What is the difference between JDK and JRE. ?

Suppose I created an application and compiled to MyApp.class. How would the person use that, using JDK or JRE?

This is a simple "what is ..." question. Such questions are answered the quickest and the best by doing a search instead of asking the question on a forum. This question has been asked many times before.

I literally copied your question into Google and it found approximately 28.300 answers for me in a fraction of a second.
