What are the differences between Java thread pools and threads?

What are the differences between Java thread pools and threads?

Java threads are individual units of execution, while thread pools manage multiple threads for better resource utilization.

Why should I use a thread pool instead of creating new threads?

Thread pools reduce the overhead of thread creation and destruction, improving performance and resource management.

Can you give me an example of how to implement a thread pool in Java?

Sure! You can use the ExecutorService interface to create a thread pool. Here's a simple example:

ExecutorService executor = Executors.newFixedThreadPool(5);
executor.submit(() -> {
    // Task code here
});
executor.shutdown();

What are the potential downsides of using thread pools?

Some downsides include potential resource contention and the complexity of managing tasks, especially in large applications.
