3. What are some advantages of using Enum over Enum int pattern and Enum string pattern?
Why the Interviewer Asks This Question
Since only experienced Java programmers will understand this question, the interviewer uses it to confirm your experience level, as noted in your resume. Interviewers ask these questions because it is common for candidates to exaggerate their resumes. It is highly likely that the interviewer has already researched your background in great detail using sources such as LinkedIn and other social media sites. This is why it is very difficult to exaggerate or enhance your qualifications.

How to Answer
If you have the experience necessary to respond to this question accurately, proceed. If not, communicate this to the interviewer. Your answer should always demonstrate your actual qualifications for this job. Interviewers understand that you may not have all the qualifications and are often willing to hire you with the expectation that they will provide additional training to bring you up to the level needed to perform this work. It is very typical for companies to hire junior-level programmers who they can train to use specific methodologies, processes, and procedures preferred by the company.

Answer Example
"Since I have coded using JDK 1.3 and 1.4, I am familiar with Enum string pattern and int pattern, which used public static final constants to represent a collection of well-known constants of things like 'MonthOfYear.' There were several problems with this approach, such as not having a dedicated Enum type string variable, which represented months of the year. This allowed it to take any arbitrary value. The Enum int pattern can take any arbitrary value, and the compiler won't prevent this. When using Enum, you get both type-safety and compiler checking."
