## Class ContentType

- java.lang.Object
- - org.apache.hc.core5.http.ContentType

- All Implemented Interfaces:
    Serializable

      @Contract(threading=IMMUTABLE)
      public final class ContentType
      extends Object
      implements Serializable

  Content type information consisting of a MIME type and an optional charset.

  This class makes no attempts to verify validity of the MIME type. The input parameters of the `create(String, String)` method, however, may not contain characters `<">, <;>, <,>` reserved by the HTTP specification.
