The constructor for CommandLineView constructs a RentABike using new RentABike - there is no concrete implementation of RentABike.

More importantly, clv does not have a setRentABike method, so the Assembler is not able to do the injection.

Also, I do not understand why CommandLineView has a main method.

CommandLineView should look more like this:

public class CommandLineView {


  private RentABike rentaBike;


  public CommandLineView( ) {

    //nothing to do here

  }


  public void setRentABike(RentABike rentABike){

    this.rentABike = rentABike;

  }


  public void printAllBikes( ) {

    System.out.println(rentaBike.toString( ));

    Iterator iter = rentaBike.getBikes().iterator( );

    while(iter.hasNext( )) {

      Bike bike = (Bike)iter.next( );

      System.out.println(bike.toString( ));

    }

  }

}

I hope this helps
