How to Split a String at Every N-th Character in Java?

Splitting Strings at Every N-th Character

In programming, it is often necessary to split a string into individual characters or substrings. JavaScript provides a convenient way to split a string at every n-th character using the .match() method. However, in Java, achieving the same result requires a slightly different approach.

Java Solution

To split a string at every n-th character in Java, you can utilize the following code:

String s = "1234567890";
System.out.println(java.util.Arrays.toString(s.split("(?<=\G...)")));

This code employs the following techniques:

• Split() Method: Divides the string into substrings based on a given delimiter.
• Regular Expression: The delimiter uses a regular expression to define the splitting criteria.
• (?<=G...) Regex: Captures an empty string that matches the previous match followed by three characters.

This allows you to split the string "1234567890" into the following substrings:

[123, 456, 789, 0]

The resulting list of substrings accurately reflects the desired splitting into 3-character segments.
