  - parseMimeType
```
public static MimeType parseMimeType(String mimeType)
```
    Parse the given String into a single MimeType. Recently parsed MimeType are cached for further retrieval.
    参数:
    mimeType - the string to parse
    返回:
    the mime type
    抛出:
    InvalidMimeTypeException - if the string cannot be parsed
  - parseMimeTypes
```
public static List<MimeType> parseMimeTypes(String mimeTypes)
```
    Parse the comma-separated string into a list of MimeType objects.
    参数:
    mimeTypes - the string to parse
    返回:
    the list of mime types
    抛出:
    InvalidMimeTypeException - if the string cannot be parsed
  - tokenize
```
public static List<String> tokenize(String mimeTypes)
```
    Tokenize the given comma-separated string of MimeType objects into a List<String>. Unlike simple tokenization by ",", this method takes into account quoted parameters.
    参数:
    mimeTypes - the string to tokenize
    返回:
    the list of tokens
    从以下版本开始:
    5.1.3
  - toString
```
public static String toString(Collection<? extends MimeType> mimeTypes)
```
    Return a string representation of the given list of MimeType objects.
    参数:
    mimeTypes - the string to parse
    返回:
    the list of mime types
    抛出:
    IllegalArgumentException - if the String cannot be parsed
  - sortBySpecificity
```
public static void sortBySpecificity(List<MimeType> mimeTypes)
```
    Sorts the given list of MimeType objects by specificity.
    Given two mime types:
    if either mime type has a wildcard type, then the mime type without the wildcard is ordered before the other.
    if the two mime types have different types, then they are considered equal and remain their current order.
    if either mime type has a wildcard subtype , then the mime type without the wildcard is sorted before the other.
    if the two mime types have different subtypes, then they are considered equal and remain their current order.
    if the two mime types have a different amount of parameters, then the mime type with the most parameters is ordered before the other.
    For example:
    audio/basic < audio/* < */*
    audio/basic;level=1 < audio/basic
    audio/basic == text/html
    audio/basic == audio/wave
    参数:
    mimeTypes - the list of mime types to be sorted
