How to create and initialize a 2d array of characters with different row lengths in Java

Answer 1

public class Main {
    public static void main(String[] args) {
         
        char[][] jaggedArray = new char[3][];
         
        // Initialize the rows with different lengths
        jaggedArray[0] = new char[] { 'J', 'a', 'v', 'a' }; 
        jaggedArray[1] = new char[] { 'p', 'r', 'o', 'g', 'r', 'a', 'm', 'm', 'i', 'n', 'g' }; 
        jaggedArray[2] = new char[] { 'l', 'a', 'n', 'g', 'u', 'a', 'g', 'e' };

        int rows = jaggedArray.length;
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < jaggedArray[i].length; j++) {
                System.out.print(jaggedArray[i][j] + " ");
            }
            System.out.println();
        }
    }
}
