The classfile is not there so u just keep teh file in
teh calsspath and run it

please use the following command

java -cp . DeitelDrawing

note space before and after the dot

from the command line

You got an error message java.lang.NoClassDefFoundError, this should happen
when you are trying to compile java  program with wrong name. for ex. (1)If
your program's name is DeitelDrawing you may have entered javac
deiteldrawing or javac Deiteldrawing, as you already know JAVA is case
sensitive. So please check you have entered class  name as you specify while
creating it. (2)Or you may have in other folder than your class is in? (3)
Or check your classpath.



I hope this is helps you?

Include rt.jar in your CLASSPATH.

try setting classpath properly .. just add u r java class  to the classpath

or if you don't want to set every class  you ever write to the classpath,
you can just include . in your classpath. It tells your OS to include
everything in the current directory in the classpath.
