/** * 抽象产品 * @author hejinlai * */public interface Product { public void fun();} 第一个具体产品 ConcreteProduct.java :
/** * 具体产品 * @author hejinlai * */public class ConcreteProduct implements Product { @Override public void fun() { System.out.println("ConcreteProduct -> fun()"); }} 第二个具体产品 ConcreteProduct2.java :
public class ConcreteProduct2 implements Product { @Override public void fun() { System.out.println("ConcreteProduct2 -> fun()"); }} 抽象工厂 Factory.java :
/** * 抽象工厂 * @author hejinlai * */public interface Factory { public Product getProduct();} 第一个具体工厂 ConcreteFactory.java :
public class ConcreteFactory implements Factory { @Override public Product getProduct() { return new ConcreteProduct(); }} 第二个具体工厂 ConcreteFactory2.java :
public class ConcreteFactory2 implements Factory { @Override public Product getProduct() { return new ConcreteProduct2(); }} 测试 Test.java :
/** * 测试类 * @author hejinlai * */public class Test { public static void main(String[] args) { /*Product product = SimpleFactory.getProduct(); product.fun();*/ Factory factory; Product product; factory = new ConcreteFactory(); product = factory.getProduct(); product.fun(); factory = new ConcreteFactory2(); product = factory.getProduct(); product.fun(); }} 测试结果：
