhere

set path and classpath in invironment vriable as
go start-> control panel->system->advanced->environment variables->

path
.;%path%;c:/jdk1.4/bin;

classpath
.;%classpath%;c:/jdk1.4/lib;
