Why aint this working???

Question

have pasted object thru a constructor like this:
        Write screen   = new Write(ring);
//and rezive it here in the constructor
     public Write(Object ring)
          buffer = ring;
// and use it like this:
          System.out.println(buffer.remove()); // This line gets an errorSo why is this error comming?
cannot resolve symbol method remove()

Answer 1

public class RingBuffer
    public static void main(String[] args)
         Ringen ring = new Ringen();
         Write screen   = new Write(ring);  // Henter tekst fra ringbuffer og skriver den ut p? skjermen.
         Generate genr  = new Generate();   // Lager tekst "automatisk" og legger den inn i ringbufferen.
         Input_txt intxt= new Input_txt(ring);  // Lar brukeren taste inn noen ord som lagres i ringbufferen.
         screen.start(); //
         genr.start();   //  Starter tr?dene.
         intxt.start();  //
