Java多维数组

public class multiarraysExample1
{
	public static void main(String[] args)
	{
		int[][] magicSquare =
			{
				{16,3,2,13},
				{5,10,11,8},
				{9,6,7,12 },
				{4,15,14,1}
			};
		
		for (int i = 0; i < magicSquare[0].length; i++)
			{
				System.out.printf("%d
", magicSquare[0][i]);
			}

		for (int i = 0; i< magicSquare.length; i++)
		{
			for (int j = 0; j< magicSquare[i].length; j++)
			{
				System.out.printf("%d
", magicSquare[i][j]);
			}
		}

		for(int[] row: magicSquare)// loop through the rows first
		{
			for(int value : row) // loop through the elements of the row
				System.out.printf("%d
", value);
		}
	}

}

To print out a quick-and-dirty list of the elements of a two-dimensional array, call:

System.out.println(Arrays.deepToString(magicSquare)); // print out a quick-and-dirty
