Java开学考试感想及代码
作者:互联网
本次开学考试是对Java基础的考察,做的是一个公寓宿舍管理系统,比上届的论文查重系统简单的多,但结果却差强人意,
在家中的学习和练习还不够,导致编程的时候题目的功能并不能实现,最后导致编程的结果不尽人意。
最后在学习Java的过程中我得出这样的结论:
1.学习中,要养成良好的习惯(写括号时要成对,字母大小写要区分,单词拼写要准确)。
2.在学习的过程中,最好不是仅仅停留在java表层,不是抄书上的例子运行出结果就可以。要注意,即便对一个简单的例子也要有耐心去琢磨、调试、改动。
3.在学习的过程中一定要动手做、试着写代码,而不是抱一本书看看就行。很多东西和体会必须自己动手才能真正属于自己。
4. 在 Java 的学习过程中,可能会遇到形形色色的问题不容易解决,应多去专业论坛了解相关的知识,书本上的知识有限。要会从网上搜索有用的信息 加以整理,促进学习的深入和知识水平的提高。
看了好多网上课程,说学到一定程度要尝试着自己做东西,但觉得自己仅仅经过一学期的学习,还远远不够,希望自己在以后学习中继续努力,能够真真正正拥有一门编程语言,对自己今后的发展起到作用。在学习java语言的同时,也让我学会了如何来发现问题,如何解决问题,怎样有效的学习等等,相信会对我一生都有帮助。
