體系結構—工廠方法模式

編寫一個工廠方法模式的程序

public interface clothingType {
	public void getType();    //打印選擇的服裝類型
}

public class t_shirt implements clothingType{
	@Override
	public void getType() {
		System.out.println("您選擇的是T恤");  	
	}
}

public class short_sleeve implements clothingType{
	@Override
	public void getType() {
		System.out.println("您選擇的是短袖");  	
	}
}

public interface IFactory {
	clothingType createType();
}

public class t_shirtFactory implements IFactory{
	@Override
	public clothingType createType() {
		return new t_shirt();
	}
}

public class short_sleeveFactory implements IFactory{
	@Override
	public clothingType createType() {
		return new short_sleeve();
	}
}

public class 服裝廠 {
	public static void main(String[] args) {
		//客戶端決定實例化哪一個工廠實現選擇服裝類型
		IFactory factory=new t_shirtFactory();    
		clothingType ct=factory.createType();
		ct.getType();
		
		factory=new short_sleeveFactory();
		ct=factory.createType();
		ct.getType();
	}
}
