JAVA中JSON数组

1：JSON 对象中的数组

{
"name":"网站",
"num":3,
"sites":[ "Google", "Runoob", "Taobao" ]
}

x = myObj.sites[0];

2：循环数组

for (i in myObj.sites) {
    x += myObj.sites[i] + "<br>";
}

3嵌套 JSON 对象中的数组

myObj = {
    "name":"网站",
    "num":3,
    "sites": [
        { "name":"Google", "info":[ "Android", "Google 搜索", "Google 翻译" ] },
        { "name":"Runoob", "info":[ "菜鸟教程", "菜鸟工具", "菜鸟微信" ] },
        { "name":"Taobao", "info":[ "淘宝", "网购" ] }
    ]
}

for (i in myObj.sites) {
    x += "<h1>" + myObj.sites[i].name + "</h1>";
    for (j in myObj.sites[i].info) {
        x += myObj.sites[i].info[j] + "<br>";
    }
}
