面试题复习-常用设计模式-简单工厂模式

手写一个简单工厂模式

产品接口：

package com.ajax.pattern.simplefactory;

public interface Fruit {
    void desc();
}

产品1：

package com.ajax.pattern.simplefactory;

public class Apple implements Fruit {
    @Override
    public void desc() {
        System.out.println("苹果");
    }
}

产品2：

package com.ajax.pattern.simplefactory;

public class Orange implements Fruit {
    @Override
    public void desc() {
        System.out.println("橙子");
    }
}

工厂：

package com.ajax.pattern.simplefactory;

public class SimpleFactory {
    public static Fruit getFruit(String name) {
        switch (name) {
            case "apple":
                return new Apple();
            case "orange":
                return new Orange();
            default:
                return null;
        }
    }
}

运行：

package com.ajax.pattern.simplefactory;

public class Run {
    public static void main(String[] args) {
        SimpleFactory.getFruit("apple").desc();
    }
}
