代码高亮插件双击即可选中，不过部分同学反应，通过代码高亮插件复制的代码无法在IDEA里正常显示，这里提供TEXTAREA的方式，方便复制，谢谢
1. 自行完成练习
根据练习目标尽量自己实现代码效果，期间会碰到疑问，难题，和自己不懂的地方，这些都是必要的过程
2. 带着疑问查看答案
完成过程中，碰到无法解决的问题，带着疑问，查看答案，分析答案的解决思路
3. 查看答案讲解视频
依然有不明白的地方，点开视频讲解，带着疑问，听视频讲解有问题的部分
4. 再做一遍
理解后，再从头做一遍，把有疑问的地方都捋清楚
5. 总结
最后再总结一遍，总结思路，总结解决办法，以后遇到类似的问题，怎么处理
HOW2J公众号，关注后实时获知布最新的教程和优惠活动，谢谢。
