Bridging mode (bridge) (object-structured mode)

Theoretical knowledge, you can refer to the reference document.

Look at the structure of bridge:

The structure of the window example that is spoken in the book:

Code implementation:

Brushpenabstraction.java:

Package com.rick.designpattern.bridge2;

/**

    protected implementorcolor implementorcolor;


    public void Setimplementorcolor (Implementorcolor implementorcolor) {

    } Public

    abstract void Operationdraw ();

}

    }
}
