ServerSocketChannel in Java
In Java network programming, ServerSocketChannel
is a class that provides a way to listen for incoming TCP connections from clients. It is a type of SelectableChannel
that can be used for non-blocking I/O operations, which allows the application to perform other tasks while waiting for incoming connections.
To create a ServerSocketChannel
, you can call the open()
method on the ServerSocketChannel
class:
ServerSocketChannel serverSocketChannel = ServerSocketChannel.open();
You can then bind the ServerSocketChannel
to a local address and port using the bind()
method:
serverSocketChannel.bind(new InetSocketAddress("localhost", 8080));
Once the ServerSocketChannel
is bound, you can accept incoming connections using the accept()
method:
SocketChannel clientSocketChannel = serverSocketChannel.accept();
The accept()
method returns a SocketChannel
that can be used to communicate with the client.
You can also configure the ServerSocketChannel
to be non-blocking using the configureBlocking()
method:
