Question about the task

Creating a multi-array

Java Syntax, Level 6, Lesson 6

Resolved

I have displayed all numbers in multiArray..but the result that I am stuck with last point

package en.codegym.task.pro.task05.task0512; /* Creating a multi-array */ public class Solution { public static int[][][] multiArray = new int[][][]{{{4, 8, 15}, {16}}, {{23, 42}, {}}, {{1}, {2}, {3}, {4, 5}}}; public static void main(String[] args) { //write your code here multiArray = new int [][][] {{{4, 8, 15}, {16}}, {{23, 42}, {}}, {{1}, {2}, {3}, {4, 5}}} ; for(int i=0; i<multiArray.length;i++) { for(int j=0;j<multiArray[i].length;j++) { for(int k=0;k<multiArray[i][j].length ;k++) { System.out.println(multiArray[i][j][k]) ; } System.out.println () ; } System.out.println () ; } System.out.println () ; } }

1. have you tried to use the array defined by codegym (delete lines 13 - 15) 2 .I don not know the task... but have you tried to not print empty lines (remove lines 26, 28, 30) Just some note2: - you can format the array definition so that you can see what is going on - if you don't need to change any values, you can use a for-each loop.

public static int[][][] multiArray = new int[][][]
        {
                {
                        {4, 8, 15},
                        {16}
                },
                {
                        {23, 42},
                        {}
                },
                {
                        {1},
                        {2},
                        {3},
                        {4, 5}
                }
        };

public static void main(String[] args) {
    for (int[][] dim2 : multiArray) // loop over 3dim-array (multi-array) and get all elements -> 2dim arrays
        for (int[] dim1 : dim2) // loop over 2dim-array and get all elements -> arrays
            for (int cell : dim1) // loop over the inner arrays and get each cell
                System.out.println(cell);

What @Thomas wrote for the predefined CG array is important. In terms of the system.out.println() statements, make use of the "Run" option of the Editor to evaluate the output (just deleting all might not be always the right choice :)).
