    //from  w  w  w. ja va  2s. c om
    // Populate the ragged array using for loops
    for(int i = 0; i < ra.length; i++) {
      for(int j = 0; j < ra[i].length; j++){
        ra[i][j] = i + j;
      }
    }

    // Print the array using for loops
    for(int i = 0; i < ra.length; i++) {
      for (int j = 0; j < ra[i].length; j++){
        System.out.print(ra[i][j] + "\t");
      }

      // Add a new line after each row is printed
