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.

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
Why Telegram?
Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
