Exception in thread "main" java.lang.NoClassDefFoundError:classname/java

can anybody tell me how to fix this problem....

Hi
Obviously it cannot find one of your classes!
Maybe the class is not in your classpath.
Maybe you've misspelled its name.
Maybe...

i hav set classpath.. even class mae is also correct..but even a simple HELLO program is not workin

This should probably be in the beginner's forum.

However, when you run your program, are you typing

"java classname.java"?

or are you typeing

"java classname"?

i hav typed " java class name " but still error occurs.. but i cleared it . i had to reinstall java it is okay now thank you guys for your comments

Exception in thread "main" java.lang.NoClassDefFoundError:classname/java

The "/java" at the end of the error message indicates that you have typed:

java classname.java

instead of:

java classname

Re-installing Java was not necessary... :roll:
