03.建立型————抽象工廠模式

package Create.c.AbstractFactory;

//業務接口
public interface Salary {
	void calcSalary();
}

　　

package Create.c.AbstractFactory;

//業務接口
public interface Tax {
	void calcTax();
}

　　

package Create.c.AbstractFactory;

//業務實現類
public class HeBeiTax implements Tax {

	@Override
	public void calcTax() {
		// TODO Auto-generated method stub
		System.out.println("開始計算河北子公司的稅收！");
	}

}

　　

package Create.c.AbstractFactory;

//業務實現類
public class HeBeiSalary implements Salary {

	@Override
	public void calcSalary() {
		// TODO Auto-generated method stub
		System.out.println("開始計算河北子公司的薪資！");
	}

}

　　

package Create.c.AbstractFactory;

//業務實現類
public class GuangDongTax implements Tax {

	@Override
	public void calcTax() {
		// TODO Auto-generated method stub
		System.out.println("開始計算廣東子公司的稅收!");
	}

}

　　

package Create.c.AbstractFactory;


//業務實現類
public class GuangDongSalary implements Salary {

	@Override
	public void calcSalary() {
		// TODO Auto-generated method stub
		System.out.println("開始計算廣東子公司的薪資!");
	}

}

　　

package Create.c.AbstractFactory;

//工廠接口
public interface Factory {
  Salary createSalary();
  Tax createTax();
}

　　

package Create.c.AbstractFactory;

//業務實現類工廠類
public class HeBeiFactory implements Factory {

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

	@Override
	public Tax createTax() {
		// TODO Auto-generated method stub
		return new HeBeiTax();
	}

}

　　

package Create.c.AbstractFactory;


//業務實現類工廠類
public class GuangDongFactory implements Factory {

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

	@Override
	public Tax createTax() {
		// TODO Auto-generated method stub
		return new GuangDongTax();
	}

}

　　

package Create.c.AbstractFactory;


//業務調用類
public class Client {
public static void main(String[] args) {
	Factory fa = new GuangDongFactory();
	Salary sa = fa.createSalary();
	Tax tax =  fa.createTax();
	sa.calcSalary();
	tax.calcTax();
	
	fa = new HeBeiFactory();
	sa = fa.createSalary();
	tax =fa.createTax();
	sa.calcSalary();
	tax.calcTax();
	
	
}
}

　　

優勢：全部實現類設計到一個工廠類裏面，客戶端調用變得很是簡單，而且若是須要更換一個系列的產品，只須要更換一個工廠類便可

缺點：若是涉及需求變動或添加，則須要修改抽象工廠類，並同時修改實現這個抽象工廠類的具體實現類，添加額外編碼的工做量(跟工廠方法模式相同)
