  • Where datatype Type of data to be stored in the array. For example int, char, etc.
  • Dimension: The dimension of the array created.
  • For example : 1D, 2D, etc

Example :

/* JAVA program to understand multidimensional array */
/* www.codewindow.in */

import java.util.*;
public class codewindow_one
{
    public static void main(String args[])
    {
        int arr[][]=new int[4][4];
        int count=1;
        for(int i=0; i<4; i++)
        {
            for(int j=0; j<4; j++)
            {
                arr[i][j]=count++;
            }
        }
        for(int i=0; i<4; i++)
        {
            for(int j=0; j<4; j++)
            {
                System.out.print(arr[i][j]+" ");
            }
            System.out.println();
        }
    }
}
