对于代码:

// Demonstrate a two-dimensional array.
class TwoDArray {
    public static void main(String args[]) {
        int twoD[][] = new int[4][5];
        int i, j, k = 0;
        for (i = 0; i < 4; i++)
            for (j = 0; j < 5; j++) {
                twoD[i][j] = k;
                k++;
            }
        for (i = 0; i < 4; i++) {
            for (j = 0; j < 5; j++)
                System.out.print(twoD[i][j] + " ");
                System.out.println();
        }
    }    
}

输出给了我:
