Hutool 39
Calculates difference in days, hours, minutes, or seconds.
Hutool is modular. You can import hutool-core or hutool-http individually if you don't want the whole library.
Java's legacy Date class is notoriously difficult to work with. Hutool streamlines this.
// Safely check if a string is empty boolean isEmpty = StrUtil.isEmpty(str); // String slicing and padding String sub = StrUtil.sub("Hutool", 1, 4); // "uto" String padded = StrUtil.padPre("1", 3, '0'); // "001" Use code with caution. C. File and IO Operations ( FileUtil )

Handling files without throwing unnecessary exceptions is a breeze.
If you are starting a new project today, it is highly recommended to use the to ensure you have the latest security updates and performance optimizations. Conclusion
Hutool 5.8.39 is the latest stable release (as of June 2025) of the popular open-source Java tool library. It serves as a comprehensive "util" package alternative designed to reduce code complexity and increase development efficiency.

// Date arithmetic Date tomorrow = DateUtil.offsetDay(date, 1); boolean isWeekend = DateUtil.isWeekend(date);
The most notable expansion in recent releases is inside the AI module. Hutool 5.8.39 incorporates advanced parameters for , including custom timeout configurations and integrated fallback callbacks. This addition makes streaming real-time tokens into user interfaces straightforward.
39. Hutool是一个小而全的Java工具类库，通过静态方法封装，降低相关API的学习成本，提高工作效率，使Java拥有函数式语言般的优雅，让Java语言也可以“甜甜的”。 Maven Repository hutool/README-EN.md at v5-master - GitHub
For those new to Hutool, the library fundamentally changes how you write Java code. Where previously you might search online for "Java MD5 encryption" and copy-paste unreliable solutions, Hutool provides simple one-line static method calls like SecureUtil.md5() . Java's legacy Date class is notoriously difficult to
The XXXToMapCopier class (used in object-to-map conversions) has been optimized for better performance. This improvement is especially beneficial for applications that frequently perform reflection-based conversions between objects and maps.
Simplified encapsulation for symmetric, asymmetric, and digest algorithms. Tools for JSON parsing and creation. hutool-extra
Enterprise firewalls or uneven web endpoints often return missing headers. Addressing issue ICB1B8 , Hutool 5.8.39 adds setIgnoreContentLength to the HttpConfig engine. This allows applications to read responses safely, even if a remote proxy strips the Content-Length header:
// 4. Date Offset (Yesterday, Tomorrow, Offset) Date yesterday = DateUtil.yesterday(); Date future = DateUtil.offsetDay(now, 5); // 5 days later
