Have created a superclass and made another class for testing but i get this error code, kindly help :p just newbie :(

Hmm I copied your code, placing all classes in the same package, and did not get that error. Some times that error arises when there is a missing import statement. This stackoverflow response also lists some of the other common reasons: https://stackoverflow.com/questions/25706216/what-does-a-cannot-find-symbol-compilation-error-mean#25706217
