What this article shares with you is about the difference among string, stringbuffer and stringbuilder. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Without saying much, follow the editor to have a look.

1. String is preferred in business scenarios where strings do not often change (the code is clearer and more concise). Such as constant declarations, a small number of string operations (concatenation, deletion, etc.).

2. In the case of single thread, if there are a large number of string operations, StringBuilder should be used to manipulate strings. Instead of using String "+", you can use it to avoid producing a large number of useless intermediate objects, space-consuming and inefficient execution (it takes a lot of time to create new objects and recycle objects). Such as JSON packaging and so on.

3. In the case of multithreading, if there are a large number of string operations, StringBuffer should be used. Such as HTTP parameter parsing and encapsulation.

These are the differences among string, stringbuffer and stringbuilder. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
