Java multithreading allows concurrent execution of two or more threads, enabling tasks to run simultaneously and improving application performance.

Threads in Java can be created by either extending the Thread class or implementing the Runnable interface, with Runnable preferred for better design and flexibility.

A thread in Java has several states: New, Runnable, Running, Blocked/Waiting, and Terminated, each representing a different stage of its execution.

To prevent thread interference and ensure data consistency, Java provides synchronization mechanisms such as synchronized methods and blocks, which control access to shared resources.

Java's ExecutorService and Executors utility class provide efficient thread management through thread pools. These pools help reuse threads for executing multiple tasks, reducing the overhead of thread creation.
