二维数组的理解代码

二维数组

public class ArrayDemo05 {
    public static void main(String[] args) {

        int[][] array = {{1,2},{1,3}};
        System.out.println(array[0][1]);

        System.out.println(array.length);
        System.out.println(array[0].length);

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

        }
    }
