```
public class MediaType
extends java.lang.Object
implements java.lang.Comparable<MediaType>

    2. if the two media types have different types, then they are considered equal and remain their current order.
    3. if either media type has a wildcard subtype, then the media type without the wildcard is sorted before the other.
    4. if the two media types have different subtypes, then they are considered equal and remain their current order.
    5. if the two media types have different quality value, then the media type with the highest quality value is ordered before the other.
    6. if the two media types have a different amount of parameters, then the media type with the most parameters is ordered before the other.
    For example:
    audio/basic < audio/* < */*
    
    audio/* < audio/*;q=0.7; audio/*;q=0.3
    
    audio/basic;level=1 < audio/basic

    3. if the two media types have different types, then they are considered equal and remain their current order.
    4. if either media type has a wildcard subtype, then the media type without the wildcard is sorted before the other.
    5. if the two media types have different subtypes, then they are considered equal and remain their current order.
    6. if the two media types have a different amount of parameters, then the media type with the most parameters is ordered before the other.
