I'm in the process of writing a piece of code that connects to a server spawns a bunch of threads using that connection and does a bunch of "stuff".
There are certain instances where the connection fails and I need to stop everything and start from scratch with a new object.
I wanted to clean up after the object but calling thread.stop on the threads, but this method is seemingly deprecated.
What is the recommended alternative to doing this? Should I write my own cleanup and exit method for each of the threads? Set the thread to null? or something else?

Whenever we want to stop a thread from running state by calling stop() method of Thread class in Java. This method stops the execution of a running thread and removes it from the waiting threads pool and garbage collected.
interrupt() method: If any thread is in sleeping or waiting for a state then using the interrupt() method, we can interrupt the execution of that thread by showing InterruptedException. A thread that is in the sleeping or waiting state can be interrupted with the help of the interrupt() method of Thread class.
Modern ways to suspend/stop a thread are by using a boolean flag and Thread. interrupt() method. Using a boolean flag: We can define a boolean variable which is used for stopping/killing threads say 'exit'. Whenever we want to stop a thread, the 'exit' variable will be set to true.
The only way to stop a thread asynchronously is the stop() method.
Assuming your threads are reasonably under your control - i.e. they're not calling anything which is going to potentially wait forever without your code executing - I would shut it down with a simple (but thread-safe - use volatile!) flag.
See this article for an example in C# - the Java equivalent should be easy to work out. Calling interrupt won't have any effect until the thread next waits, and stop can leave your app in a hard-to-predict state. Wherever possible, go for a clean, orderly shutdown instead.

Use your_thread.interrupt and check in your thread if Thread.interrupted() return true. If so, close your thread properly.
