Hello, everyone, I am for the majority of programmers brothers worry broken heart xiaobian, every day to recommend a small tool/source, full of your favorites, every day to share a small skill, let you easily save development efficiency, do not work overtime do not stay up late do not lose hair, is my goal!

Hutool is a small and complete Java tool class library, Hutool through the static method encapsulation, reduce the cost of learning related API, improve work efficiency, so that Java has the elegant functional language, let the Java language can also be “sweet”.

The tools and methods in Hutool come from the elaboration of each user. It covers all aspects of the underlying code of Java development. It is not only a sharp tool to solve small problems in large project development, but also an efficiency responsibility in small projects.

Hutool is a friendly alternative to the util package in a project. It saves developers the time to encapsulate common classes and common tool methods in a project, enables development to focus on the business, and avoids bugs caused by incomplete encapsulation to the maximum.

The sample code

The goal of Hutool is to replace a piece of complex code with a tool method that minimizes copy-and-paste code problems and revolutionizes the way we write code.

Take the MD5 calculation as an example:

  • [Previous] Open the search engine -> search “Java MD5 encryption” -> open a blog -> copy and paste -> Change to use
  • Hutool -> secureUtil.md5 ()

Hutool exists to reduce code search costs and avoid bugs caused by uneven code on the web.

Contains the components

Util utility class a Java basic utility class that encapsulates JDK methods such as files, streams, encryption and decryption, transcoding, re, threads, and XML. Util utility classes provide the following components:

Each module can be imported individually as required, or all modules can be imported by hutool-all.

At the end

This issue is to share here, I am xiaobian South wind blowing, focus on sharing interesting, novel, practical open source projects and developer tools, learning resources! I hope to learn and communicate with you together. Welcome to follow my official account ** [Github navigation station] **.
