02.创建型————工厂方法模式

package Create.b.FactoryMethod;

//业务接口
public interface Salary {
	void calcSalary();
}

  

package Create.b.FactoryMethod;

//业务实现类
public class HeBeiSalary implements Salary {

	@Override
	public void calcSalary() {
		// TODO Auto-generated method stub
		System.out.println("开始计算河北子公司的薪资!");
	}

}

  

package Create.b.FactoryMethod;

//业务实现类
public class GuangDongSalary implements Salary {

	@Override
	public void calcSalary() {
		// TODO Auto-generated method stub
		System.out.println("开始计算广东子公司的薪资!");
	}

}

  

package Create.b.FactoryMethod;

//工厂接口
public interface Factory {
	Salary createSalary();
}

  

package Create.b.FactoryMethod;

//业务实现类工厂类
public class HeBeiFactory implements Factory {

	@Override
	public Salary createSalary() {
		// TODO Auto-generated method stub
		return new HeBeiSalary();
	}

}

  

package Create.b.FactoryMethod;


//业务实现类工厂类
public class GuangDongFactory implements Factory{

	@Override
	public Salary createSalary() {
		// TODO Auto-generated method stub
		return new GuangDongSalary();
	}

}

  

package Create.b.FactoryMethod;


//业务调用类
public class Client {
	public static void main(String[] args) {
		Factory fa = new HeBeiFactory();
		Salary sa = fa.createSalary();
		sa.calcSalary();
		
		fa = new GuangDongFactory();
		sa = fa.createSalary();
		sa.calcSalary();
	}
}

  

优点:每个实现类均有对象的工厂类

缺点:如果有新的实现类则需要添加新的工厂类,添加编写代码工作量
