--- Update ---

my problem is with my variables id , membership and gender in the sub class

Error comes up " cannot find symbol - constructor Member (java.lang.String,int,char)
Gratefull for any help

For future reference please wrap your code in the code tags to preserve formatting (see Announcements - What's Wrong With My Code? )

The error stats that the compiler cannot find that constructor. Take a close look at the Member class constructor, and how the line that throws the error is calling it: you've only got one constructor for the Member class and it accepts 5 parameters (whereas the JuvenileMember class tries to use a 3 parameter constructor)

It has to be able to find the Constructor to be able to call it. A 5 parameter constructor is not the same as a 3 parameter constructor.
