二维数组

举例

输出写法1.

        int[][] array = new int[3][2];
        array[0][0] = 1;
        array[0][1] = 2;
        array[1][0] = 3;
        array[1][1] = 4;
        array[2][0] = 5;
        array[2][1] = 6;
        for (int i = 0; i < array.length; i++) {
        for (int j = 0; j < array[i].length; j++) {

 System.out.println(array[i][j]);

            }
     }

输出写法2.

        int[][] array = {{1,2},{3,4},{5,6}};

        for (int i = 0; i < array.length; i++) {


            for (int j = 0; j < array[i].length; j++) {

                System.out.println(array[i][j]);

            }
        }
