Question

How to split a string into chunks of two characters each in Java

Answer 1

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static List<String> splitStringIntoChunks(String str, int chunkSize) {
        List<String> chunks = new ArrayList<>();
        int length = str.length();

        for (int i = 0; i < length; i += chunkSize) {
            // Extract substring of chunkSize or remaining characters
            chunks.add(str.substring(i, Math.min(i + chunkSize, length)));
        }

        return chunks;
    }

    public static void main(String[] args) {
        String str = "abcdefghijk";
        int chunkSize = 2;

        // Split the string into chunks
        List<String> chunks = splitStringIntoChunks(str, chunkSize);

        System.out.println("Chunks of two characters:");
        for (String chunk : chunks) {
            System.out.println(chunk);
        }
    }
}
