How do I send an image to a socket?

Send image to client over a socket

  1. Send different image type, e.g. png, gif – worked;
  2. Save the jpg file as a png and send it over – worked;
  3. Write a simple program that copies a jpg image from one location to another – worked;
  4. Send the image in actual size to the client – worked.

How do I connect a socket in Java?

  1. Create and open a server socket. View. ServerSocket serverSocket = new ServerSocket(portNumber);
  2. Wait for the client request. View.
  3. Create input and output streams to the socket. View.
  4. Communicate with the client. Receive data from the client: (inputLine = in.readLine() )
  5. Close the stream, and then close the socket.

How do you handle multiple clients in socket programming in Java?

Because threading in Java is reasonably straightforward, making a server that handles multiple clients is relatively easy. The basic scheme is to make a single ServerSocket in the server and call accept( ) to wait for a new connection.

What is socket in Java with example?

Java Socket programming is used for communication between the applications running on different JRE. Java Socket programming can be connection-oriented or connection-less. The client in socket programming must know two information: IP Address of Server, and. Port number.

How does socket programming work in Java?

A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.

How do you send data into a socket?

One easy way to send this over the socket is to use DataOutputStream/DataInputStream : Client: Socket socket = …; // Create and connect the socket DataOutputStream dOut = new DataOutputStream(socket. getOutputStream()); // Send first message dOut.

Can multiple clients connect to same socket Java?

java. You can either copy the client program in two three separate files and run them individually, or if you have an IDE like eclipse, run multiple instances from the same program. The output shown above is from a single client program, the similar results will be achieved if multiple clients are used.

Can two threads use the same socket?

You are rather safe. No two threads can use the same Socket because of the Synchronize sections. So they’re never mutating it at the same time. However you’re not free of deadlocks, and you may very well end up with many threads waiting for the sync on the same Socket, when others are available.

Why do we need socket programming?

Sockets allow you to exchange information between processes on the same machine or across a network, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP.
