public MediaType()
```
    Creates a new instance of MediaType, both type and subtype are wildcards. Consider using the constant WILDCARD_TYPE instead.
- Method Detail
  - valueOf
```
public static MediaType valueOf(String type)
```
    Creates a new instance of MediaType by parsing the supplied string.
    
    Parameters:
    
    type - the media type string.
    
    Returns:
    
    the newly created MediaType.
    
    Throws:
    
    IllegalArgumentException - if the supplied string cannot be parsed or is null.
  - getType
```
public String getType()
```
    Getter for primary type.
    
    Returns:
    
    value of primary type.
  - isWildcardType
```
public boolean isWildcardType()
```
    Checks if the primary type is a wildcard.
    
    Returns:
    
    true if the primary type is a wildcard.
  - getSubtype
```
public String getSubtype()
```
    Getter for subtype.
    
    Returns:
    
    value of subtype.
  - isWildcardSubtype
```
public boolean isWildcardSubtype()
```
    Checks if the subtype is a wildcard.
    
    Returns:
    
    true if the subtype is a wildcard.
  - getParameters
```
public Map<String,String> getParameters()
```
    Getter for a read-only parameter map. Keys are case-insensitive.
    
    Returns:
    
    an immutable map of parameters.
  - withCharset
```
public MediaType withCharset(String charset)
```
    Create a new MediaType instance with the same type, subtype and parameters copied from the original instance and the supplied "charset" parameter.
    
    Parameters:
    
    charset - the "charset" parameter value. If null or empty the "charset" parameter will not be set or updated.
    
    Returns:
    
    copy of the current MediaType instance with the "charset" parameter set to the supplied value.
    
    Since:
    
    2.0
  - isCompatible
```
public boolean isCompatible(MediaType other)
```
    Check if this media type is compatible with another media type. E.g. image/* is compatible with image/jpeg, image/png, etc. Media type parameters are ignored. The function is commutative.
    
    Parameters:
    
    other - the media type to compare with.
    
    Returns:
    
    true if the types are compatible, false otherwise.
  - equals
```
public boolean equals(Object obj)
```
    Compares obj to this media type to see if they are the same by comparing type, subtype and parameters. Note that the case-sensitivity of parameter values is dependent on the semantics of the parameter name, see HTTP/1.1. This method assumes that values are case-sensitive.
    Note that the equals(...) implementation does not perform a class equality check (this.getClass() == obj.getClass()). Therefore any class that extends from MediaType class and needs to override one of the equals(...) and hashCode() methods must always override both methods to ensure the contract between Object.equals(java.lang.Object) and Object.hashCode() does not break.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object to compare to.
    
    Returns:
    
    true if the two media types are the same, false otherwise.
  - hashCode
```
public int hashCode()
```
    Generate a hash code from the type, subtype and parameters.
    Note that the equals(java.lang.Object) implementation does not perform a class equality check (this.getClass() == obj.getClass()). Therefore any class that extends from MediaType class and needs to override one of the equals(Object) and hashCode() methods must always override both methods to ensure the contract between Object.equals(java.lang.Object) and Object.hashCode() does not break.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a generated hash code.
  - toString
```
public String toString()
```
    Convert the media type to a string suitable for use as the value of a corresponding HTTP header.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string version of the media type.
