Question

Threads and concurrency are important programming topics that allow our workstations, phones, etc. to handle multiple tasks simultaneously, both in terms of a single application doing several things at the same time as well asmultiple applications executing at the same time.

Choose a topic from theConcurrency Lesson in the Java Tutorials(Links to an external site.)and summarize it in this thread; also provide an example of when we might implement or otherwise encounter this concept as programmers. If you prefer, you're also free to reference instead any other thread-related Java information that you find on the web, in a book, etc.

Concurrency introduction -
concurrency is the composition of independently executing processes.
Multi-threading or concurrent processing means performing more than one task at a time.
Concurrent processing is achieved by running more than one Thread in parallel.
Concurrency has three levels:
● Multiprocessing: Multiple Processors/CPUs executing concurrently.
● Multitasking: processes running concurrently on a single CPU. The OS executes these
tasks by switching between them.
● Multithreading: Multiple parts of the same program running together.
Thread Creation -
1) User class can implement Runnable interface and provide an implementation of run()
method. Contents inside the run() method are executed by a separate thread.
