         System.out.println("a new Order arrived");
       // critical region  :
       synchronized (this) {
        EnterOven(/*MeatId, Degree, TimeToCook*/);
        ExitOven(/*MeatId, Degree*/);
    /*void ArriveOven(int Degree)
         System.out.println("Arrived in oven");
   synchronized void EnterOven(/*Cheff cheff/*int MeatId, int Degree, int TimeToCook*/)
        //System.out.println("Arrived in oven "+MeatId);
        while (Cheff.available1 == true) {
                try {
                              cheff.GetMeat();
                        //wait
                        //System.out.println("cooking meat # "+MeatId);
                        //Cheff.available--;
                        wait(/*TimeToCook*/300);
                        Cheff.available1 = false;
                } catch (Exception e) { }
        //Cheff.available = 0;
        Cheff.available1 = true;

Answer 1

  public Oven(Cheff cheff) {
         cheff = cheff;
    }should be:
  public Oven(Cheff cheff) {
         this.cheff = cheff; // Need "this." on left.
    }Otherwise, you are just assigning the local variable to itself.
