JavaGuide 的Star数量虽然比较多,但是它的价值和含金量一定是不能和 Dubbo、Nacos这些优秀的国产开源项目比的。希望国内可以出更多优秀的开源项目!

另外,希望大家对面试不要抱有侥幸的心理,打铁还需自身硬! 我希望这个文档是为你学习 Java 指明方向,而不是用来应付面试用的。加油!奥利给!

JavaGuide介绍

开源 JavaGuide 初始想法源于自己的个人那一段比较迷茫的学习经历。主要目的是为了通过这个开源平台来帮助一些在学习 Java 或者面试过程中遇到问题的小伙伴。

  • 对于 Java 初学者来说: 本文档倾向于给你提供一个比较详细的学习路径,让你对于Java整体的知识体系有一个初步认识。另外,本文的一些文章 也是你学习和复习 Java 知识不错的实践;
  • 对于非 Java 初学者来说: 本文档更适合回顾知识,准备面试,搞清面试应该把重心放在那些问题上。要搞清楚这个道理:提前知道那些面试常见,不是为了背下来应付面试,而是为了让你可以更有针对的学习重点。
