multi dimensional array declaration in java code example

Example 1: Multidimensional array in java

// two dimensional array in java example program
public class SimpleTwodimensionalArray
{
   public static void main(String[] args) 
   {
      // declare and initialize two dimensional array
      int[][] arrnumbers = {{2, 4},{6, 8},{10, 12}};   
      System.out.println("Two dimensional array in java: ");    
      for(int a = 0; a < 3; a++) 
      {
         for(int b = 0; b < 2; b++) 
         {
            System.out.println(arrnumbers[a][b]);
         }
      }
   }
}

Example 2: two dimensional array in java example program

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

        int[][] a = {
            {1, -2, 3}, 
            {-4, -5, 6, 9}, 
            {7}, 
        };
      
        for (int i = 0; i < a.length; ++i) {
            for(int j = 0; j < a[i].length; ++j) {
                System.out.println(a[i][j]);
            }
        }
    }
}

Example 3: two dimensional array in java example program

String[][][] data = new String[3][4][2];
