Actually i didn't get this point...

As i have made one program & save in my path "D:\Java_Programs\"....

After that i compiled my program as below.

C:\ javac D:\Java_Programs\Example.java

after that there was no error then execute my program

C:\ java D:\Java_Programs\Example

so i got errors. its mention below

"Exception in thread "main" java.lang.Noclassdeffounderror".

Can you please help to rectify above error.

If you have set the CLASSPATH to \Java_Programs\
then the below will work
C:\ java Example


or try this..
C:\ java -cp D:\java_programs Example

I guess the best way would be .
Go the command prompt
C:\ set classpath=<path of lib folder in your jdk ex. C:\Proram FIles\j2sdk 1.4.2\lib>;.;
The ;.; makes sure your this apth gets concanated to your existing class path.
ALso set the path in the same way but make it to pint to bin folder of jdk.
Hope it helps :-)
