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!");
	}

}
