+# Java Tutorial: Multidimensional Arrays in Java
+- Multidimensional Arrays are an Array of Arrays. Each elements of an M-D array is an array itself. Marks in the previous example was a 1-D array.
+
+### Multidimensional 2-D Array
+- A 2-D array can be created as follows:
+
+      int [][] flats = new int[2][3]          //A 2-D array of 2 rows + 3 columns
+      
+- We can add elements to this array as follows
+
+      flats[0][0] = 100
+      flats[0][1] = 101
+      flats[0][2] = 102
+      // … & so on!
+      
+- This 2-D array can be visualized as follows:

+
+- Similarly, a 3-D array can be created as follows:
+
+      String[][][] arr = new String [2][3][4]
+      
+### Code as Described in the Video
+
+```
+package com.company;
+
+public class cwh_28_multi_dim_arrays {
+    public static void main(String[] args) {
+        int [] marks; // A 1-D Array
+        int [][] flats; // A 2-D Array
+        flats = new int [2][3];
+        flats[0][0] = 101;
+        flats[0][1] = 102;
+        flats[0][2] = 103;
+        flats[1][0] = 201;
+        flats[1][1] = 202;
+        flats[1][2] = 203;
+
+        // Displaying the 2-D Array (for loop)
+        System.out.println("Printing a 2-D array using for loop");
+        for(int i=0;i<flats.length;i++){
+            for(int j=0;j<flats[i].length;j++) {
+                System.out.print(flats[i][j]);
+                System.out.print(" ");
+            }
+            System.out.println("");
+        }
+
+    }
+}
