Java数组遍历的几种方式

方法一：for循环遍历

    public static void main(String[] args) {
        int Arr[][]={{1,2,3},{4,5,6}};
        for (int i = 0; i < Arr.length; i++) {
            for (int j = 0; j < Arr[i].length; j++) {
                System.out.print(Arr[i][j]+" ");
            }
        }
    }


方法二：foreach遍历

        int a[] = {1,2,3,4} ;
        for (int element:a){
            System.out.println(element);

        }

方法三：Arrays工具类中toString (或deepToString)静态方法遍历

        int a[] = {1,2,3,4} ;
        int b[][] = {{3,4},{1,2}};
        System.out.println(Arrays.toString(a));
        System.out.println(Arrays.deepToString(b));
