Hi, Swetha Welcome to Javaranch.

It is because you are trying to run a Java program with a JVM version that was older than what I compiled it with. I think it is because of the classpath. Do you have set it correctly?


Life is easy because we write the source code.....

Nothing at all to do with the classpath.

1. Are you compiling and running the code on the same machine?
2. What are the outputs of the following commands?


luck, db
