一、大致结构（其模式主要是具体的产品有对应的具体工厂）
1、抽象工厂类
2、抽象产品类
3、具体工厂类
4、具体产品类
二、代码
1、抽象工厂类
Factory.java
package com.factory;
public interface Factory {
Fruit createFruit();
}
2、抽象产品类
package com.factory;
public interface Fruit {
public void grow();
}
3、具体产品类Apple.java与Orangle.java
package com.factory;
public class Apple implements Fruit {
@Override
public void grow() {
System.out.println("我真在成长......");
}
}
package com.factory;
public class Orangle implements Fruit {
@Override
public void grow() {
System.out.println("grow......");
}
}
4、具体工厂类AppleFactory与OrangleFactory.java
package com.factory;
public class AppleFactory implements Factory {
@Override
public Fruit createFruit() {
return new Apple();
}
}
package com.factory;
public class OrangleFactory implements Factory {
@Override
public Fruit createFruit() {
return new Orangle();
}
}
5、测试类Test.java
package com.factory;
public class Test {
public static void main(String[] args) {
Fruit apple = new AppleFactory().createFruit();
Fruit orangle = new OrangleFactory().createFruit();
apple.grow();
orangle.grow();
}
}
