第一次Java测试及感触(2018.9.20)
在本周周四进行了java测试,有一点感触,测试的题目是用Java实现一个ATM机的管理系统。之前老师提前给我们样卷,结果考试的时候换了题型,瞬间脑子空白,一时不知道怎么下手,因为暑假虽然涉猎了java,但是没有深入系统地进行学习,导致了对很多知识一知半解,遇到很多问题束手无策。经过三个钟头的挣扎,只完成了一小部分的代码,只有简单的set()get()函数,以及简单的输出界面,能够输出ATM的初始界面,能够输入银行卡号,数据库也只是建立了一个大概。
后来在课后又对代码进行了断断续续的修改,对从网上找来的数据库代码段进行了较大修改,然后简单的补了其他部分的程序。
通过这次测试,我明白了初学者离熟练编写代码还有一段很长的距离,基本数据类型、数组、程序控制语句等都得在练习中熟悉,在之后的几天内,得知有人已经编出了图形窗口界面(为了简便起见我并没有往这方面想),便突然有了斗志,成长路上有这样全心向前的战友相信对我的正面帮助会很大。
以后每天要抽出时间进行代码习题的练习,熟能生巧,同时也要多读相关书籍,争取能在期末考试得到自己想要的结果。
