This is an example of how to create a ServerSocket. 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. Creating a server socket implies that you should: Create a ServerSocket, bound to a specified port. Use accept() API method to ...

In this example we shall show you how to write text to a Socket. To write text to a Socket one should perform the following steps: Get the output stream of the socket, using getOutputStream() API method of Socket. Create an OutputStreamWriter with the socket ouputstream. Create a BufferedWriter that uses a default-sized output buffer. Use write(String str) API method to ...

With this example we are going to demonstrate how to read text from a Socket. A Socket is an endpoint for communication between two machines. In short, to read text from a socket you should: Get the socket input stream, using getInputStream() API method of Socket.

This is an example of how to send an HTTP POST request with a Socket. A socket is an endpoint for communication between two machines. Sending an HTTP POST request using a Socket implies that you should: Get the InetAddress of a specified host, using the host’s name, with getByName(String host) API method of InetAddress. Create a new Socket and connect ...

In this example we shall show you how to create a client Socket with timeout. A client socket is an endpoint for communication between two machines. To create a client socket with timeout one should perform the following steps: Get the InetAddress of a specified host, using the host’s name, with getByName(String host) API method of InetAddress. Create a new ...

With this example we are going to demonstrate how to create a client Socket in Java. In short, to create a socket and connect to a remote server you should : Define the Address of the server socket to connect to Define the specific port the server process running on the remote socket listens to Create a new socket and ...
