It happens because your class is not in your classpath.
You need to include the directory that contains your class in you classpath.

eg. if your class file is in c:\javastuff\test.class

then use:

java -classpath c:\javastuff test

or if you are in the same directory as the classpath you can use:

java -classpath . test

Or you can set the classpath environment variable:

eg.

set CLASSPATH=c:\javastuff;%CLASSPATH%

java test
