    abstract public class MediaContainer <T>{
      abstract T DisplayName(T Dispname);}

    which i want to override in here

    public class People <T> extends MediaContainer <T> {
        @Override public T DisplayName(T Person){
            return System.out.println(Person);

    You need to tell us what error you're seeing, but one glaring error is that you can't declare a method to return T and have it return void. In fact you can't ever return void which is what out.println(...) returns.
