Well, first: is the class name "Room1" or "room1"? Java cares -- it's case sensitive. Make sure you're typing the right one.

Have you compiled your class? In other words, is there now a file called Room1.class?

If all this is straightened out, then you may have a bad CLASSPATH setting. Try this:

java -cp . Room1

that's "java space dash cp space dot space Room1". That should work!

What are you giving at console as an Input...

room1 is my class name



and exception is

"Exception in thread "main" java.lang.noClassdeffoundError:Room1"



That mean you are typing

java Room1


you must try

java room1

Hope this helps.... If still any concern then revert with exact details.. what are you using....exactly...

See http://faq.javaranch.com/view?HowToSetTheClassPath

Pay special attention to the part that suggests not setting it at all! If you do choose to set it to something make sure "." (dot) is included.
