下面关于JSON说法错误的是 A: json是一种数据交互格式 B: json的数据格式有两种为[]和{} C: json数据用{}表示java中的对象[]表示java中的List对象 D: {"1":"123","2":"234","3":"345"}不是json数据

以下程序的输出结果为______。 Dim a%() = {345, -54, 200, 356, 65, 23} Dim i As Integer, m As Integer, intIndex As Integer m = a(intIndex) For i = a.GetLowerBound(0) To a.GetUpperBound(0) If a(i) > m Then m = a(i) intIndex = i End If Next MsgBox(m & " " & intIndex)? 345 ; ;1|-24 ; ;2|356 ; ;4|356 ; ;3

将算式345 + 47改为345 + 74

345

中国大学MOOC: 同样的数字345，八进制，十进制，十六进制中，十进制的345最大。

定义并初始化一个用于存放我们国家的四个直辖市的数组cityName，四个直辖市为：北京，上海，天津，重庆. 正确的是_________ A: String[] cityName=new String[4]{"北京","上海","天津","重庆"}; B: String[] cityName=new String[]{"北京","上海","天津","重庆"}; C: String[] cityName={"北京","上海","天津","重庆"}; D: String cityName = new String[4] { "北京", "上海", "天津", "重庆" };

(345)8 = ( )2 ＝ ( )10= ( )16
