How does ServerSocket behave in multithreaded code?

The ServerSocket class in Java is utilized for creating server applications that can listen for incoming client connections on a specific port. When implementing ServerSocket in multithreaded environments, it can handle multiple client requests simultaneously. Each client connection is typically managed in its own thread, allowing for concurrent processing, which improves application performance and responsiveness.

When a server accepts a new client connection using accept(), it generally creates a new thread to handle that client. This way, the server can continue to accept other client connections while processing requests from the already connected clients.

However, it's important to handle shared resources correctly to avoid concurrency issues. Synchronization may be required if multiple threads access shared data to ensure thread safety.
