How to use java to implement Bubble sorting algorithm
This article mainly shows you "how to use java to achieve bubble sorting algorithm", the content is easy to understand, clear, hope to help you solve your doubts, the following let Xiaobian lead you to study and learn "how to use java to achieve bubble sorting algorithm" this article.
0x01, preface
In fact, I basically forgot the sorting algorithm I learned when I was a student, and I can't remember it at all. The reason is that I use ready-made methods and tools to move bricks every day, such as Collections.sort (), which is commonly used in java application development. Basically, I don't need our handwritten code, and gradually degenerate into a brick bearer.
0x02, knock on the blackboard, understand the idea of bubbling sort
The essence of bubble sorting is to compare the data size of adjacent elements from left to right, and exchange swap if a [j] > a [jig1]. Each sort will only put the unsorted elements at the back, that is, arr.length-1 sorting is needed, which is the basic idea of bubble sorting.
0x03, the implementation of Bubble sorting algorithm
0x04, why do you want to write a bubble sort by yourself?
In fact, there are many such articles on the network now, that is, the so-called catch a lot of similar articles, and their realization ideas, contents, and ways of realization are all exactly the same, so why do you still write them yourself? What's more, you are not as good as others tell you (to be honest). In fact, there are many similar articles on the Internet now, which is basically the routine of copy- > paste. I am also a learner myself. In the process of learning, of course, I should keep up with the excellent people with an excited heart. In this way, I want to make greater progress compared with myself in the past. Learning is for myself. Why do you care about other people's opinions?
The above is all the contents of the article "how to use java to achieve bubble sorting algorithm". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
