零基础自学Java个人心得

学习计算机的主流方式主要是视频课程、书本、源码、博客等个人平台这几种。如果是纯小白,那么最推荐的就是视频课程,这种方式相比于博客来说更加系统,相比于直接去啃书本来说也更加易于理解(毕竟有老师的讲解,会相对通俗一点)。需要注意的是,这里的课程并不包括学校的课程,大多数本科院校学习的内容都较为基础,不够深入,想要只靠本科学习到的东西从事这个行业很困难,而且大家也都知道计算机更新迭代速度很快,暂不提学校课程与现在企业所用的技术是否存在脱轨现象,单就论我们大四毕业后才参加工作,大一大二所学的课程已经是四年前的了,肯定不够用。其实,学校老师的工作更像是一个领路人,“师傅领进门,修行在个人”,门已经进了,能走多远就看我们私下花多少功夫了。

 

当我们有一定基础后,就可以着手去读一些比较经典的教材了,比如Java程序员基本都知道的《Java核心基础》、《Java并发编程的艺术》、《深入理解Java虚拟机》、《Redis设计与实现》等,可以进一步的深入理解相关知识,并且有之前视频课程的铺垫,理解起来也更加容易。

 

对于博客,我更喜欢用它来查漏补缺,或者学习一些晦涩难懂的知识点,因为博客上的作者会把这些很难理解的知识点结合自己的理解,用各种通俗方式把它掰开、揉碎了讲解清楚,一篇看不懂就多看几篇,总有适合我们的。

 

至于源码,可以在我们学完基础后,深入学习并发编程、JVM等内容时进行参考,虽然大多数时候读源码是个很痛苦的事情,但是有些问题十行代码就能解释清楚好几页纸才能讲明白的事情。

 

以上就是我个人关于选择学习方式的一些心得,大家也可以结合自己的情况,选择适合自己的方式。但是不管选择什么方式学习,实践是必不可少的,学习编程最重要的就是敲代码!只有自己动手才会发现会自己存在哪些问题,有哪些没有掌握的内容,也只有多写多练,才能避免走到“背代码”的误区里。
