二维数组的基本遍历方法

import java.util.Arrays;

public class ArraysTest {
    static void arraystest(int[][] arrs) {
        for (int i = 0; i < arrs.length; i++) {
            for (int j = 0; j < arrs[i].length; j++) {
                System.out.print(arrs[i][j] + ",");
            }
            System.out.println(" ");
        }

    }

    public static void main(String[] args) {
        int[][] ars ={{1,2},{4,6},{2,3,4,5}};
        arraystest(ars);
        System.out.println(ars.length);

    }
}
