HashSet source code details

Preface

After writing the HashMap article, it took several days to continue this series of articles. Because there are too many things to learn and it takes a lot of time to write an article, it took several days to write it. But I hope I stick to it. One day we will see the blue sky through the clouds. If you want to learn HashSet, you should first understand HashMap, so if you don't understand HashMap, you can look forward to my article on HashMap. http://www.cnblogs.com/whgk/p/6091316.html
