body: <p>I am new to WebSockets.</p>
  
  <p>I have already made a simple server-client chat in WebSockets.</p>
  
  <p>And now I am trying to make client-server-client chat application.</p>
  
  <p>I have a question that in java server how can we send a message to particular WebSocket connection.</p>
  
  <p>If user-A want to send a message to User-B.</p>
  
  <p>Then how can I manage that User-B is using this or that connection or send a message to that particular connection?</p>
