Hey everyone! 🌟 Today, I want to share a technique I found handy for sorting alphanumeric strings in Java. When dealing with mixed data types, the natural sorting order can be quite tricky. Here’s a simple solution I came across.
Key Steps:
1. Regex Patterns: We can split the strings into numbers and non-numbers.
2. Comparator: By using a custom comparator, we can define our sorting logic.
Here's how you can do it:
import java.util.*;
public class AlphanumericSort { public static void main(String[] args) { List<String> items = Arrays.asList("item2", "item10", "item1", "item21"); Collections.sort(items, new AlphanumericComparator()); System.out.println(items); }
static class AlphanumericComparator implements Comparator<String> { public int compare(String s1, String s2) { // Your comparison logic here } } }
Final Thoughts:
- Always consider edge cases, like different lengths of strings. - Using regex might slightly affect performance, so be mindful in large datasets.

Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
The S&P 500 slumped 1.8% on Monday and Tuesday, thanks to China Evergrande, the Chinese property company that looks like it is ready to default on its more-than $300 billion in debt. Cries of the next Lehman Brothers—or maybe the next Silverado?—echoed through the canyons of Wall Street as investors prepared for the worst.
