Which classes handle socket operations in Java?

Socket and ServerSocket.

• Socket: Represents a client socket. Used for connecting to a remote host and sending/receiving data.

  // Example of creating a client socket
  try {
      Socket clientSocket = new Socket("localhost", 8080);
      // Further work with input/output streams
  } catch (IOException e) {
      e.printStackTrace();
  }
  

• ServerSocket: Represents a server socket. Used for listening on a specific port on the local host and accepting incoming client connections.

  // Example of creating a server socket
  try {
      ServerSocket serverSocket = new ServerSocket(8080);
      // Waiting for a client to connect
      Socket clientSocket = serverSocket.accept();
      // Further work with input/output streams
  } catch (IOException e) {
      e.printStackTrace();
  }
  

These classes are in the java.net package.
