public final class MediaType
extends Object
```
Represents an Internet Media Type (also known as a MIME Type or Content Type). This class also supports the concept of media ranges defined by HTTP/1.1. As such, the * character is treated as a wildcard and is used to represent any acceptable type or subtype value. A media type may not have wildcard type with a declared subtype. The * character has no special meaning as part of a parameter. All values for type, subtype, parameter attributes or parameter values must be valid according to RFCs 2045 and 2046.
All portions of the media type that are case-insensitive (type, subtype, parameter attributes) are normalized to lowercase. The value of the charset parameter is normalized to lowercase, but all others are left as-is.
Note that this specifically does not represent the value of the MIME Content-Type header and as such has no support for header-specific considerations such as line folding and comments.
For media types that take a charset the predefined constants default to UTF-8 and have a "_UTF_8" suffix. To get a version without a character set, use withoutParameters().

  - ZIP
```
public static final MediaType ZIP
```
- Method Detail
  - type
```
public String type()
```
    Returns the top-level media type. For example, "text" in "text/plain".
  - subtype
```
public String subtype()
```
    Returns the media subtype. For example, "plain" in "text/plain".
  - parameters
```
public ImmutableListMultimap<String,String> parameters()
```
    Returns a multimap containing the parameters of this media type.
  - charset
```
public Optional<Charset> charset()
```
    Returns an optional charset for the value of the charset parameter if it is specified.
    
    Throws:
    
    IllegalStateException - if multiple charset values have been set for this media type
    
    IllegalCharsetNameException - if a charset value is present, but illegal
    
    UnsupportedCharsetException - if a charset value is present, but no support is available in this instance of the Java virtual machine
  - withoutParameters
```
public MediaType withoutParameters()
```
    Returns a new instance with the same type and subtype as this instance, but without any parameters.
  - withParameters
```
public MediaType withParameters(Multimap<String,String> parameters)
```
    Replaces all parameters with the given parameters.
    
    Throws:
    
    IllegalArgumentException - if any parameter or value is invalid
  - withParameter
```
public MediaType withParameter(String attribute,
                      String value)
```
    Replaces all parameters with the given attribute with a single parameter with the given value. If multiple parameters with the same attributes are necessary use withParameters(com.google.common.collect.Multimap<java.lang.String, java.lang.String>). Prefer withCharset(java.nio.charset.Charset) for setting the charset parameter when using a Charset object.
    
    Throws:
    
    IllegalArgumentException - if either attribute or value is invalid
  - withCharset
```
public MediaType withCharset(Charset charset)
```
    Returns a new instance with the same type and subtype as this instance, with the charset parameter set to the name of the given charset. Only one charset parameter will be present on the new instance regardless of the number set on this one.
    If a charset must be specified that is not supported on this JVM (and thus is not representable as a Charset instance, use withParameter(java.lang.String, java.lang.String).
  - hasWildcard
```
public boolean hasWildcard()
```
    Returns true if either the type or subtype is the wildcard.
  - is
```
public boolean is(MediaType mediaTypeRange)
```
    Returns true if this instance falls within the range (as defined by the HTTP Accept header) given by the argument according to three criteria:
    1. The type of the argument is the wildcard or equal to the type of this instance.
    2. The subtype of the argument is the wildcard or equal to the subtype of this instance.
    3. All of the parameters present in the argument are present in this instance.
    For example:
```
   PLAIN_TEXT_UTF_8.is(PLAIN_TEXT_UTF_8) // true
   PLAIN_TEXT_UTF_8.is(HTML_UTF_8) // false
   PLAIN_TEXT_UTF_8.is(ANY_TYPE) // true
   PLAIN_TEXT_UTF_8.is(ANY_TEXT_TYPE) // true
   PLAIN_TEXT_UTF_8.is(ANY_IMAGE_TYPE) // false
   PLAIN_TEXT_UTF_8.is(ANY_TEXT_TYPE.withCharset(UTF_8)) // true
   PLAIN_TEXT_UTF_8.withoutParameters().is(ANY_TEXT_TYPE.withCharset(UTF_8)) // false
   PLAIN_TEXT_UTF_8.is(ANY_TEXT_TYPE.withCharset(UTF_16)) // false
```
    Note that while it is possible to have the same parameter declared multiple times within a media type this method does not consider the number of occurrences of a parameter. For example, "text/plain; charset=UTF-8" satisfies "text/plain; charset=UTF-8; charset=UTF-8".
  - create
```
public static MediaType create(String type,
               String subtype)
```
    Creates a new media type with the given type and subtype.
    
    Throws:
    
    IllegalArgumentException - if type or subtype is invalid or if a wildcard is used for the type, but not the subtype.
  - parse
```
public static MediaType parse(String input)
```
    Parses a media type from its string representation.
    
    Throws:
    
    IllegalArgumentException - if the input is not parsable
  - equals
```
public boolean equals(@Nullable
             Object obj)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Returns the string representation of this media type in the format described in RFC 2045.
    
    Overrides:
    
    toString in class Object
