QUESTION 7 OF 20

How is a volatile keyword used in Java?

This technical question assumes you know the definition of the term the Amazon interviewer is asking about and only requests that you describe how it is used. By carefully listening to the interview's questions, you will provide the answer they are expecting. If you begin to think about your answer while the interviewer is still talking, you may miss the question's essence and give an answer which is not related to the question.

"A volatile keyword is used in Java with variable and threads which read its value directly from its memory location. This ensures the value is read exactly as it is contained in the memory location, and that the threads or variables do not cache it in case it changes. Since many Amazon applications are heavily dependent on the use of keywords, this concept is important to know."
