the Latin root of the word concurrency means running together. In programming, you can have multiple threads running in parallel in a program executing different tasks at the same time. Therefore it is a powerful and useful feature.

Parallel activities can be implemented as threads: running multiple threads in parallel at the same time is called multi-threading or concurrency.

A java thread can be created in two ways: by extending the thread class or by implementing the Runnable interface. Both of them have a method named run(). JVM will call this method when a thread starts executing.
