# Sockets
There are multiple classes implementing socket behavior in JeroMQ.
## tl;dr: How do I construct a Socket?
Use [ZContext.createSocket][create-socket]. This returns a
[ZMQ.Socket][zmq-socket].
## zmq.SocketBase
[zmq.SocketBase][socket-base] contains low-level implementation details of
ZeroMQ socket behavior.
It should not be used directly in code that uses the JeroMQ library.
## org.zeromq.ZMQ.Socket
[ZMQ.Socket][zmq-socket] is the user-facing API for working with sockets in
JeroMQ.
Sockets are constructed by calling [ZContext.createSocket][create-socket]. This
is essential because it registers the poller with the context, so that when the
context is closed, the poller and selector resources are cleaned up properly.
