最后 按照上面的过程,4个月的时间刚刚好。当然Java的体系是很庞大的,还有很多更高级的技能需要掌握,但不要着急,这些完全可以放到以后工作中边用别学。 学习编程就是一个由混沌到有序的过程,所以你在学习过程中,如果一时碰到理解不了的知识点,大可不必沮丧,更不要气馁,这都是正常的不能再正常的事情了,不过是“人同此心,心同此理”的暂时而已。 “**道路是曲折的,前途是光明的**!” ![](http://www.www.zyiz.net/i/li/?n=2&i=images/20210707/1625614083890395.jpg) ![](http://www.www.zyiz.net/i/li/?n=2&i=images/20210707/1625614084375556.jpg) **[更多Java核心笔记、真实面经、学习笔记等知识干货可以点击这里免费领取](https://docs.qq.com/doc/DSmxTbFJ1cmN1R2dB)**
