QUESTION 7 OF 20

How is a volatile keyword used in Java?

This technical question assumes you know the definition of the term the Salesforce 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 Salesforce CRM is heavily dependent on the use of keywords, this concept is important to know."

Community answers are written by other candidates practicing this set. Reading how others frame the same question is one of the fastest ways to sharpen your own.

Anonymous Answer

Volatile is used to make a class thread-safe by reading the value directly from its space in memory. This can be used to ensure threads or variables are not cached in case they may change.
