What is Java concurrency and how can I implement it?

Java concurrency is the ability of a program to execute multiple threads simultaneously. You can implement it using the Thread class or the Runnable interface.

Can you explain the difference between synchronized and volatile?

Yes! synchronized 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.

What are some common concurrency issues I should be aware of?

Common issues include race conditions, deadlocks, and thread starvation. It's important to design your code to avoid these problems.

How can I use the Executor framework for managing threads?

The Executor framework provides a higher-level replacement for managing threads. You can use Executors.newFixedThreadPool() to create a pool of threads for executing tasks.
