Mealbuilder:

Public abstract class Mealbuilder {    private Meal Meal = new Meal ();    public abstract void Buildfood ();    public abstract void Builddrink ();    Public Meal getmeal () {        return Meal;    }}

Submealbuildera:

public class Submealbuildera extends Mealbuilder {    @Override public    void Buildfood () {        System.out.println ( "This is Submealbuildera food!");    }    @Override public    void Builddrink () {        System.out.println ("This is Submealbuildera drink!");}    }

Submealbuilderb:

public class Submealbuilderb extends mealbuilder{    @Override public    void Buildfood () {        System.out.println ("This is Submealbuilderb food!");    }    @Override public    void Builddrink () {        System.out.println ("This is Submealbuilderb drink!");}    }

Kfcwaiter:

public class Kfcwaiter {    private mealbuilder MB = null;    Public Kfcwaiter () {    } public    Kfcwaiter (mealbuilder MB) {        this.mb = MB;    }    public void Setmealbuilder (Mealbuilder MB) {        this.mb = MB;    }    Public Meal construct () {        mb.builddrink ();        Mb.buildfood ();        return Mb.getmeal ();    }}

Buildermethod (call):

public class buildermethod{public    static void Main (string[] args) {        Mealbuilder mb_1 = new Submealbuildera (); C16/>mealbuilder mb_2 = new Submealbuilderb ();        Kfcwaiter KFC = null;        KFC = new Kfcwaiter (mb_1);        Kfc.construct ();        KFC = new Kfcwaiter (mb_2);        Kfc.construct ();    }}
