The java.net.UnknownHostException is an exception class in Java that is thrown when a program attempts to create a connection to a remote host using its hostname or IP address, but the hostname or IP address cannot be resolved. This exception typically occurs when there is a problem with the DNS (Domain Name System) server or when the hostname is misspelled. It serves as an indication that the host being accessed is not known or cannot be reached by the network.
