What is HostnameVerifier in Java?
Interface HostnameVerifier This class is the base interface for hostname verification.

How to change the default hostname in Java?
Gets the default HostnameVerifier that is inherited by new instances of this class. Sets the HostnameVerifier for this instance. New instances of this class inherit the default static hostname verifier set by setDefaultHostnameVerifier. Calls to this method replace this object’s HostnameVerifier.
Can a hostnameverifier be replaced by a sslsocketfactory?
This class uses HostnameVerifier and SSLSocketFactory . There are default implementations defined for both classes. However, the implementations can be replaced on a per-class (static) or per-instance basis.
Which is the default static sslsocketfactory in Java?
Gets the default HostnameVerifier that is inherited by new instances of this class. Gets the default static SSLSocketFactory that is inherited by new instances of this class. Gets the HostnameVerifier in place on this instance.
What does sslpeerunverifiedexception do in Java SE 11?
SSLPeerUnverifiedException – if the peer is not verified. IllegalStateException – if this method is called before the connection has been established. Returns the server’s principal which was established as part of defining the session. Note: Subclasses should override this method.
