    Demo: JSON 表示一个数字
    2.90

    Demo: JSON 表示一个字符串
    "Hello world"

    Demo: JSON 表示一个对象
    {
      "name":"smith".
      "age":30,
      "sex":"男"
    }

    Demo: JSON对象的属性可以是对象
    {
      "name":"smith".
      "age":28,
      "sex":"男"
      "school":{
      "sname":"南京大学".
      "address":"南京市鼓楼区汉口路22号"
    }
    }

    Demo: JSON 格式表示数组
    保存名字的数组: ["张三","李四","王五"]
    保存雇员的信息: ["smith",1001,"clerck",7788,2000.00,200.0]
    [
      ["smith",1001,"clerck",7788,2000.00,200.0]
      ["smith",1001,"clerck",7788,2000.00,200.0]
      ["smith",1001,"clerck",7788,2000.00,200.0]
    ]
    [
      {"name":"smith","empno":1001,"job":"clerck","sal":9000.00,"comm":5000.00},
      {"name":"smith","empno":1001,"job":"clerck","sal":9000.00,"comm":5000.00},
      {"name":"smith","empno":1001,"job":"clerck","sal":9000.00,"comm":5000.00},
    ]

    Demo: 对象数组
    在一个数组保存多个 json 对象 (在一个数组中保存多个对象)
    [
      {
        "title":"Java 开发",
        "edition":3,
        "author":["smith","张三","李四"]
      },
      {
        "title":"Web 开发",
        "edition":3,
        "author":["Allen","王五","赵六"]
      }
    ]
    二维数组保存
    [
      ["Java 开发",3,["smith","张三","李四"]],
      ["Web 开发",3["Allen","王五","赵六"]]
    ]
