How to Keep Track of Number of Threads or Connections
by DevX Pro
I have a server application listening for client applets to connect. The server spawns a new thread each time a connection to a client is established. I want to keep track, i.e. count the number of clients connected and output it to a textfield in a frame. I am not sure how Java handles shared data among threads so my question is: How does one keep track of the number of threads or connections? I want the number of threads to be displayed in a single frame; I tried something, but a new window is created each time a new thread is spawned.

What am I missing?
