抛出JSONException的com.xiaoleilu.hutool.json中的方法

限定符和类型	方法和说明
JSONObject	JSONObject.accumulate(String key, Object value) 积累值。
JSONObject	JSONObject.append(String key, Object value) 追加值，如果key无对应值，就添加一个JSONArray，其元素只有value，如果值已经是一个JSONArray，则添加到值JSONArray中。
void	JSONTokener.back() 将标记回退到第一个字符，重新开始解析新的JSON
JSONObject	JSONObject.increment(String key) 对值加一，如果值不存在，赋值1，如果为数字类型，做加一操作
String	JSONArray.join(String separator) Make a string from the contents of this JSONArray.
boolean	JSONTokener.more() 源字符串是否有更多的字符
char	JSONTokener.next() 获得源字符串中的下一个字符
char	JSONTokener.next(char c) 读取下一个字符，并比对是否和指定字符匹配
String	JSONTokener.next(int n) 获得接下来的n个字符
String	XMLTokener.nextCDATA() Get the text in the CDATA block.
char	JSONTokener.nextClean() 获得下一个字符，跳过空白符
Object	XMLTokener.nextContent() Get the next XML outer token, trimming whitespace.
Object	XMLTokener.nextEntity(char ampersand) Return the next entity.
Object	XMLTokener.nextMeta() Returns the next XML meta token.
String	JSONTokener.nextString(char quote) 返回当前位置到指定引号前的所有字符，反斜杠的转义符也会被处理。
String	JSONTokener.nextTo(char delimiter) Get the text up but not including the specified character or the end of line, whichever comes first.
String	JSONTokener.nextTo(String delimiters) Get the text up but not including one of the specified delimiter characters or the end of line, whichever comes first.
Object	XMLTokener.nextToken() Get the next XML Token.
Object	JSONTokener.nextValue() 获得下一个值，值类型可以是Boolean, Double, Integer, JSONArray, JSONObject, Long, or String, or the JSONObject.NULL
static void	XML.noSpace(String string) Throw an exception if the string contains whitespace.
protected static String	JSONUtil.numberToString(Number number) Produce a string from a Number.
JSONArray	JSONArray.put(int index, Object value) 加入或者替换JSONArray中指定Index的值，如果index大于JSONArray的长度，将在指定index设置值，之前的位置填充JSONNull.Null
JSONObject	JSONObject.put(String key, Object value) PUT 键值对到JSONObject中，如果值为null，将此键移除
JSONObject	JSONObject.putOnce(String key, Object value) Put a key/value pair in the JSONObject, but only if the key and the value are both non-null, and only if there is not already a member with that name.
JSONObject	JSONObject.putOpt(String key, Object value) 在键和值都为非空的情况下put到JSONObject中
boolean	XMLTokener.skipPast(String to) Skip characters until past the requested string.
char	JSONTokener.skipTo(char to) Skip characters until the next character is the requested character.
protected static void	JSONUtil.testValidity(Object obj) 如果对象是Number 且是 NaN or infinite，将抛出异常
JSONArray	JSONObject.toJSONArray(Collection<String> names) 将指定KEY列表的值组成新的JSONArray
JSONObject	JSONArray.toJSONObject(JSONArray names) Produce a JSONObject by combining a JSONArray of names with the values of this JSONArray.
static JSONObject	XML.toJSONObject(String string) Convert a well-formed (but not necessarily valid) XML string into a JSONObject.
static JSONObject	XML.toJSONObject(String string, boolean keepStrings) Convert a well-formed (but not necessarily valid) XML string into a JSONObject.
String	JSONObject.toJSONString(int indentFactor) Make a prettyprinted JSON text of this JSONObject.
String	JSONArray.toJSONString(int indentFactor) Make a prettyprinted JSON text of this JSONArray.
String	JSON.toJSONString(int indentFactor) 转换为JSON字符串
static String	XML.toString(Object object) Convert a JSONObject into a well-formed, element-normal XML string.
static String	XML.toString(Object object, String tagName) Convert a JSONObject into a well-formed, element-normal XML string.
protected static String	JSONUtil.valueToString(Object value) Make a JSON text of an Object value.
Writer	JSONObject.write(Writer writer)
Writer	JSONArray.write(Writer writer)
Writer	JSON.write(Writer writer) 将JSON内容写入Writer，无缩进 Warning: This method assumes that the data structure is acyclical.
Writer	JSONObject.write(Writer writer, int indentFactor, int indent)
Writer	JSONArray.write(Writer writer, int indentFactor, int indent)
Writer	JSON.write(Writer writer, int indentFactor, int indent) 将JSON内容写入Writer Warning: This method assumes that the data structure is acyclical.
protected static Writer	JSONUtil.writeValue(Writer writer, Object value, int indentFactor, int indent) 写入值到Writer
