Sorting Alphanumeric Strings in Java

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.

Give it a try, and let me know how it goes! 💻✨
