snakefactory.java~7~

前段时间帮同学写了个简单动画程序：“贪食蛇的原型”

package com.cxlife.snake;
//这是一个工厂类，用来造蛇的
public  class  SnakeFactory {
  private SnakeFactory(){}
  public  static  Snake getInstance(){
    try{
      //工厂类信息应该来自配置文件，不过在这我之间简单的指定为：com.cxlife.snake.DefaultSnakeFactory
      SnakeFactory sf = (SnakeFactory)Class.forName("com.cxlife.snake.DefaultSnakeFactory").newInstance();
      return sf.getInstance();
    }catch(Exception e){
      e.printStackTrace();
    }
    return null;
  }
}
