By asking such wide questions, you are putting yourself at shame in public and claim you are too lazy to even find basic answers.
To avoid this, programmers have a secret trick, they use a search engine. Google is your friend, Google only find 2,800,000 answers.

link on first page of Google
Non-blocking I/O (Java) - Wikipedia, the free encyclopedia[^]

I am not rude to you, YOU are rude to yourself !
Nobody knowing that you ask such questions will ever take you seriously. Your question claim that your main effort to find the answers is this question itself. If you want a teacher, hire one.
