create a 2 dimensional array in java code example

Example 1: Multidimensional array in java

// two dimensional string array in java example
public class TwoDimensionalStringArray 
{
   public static void main(String[] args) 
   {
      String[][] animals = {
              { "Lion", "Tiger", "Cheetah" },
              { "Deer", "Jackal", "Bear" },
              { "Hyena", "Fox", "Elephant" } };
      for(int a = 0; a < animals.length; a++) 
      {
         System.out.print(animals[a][0] + " ");
         for(int b = 1; b < animals[a].length; b++) 
         {
            System.out.print(animals[a][b] + " ");
         }
         System.out.println();
      }
   }
}

      {
         for(int b = 0; b < 3; b++)
         {
            arrNumbers[a][b] = (int) (Math.random() * 6) ;
         }
      }
      for(int x = 0; x < 3; x++)
      {
         for(int y = 0; y < 3; y++)
         {
            System.out.print(arrNumbers[x][y] + " ");
         }
