HuTool is a comprehensive Java tool class library that reduces code duplication and simplifies common tasks like file handling, encryption, and network communication.

Version 3.x was a significant bridge in HuTool's history, though the library is currently on version 5.x+. 🛠️ Core Capabilities of HuTool Zero Dependencies: Minimal external jar requirements.

Modular Design: Use only the tools you need (Core, Setting, Log, etc.).

Human-Friendly: Methods are named intuitively (e.g., DateUtil.today()). 📦 Major Modules in Version 3.9

hutool-core: Basic support (Reflection, Proxy, Type conversion). hutool-crypto: Simple wrappers for AES, RSA, and MD5. hutool-http: A lightweight HTTP client. hutool-json: Fast JSON parsing and creation. hutool-poi: Simplified Excel/Word manipulation. 💻 Common Code Examples 1. Date and Time Handling

// Get current date as string String now = DateUtil.now(); // Parse strings easily DateTime date = DateUtil.parse("2023-10-01"); // Calculate age int age = DateUtil.age(date, DateUtil.date()); Use code with caution. Copied to clipboard 2. File Operations

// Copy file with one line FileUtil.copy("d:/test.txt", "d:/test2.txt", true); // Read content List lines = FileUtil.readLines("d:/test.txt", "UTF-8"); Use code with caution. Copied to clipboard 3. HTTP Requests

// Simple GET request String result = HttpUtil.get("https://google.com"); // POST with parameters HashMap paramMap = new HashMap<>(); paramMap.put("city", "New York"); String postResult = HttpUtil.post("https://weather.com", paramMap); Use code with caution.

A. StrUtil (String Tool)

Replaces Apache Commons Lang StringUtils.

import cn.hutool.core.util.StrUtil;
// 1. Null-safe checks
boolean isEmpty = StrUtil.isEmpty(str); 
boolean isBlank = StrUtil.isBlank(str); // Checks for null, empty, or whitespace only
// 2. Formatting (Uses {} placeholder, similar to SLF4J)
String template = "Hello, {}! Welcome to {}.";
String result = StrUtil.format(template, "User", "Hutool Guide");
// Output: "Hello, User! Welcome to Hutool Guide."
// 3. Substring
String sub = StrUtil.sub("Hutool Guide", 2, 5); // "tool"

The Core Philosophy

Hutool is designed around static utility methods. It follows the "Just call it" philosophy. You rarely need to instantiate objects; you just call XxxUtil.method().
