Another example: Enhanced File reading with new methods in FileUtil that read all lines and filter them, or write lines with encoding specified.
Need to mention that in the guide. Also, if there's a new way to handle system properties or environment variables, that could be part of the new features.
import cn.hutool.core.io.FileUtil;
Map<String, Object> map = new HashMap<>(); map.put("user.name", "Alice"); map.put("user.age", 30);
Check for other possible features. Maybe they improved the HttpUtil for asynchronous requests or better error handling. Or added new data structure utilities, like a custom List implementation. hutool 39 new
I should also mention migration from previous versions if there are breaking changes. But since the user didn't specify, I can note that it's a backward-compatible update with minimal breaking changes, and provide any necessary tips for upgrading.
Date date = DateUtil.parseIso8601("2023-10-10T12:30:45Z"); System.out.println(DateUtil.format(date, "yyyy-MM-dd HH:mm:ss")); Another example: Enhanced File reading with new methods
Including code examples for each point will make the guide practical. Each example should be a small, self-contained snippet that demonstrates the usage.
Let me structure the guide accordingly, making sure each new feature is explained with context and examples. Also, highlight the benefits these features bring to developers. import cn
