Java數組遍歷的幾種方式

數組遍歷方式參考：

方法一：for循環遍歷

    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遍歷

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

        }

方法三：Arrays工具類中toString (或deepToString)靜態方法遍歷

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