《Java设计模式》之构建者模式

生活中的例子：
             

import java.util.ArrayList;
抽象的创建者类，主要给具体的创建者类创建模板，具体的创建者继承该类后，重写方法，用自己的方式创建风格不同的复杂对象的属性。但总体复杂对象的结构已经固定。

abstract class Builder{
    public abstract void BuildDoor();
    public abstract void BuildWall();
    public abstract void BuildWindows();
    public abstract void BuildHouseCeiling();
    public abstract House GetHouse();
}

class House{
    private ArrayList <String>parts=new ArrayList<String>();
    public void add(String str){
        parts.add(str);
    }
    public void show()
    {
        for(String part:parts)
        {
            System.out.println(part+"\t");
        }
        System.out.println("\n");
    }
   
}

class Director{
    public void construct(Builder builder){
        builder.BuildDoor();
        builder.BuildWall();
        builder.BuildWindows();
        builder.BuildHouseCeiling();
    }
}

class ChineseBuilder extends Builder{
    private House chineseHouse=new House();
    public void BuildDoor() {
        chineseHouse.add("ChineseDoor");
    }
    public void BuildWall() {
        chineseHouse.add("ChineseWall");
    }
    public void BuildWindows() {
        chineseHouse.add("ChineseWindows");
    }
    public void BuildHouseCeiling() {
        chineseHouse.add("ChineseHouserCeiling");
    }
    public House GetHouse() {
        return chineseHouse;
    }
   
}

class EnglandBuilder extends Builder{
    private House englandHouse=new House();
    public void BuildDoor() {
        englandHouse.add("EnglandDoor");
    }
    public void BuildWall() {
        englandHouse.add("EnglandWall");
    }
    public void BuildWindows() {
        englandHouse.add("EnglandWindows");
    }
    public void BuildHouseCeiling() {
        englandHouse.add("EnglandHouserCeiling");
    }
    public House GetHouse() {
        return englandHouse;
    }
   
}
public class BuilderPattern {
    public static void main(String[] args) {
        Builder chineseBuilder=new ChineseBuilder();
        Builder englandBuilder=new EnglandBuilder();
        Director director=new Director();
        director.construct(chineseBuilder);
        House chineseHouse=chineseBuilder.GetHouse();
        chineseHouse.show();
        director.construct(englandBuilder);
        House englandHouse=englandBuilder.GetHouse();
        englandHouse.show();
    }

}
