数组中的Java数组

import java.util.Arrays;



public class ArrayWithinAnArray{

   public static void main(String args[]) {

      int[] myArray1 = {23, 56, 78, 91};

      int[] myArray2 = {123, 156, 178, 191};

      int[] myArray3 = {223, 256, 278, 291};

      int[] myArray4 = {323, 356, 378, 391};

      int [][] arrayOfArrays = {myArray1, myArray2, myArray3, myArray4};

      System.out.println(Arrays.deepToString(arrayOfArrays));

   }

}
