建造者设计模式

       建造者设计模式属于对象的创建者模式。可以将一个产品的内部属性与对象的生成过程分开，从而使构建过程构建出具有不同内部属性的产品对象。下面贴代码

1：具体控制生成对象：TicketHelper

package builder;

public class TicketHelper {
	public void buildAdult(String info)
	{
		System.out.println("构建成人票逻辑："+info);
	}
	public void buildChildrenForSeat(String info)
	{
		System.out.println("构建有座儿童票逻辑："+info);
	}
	public void buildChildrenNoSeat(String info)
	{
		System.out.println("构建无座儿童票逻辑："+info);
	}
}

2：构造者类TicketBuilder

package builder;

public class TicketBuilder {
	public static Object builder(TicketHelper helper)
	{
		System.out.println("通过TicketHleper构建套票信息");
		return null;
	}
}

3：测试类：BuilderTest

package builder;

public class BuilderTest {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		TicketHelper helper=new TicketHelper();
		helper.buildAdult("成人票");
		helper.buildChildrenForSeat("有座儿童");
		helper.buildChildrenNoSeat("无座儿童");
		Object ticket=TicketBuilder.builder(helper);
	}

}
