Java multidimensional array

-
In Java , a multidimensional array data is stored in row and column based index. In the Java programming language, a multidimensional array is an array whose components are themselves arrays.



 Example :

        class TwoDArrayDemo{
            public static void main(String args[]){

                //declaring and initializing 2D array

                 int arr[][]={{5,10},{15,20}};

              //printing 2D array

              for(int i=0;i<2;i++){   // Row
                     for(int j=0;j<2;j++){   // Column
                            System.out.print("["+i+"]["+j+"] : "+arr[i][j]+"   ");
                            }
                      System.out.println();
           }
       }
   }


 Output :
                [0][0] : 5    [0][1] : 10
                [1][0] : 15  [1][1] : 20
