零基础学java确实有难度,但困难倒也算不上

第一,准备好装备,软装硬装都要准备好。硬件上,你需要有个配置比较高的电脑,顶配倒不至于,但也千万不要弄个低配。有了电脑,基本上学习过程中也就没什么大笔支出了。有了电脑,你还需要在电脑上准备个好用的截图工具,和记笔记的软件。当然也可以用电脑自带的工具,像截图可以print键截图,再打开画图工具粘贴就行了,记笔记的话我推荐windows系统里的OneNote。还有,最好准备个大一点的笔记本,在纸上书写笔记所加深的印象可是要比在电脑上打字要来的牢固。像我就是在电脑上做比较全面的笔记,在笔记本上写重点内容。有书的话,也可以准备几个不同颜色的荧光笔,按重点内容,自己需要巩固的知识,自己看不懂需要思考或招人解答的内容用不同颜色标记出来。这里要记得,一个颜色代表一个含义,并且要一直持续下去,不要随意更换。

第二,规划好学习路线。这个很重要,在前期一定要规划好自己的学习路线。学习路线可以根据自己的实际情况进行规划,也可以直接在网上搜。

第三,寻找资源。这里的资源主要是指学习资源,像学习视频,书籍,学习网站,学习交流群等。视频的话我首推B站,直接在B站上搜索java就可以出现了。书的话,你在知乎上搜java书籍推荐之类的词就能搜到不少类似的问题,从这些问题的回答里找就行。学习网站我总结了不少,都在链接里了。这里我重点推荐里面的菜鸟教程、博客园和编程字典,这几个是我用着感觉最顺手也最常用的了。至于学习交流群,直接在QQ上搜就可以了,一搜就一大堆。

第三,勤加练习。学java没什么诀窍,就是多练,练多了也就熟了。但这里一定要记住:不要照着老师给的代码敲!不要照着老师给的代码敲!!不要照着老师给的代码敲!!!自己在练习敲代码时可以根据自己在笔记上记得重点敲代码,在前期可以把老师在课上敲的代码根据老师讲的重点内容进行改变。比如老师说这个代码里这个点必须这样敲,你可以把它改成别的,看看这样可不可以运行,如果不可以,是因为什么;如果可以,那就找人问问这是为什么,虽然我还没遇到改了内容之后可以运行的情况。等到后面自己对java已经有了一定的了解,能够自己敲代码了,那这个时候你就可以试着自己敲属于自己的代码来运行。总之,一定要多练习!
