JSONArray介绍

[英]A JSONArray is an ordered sequence of values. Its external text form is a string wrapped in square brackets with commas separating the values. The internal form is an object having get and opt methods for accessing the values by index, and put methods for adding or replacing values. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, String, or the JSONObject.NULL object.

The constructor can convert a JSON text into a Java object. The toString method converts to JSON text.

A get method returns a value if one can be found, and throws an exception if one cannot be found. An opt method returns a default value instead of throwing an exception, and so is useful for obtaining optional values.

The generic get() and opt() methods return an object which you can cast or query for type. There are also typed get and opt methods that do type checking and type coersion for you.

The texts produced by the toString methods strictly conform to JSON syntax rules. The constructors are more forgiving in the texts they will accept:

  • An extra , (comma) may appear just before the closing bracket.
  • The null value will be inserted when there is , (comma) elision.
  • Strings may be quoted with ' (single quote).
  • Strings do not need to be quoted at all if they do not begin with a quote or single quote, and if they do not contain leading or trailing spaces, and if they do not contain any of these characters: { } [ ] / \ : , = ; # and if they do not look like numbers and if they are not the reserved words true, false, or null.
  • Values can be separated by ; (semicolon) as well as by , (comma).
  • Numbers may have the 0- (octal) or 0x- (hex) prefix.
  • Comments written in the slashshlash, slashstar, and hash conventions will be ignored.
    [中]JSONArray是一个有序的值序列。它的外部文本形式是一个用方括号括起来的字符串，值之间用逗号分隔。内部表单是一个对象，它具有get和opt方法用于按索引访问值，以及put方法用于添加或替换值。这些值可以是以下任何类型：Boolean、JSONArray、JSONObject、Number、String或JSONObject.NULL object。
    构造函数可以将JSON文本转换为Java对象。toString方法将转换为JSON文本。
    如果可以找到get方法，则返回一个值；如果找不到，则抛出一个异常。opt方法返回默认值而不是引发异常，因此对于获取可选值非常有用。
    泛型get()和opt()方法返回一个对象，您可以强制转换或查询该对象的类型。还有类型化的get和opt方法可以为您进行类型检查和类型协同。
    toString方法生成的文本严格遵守JSON语法规则。构造器在他们将接受的文本中更加宽容：
    *右括号前可能会出现额外的,（逗号）。
    *当存在,（逗号）省略时，将插入null值。
    *字符串可以用'引用（单引号）。
    *如果字符串不以引号或单引号开头，如果字符串不包含前导空格或尾随空格，如果字符串不包含以下任何字符：[21$]]，如果字符串看起来不像数字，如果字符串不是保留字true、false或null，则根本不需要引用字符串。
    *值可以用;（分号）和,（逗号）分隔。
    *数字可以有0-（八进制）或0x-（十六进制）前缀。
    *以slashshlash、slashstar和哈希约定编写的注释将被忽略。
