**Hutool** is a small but comprehensive library of Java tools, encapsulation by static methods, reduce the cost of learning related APIs, increase productivity, and make Java as elegant as a functional programming language,let the Java be "sweet" too.
**Hutool** tools and methods from each user's crafted, it covers all aspects of the underlying code of Java development, it is a powerful tool for large project development to solve small problems, but also the efficiency of small projects;
**Hutool** is a project "util" package friendly alternative, it saves developers on the project of common classes and common tool methods of encapsulation time, so that development focus on business, at the same time can minimize the encapsulation is not perfect to avoid the bugs.
### Origin of the 'Hutool' name
**Hutool = Hu + tool**，Is the original company project after the stripping of the underlying code of the open source library , "Hu" is the short name of the company , 'tool' that tool .
Hutool,' Hútú '(Chinese Pinyin)，On the one hand, it is simple and easy to understand, on the other hand, it means "hard to be confused".(note: confused means 'Hútú (糊涂)' in china )
The goal of **Hutool** is to use a simple function instead of a complex piece of code, thus avoiding the problem of "copy and paste" code as much as possible and revolutionizing the way we write code.
To calculate MD5 for example:
- 【Before】Open a search engine -> search "Java MD5 encryption" -> open a blog -> copy and paste -> change it to work.
- 【Now】import Hutool -> SecureUtil.md5()
Hutool exists to reduce code search costs and avoid bugs caused by imperfect code on the web.
A Java-based tool class for files, streams, encryption and decryption, transcoding, regular, thread, XML and other JDK methods for encapsulation，composing various Util tool classes, as well as providing the following modules：
| v5-master | The master branch, the branch used by the release version, is the same as the jar committed to the central repository and does not receive any pr or modifications. |
| v5-dev | Development branch, which defaults to the next SNAPSHOT version, accepts modifications or pr |
### Provide feedback or suggestions on bugs
When submitting feedback, please indicate which JDK version, Hutool version, and related dependency library version you are using.
Hutool welcomes anyone to contribute code to Hutool, but the author suffers from OCD and needs to submit a pr (pull request) that meets some specifications in order to care for the patient.：
1. Improve the comments, especially each new method should follow the Java documentation specification to indicate the method description, parameter description, return value description and other information, if necessary, please add unit tests, if you want, you can also add your name.
4. Please pull request to the `v5-dev` branch. Hutool uses a new branch after 5.x: `v5-master` is the master branch, which indicates the version of the central library that has been released, and this branch does not allow pr or modifications.
