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.
