【Java之路】设计模式之简单工厂

interface Product { }

class ConcreteProduct implements Product { }

class ConcreteProduct1 implements Product { }

class ConcreteProduct2 implements Product { }

class SimpleFactory {
    public Product createProduct(int type)  {
        if(type == 1) return new ConcreteProduct1();
        else if(type == 2) return new ConcreteProduct2();
        return new ConcreteProduct();
    }
}

public class Main {
    public static void main(String[] args) {
        SimpleFactory simpleFactory = new SimpleFactory();
        Product product = simpleFactory.createProduct(1);
    }
