Error: java/lang/String & parsefloat not a method in class Float (j0235)

Question

Hi,
I don't know why i amgetting this error which says: 'unable to locate system class: java/lang/String.
I have compiled and executed the reader method separately on a command prompt and it is working, but when i do it in microsoft visual j++, i am getting this run time error.
I also have rt.jar in the classpath.
If i don't have this rt.jar in my classpath, it is giving me a compilation error: parsefloat is not a method in class Float (j0235).
somebody please help.
