What is the difference between concurrency and multithreading in Java?

Concurrency refers to the ability of a program to manage multiple tasks at the same time, while multithreading is a specific implementation of concurrency that allows multiple threads to run within a single process.

Can you explain how multithreading works in Java?

In Java, multithreading is achieved by creating multiple threads using the Thread class or implementing the Runnable interface. Each thread can run independently, allowing for parallel execution of tasks.

What are some advantages of using concurrency in Java?

Some advantages include improved application performance, better resource utilization, and the ability to handle multiple tasks simultaneously, which can lead to a more responsive user experience.

Are there any challenges with multithreading?

Yes, challenges include thread synchronization, potential deadlocks, and increased complexity in debugging and maintaining code.
