最后
整理的这些资料希望对Java开发的朋友们有所参考以及少走弯路，本文的重点是你有没有收获与成长，其余的都不重要，希望读者们能谨记这一点。
其实面试这一块早在第一个说的25大面试专题就全都有的。以上提及的这些全部的面试+学习的各种笔记资料，我这差不多来回搞了三个多月，收集整理真的很不容易，其中还有很多自己的一些知识总结。正是因为很麻烦，所以对以上这些学习复习资料感兴趣，

论文报告：
总结：
经过近期对 java 面向对象程序设计、前端知识以及JAVA 框架的掌握和学习，以及这段时间这个毕业设计管理系统的开发，让我更加了解到 java 学习的重要性。在开发这个系统是哪个，我完成了多个实验以及毕业设计管理平台的功能测试，阶段的系统开发学习当中，我从认识到熟悉java，而后到能够自主运用相关技术，我发现了它确实有很多方便之处，比如java集抽象性和封装性以及继承性和多态性于一体，实现了对代码重用和代码扩充功能，提高了整体软件开发的速度和效率。比如管理员添加用户的时候报java.lang.NullPointException、解决的方法：查看控制台打印信息、发现添加的时候未填写相关信息、报java.lang.NullPointException、通过断电调试发现用户信息为空的数据项、在前端保存的时候必须填写用户完整相关信息或者数据库设置字段可以为空都可以解决、 我学习程序设计的主要目的就是提高自己实际问题的程序解决方案的关键技能和技术。
