What are some tips for effective Java threading?

Here are a few tips for effective Java threading: 1. Use the Executor framework for managing threads. 2. Avoid using Thread.sleep() for timing; instead, use ScheduledExecutorService. 3. Be cautious with shared resources and use synchronization to prevent race conditions.

Can you explain the Executor framework?

The Executor framework provides a higher-level replacement for managing threads. It allows you to decouple task submission from the mechanics of how each task will be run, making it easier to manage thread pools and asynchronous task execution.

What are race conditions and how can I avoid them?

Race conditions occur when multiple threads access shared data and try to change it at the same time. To avoid them, use synchronization mechanisms like synchronized blocks or locks to ensure that only one thread can access the shared resource at a time.

What is the difference between synchronized and volatile?

The 'synchronized' keyword ensures that only one thread can access a block of code at a time, while 'volatile' ensures that changes to a variable are visible to all threads immediately, but it does not provide mutual exclusion.
