What is the difference between socket and ServerSocket?
Here, two classes are being used: Socket and ServerSocket. The Socket class is used to communicate client and server. Through this class, we can read and write message. The ServerSocket class is used at server-side.
What is SocketAddress?
The combination of an IP address and a port number is called a socket address. The client socket address defines the client process uniquely just as the server socket address defines the server process uniquely as shown in Figure.
What is a common in socket and ServerSocket?
Socket class represents a socket, and the java. net. ServerSocket class provides a mechanism for the server program to listen for clients and establish connections with them. The constructor of the Socket class attempts to connect the client to the specified server and the port number.
What does .accept do in java?
Create a server with the specified port, listen backlog, and local IP address to bind to. The bindAddr argument can be used on a multi-homed host for a ServerSocket that will only accept connect requests to one of its addresses.
Which method is used to close the socket?
Java ServerSocket close() method. The close() method of ServerSocket class is used to close this socket. Any thread currently blocked in accept() will throw a SocketException. The associated channel is also closed by it if it has any.
What does accept () do in java?
The accept() method of ServerSocket class is used to accept the incoming request to the socket. To complete the request, the security manager checks the host address, port number, and localport.
What’s the difference between socket and serversocket in Java?
java.net.ServerSocket This class implements server sockets. A server socket waits for requests to come in over the network. It performs some operation based on that request, and then possibly returns a result to the requester.
How does serversocket create an unbound server socket?
ServerSocket() Creates an unbound server socket. ServerSocket(int port) Creates a server socket, bound to the specified port. ServerSocket(int port, int backlog) Creates a server socket and binds it to the specified local port number, with the specified backlog.
How does serversocket bind to a specific address?
Binds the ServerSocket to a specific address (IP address and port number). If the address is null, then the system will pick up an ephemeral port and a valid local address to bind the socket. The backlog argument is the requested maximum number of pending connections on the socket. Its exact semantics are implementation specific.
What’s the difference between a server and a serverocket?
The server features includes listening to the port and accepting an incoming connection etc… ServerSocket is created to bind to a port and listen for a connect from a client. So, a server just waits for a conversation and doesn’t start one.
