周四我们进行了ATM小程序考试，这个考试让我认识到了很多。首先老师给我们的两个星期我们没有利用好，这就相当于我们没有完成我们应该完成的作业。其次我感觉这次我获得了挺多，发现自己学的那些根本就是基本中的基本。在做程序的过程中我们还要用到Java语言的很多函数。恰巧这是看书看不到的，也不会注意看的。 在这次考试中我端正了自己的思想，不会再打没有准备的仗。我也在这次考试中学到了一些知识，比如声明vector，InIterator实现文件数据的导入导出，以及file 建立文件夹 ，FileInputStream，InputStreamReader，BufferedReader实现文件导入，FileOutputStream，OutputStreamWriter实现文件导出
