Before starting your job search, look at these common Java interview questions asked during real interviews and understand the answers, but instead of memorizing the answers try to complete further research and come with your own personal solution for the interview question. The more prepared you are for what you will encounter, the more successful you will be. This collection of Java interview question could be also useful for software developers who need to interview Java developer.

Java Collections Interview Questions

Java Collections interview questions - there are an experienced developers who believe there is no need to memorize core elements of Java Collections Framework - interfaces, implementations and algorithms. These Java developers wrongly assume that if the programmer can google interview questions, there is not point to remember the answer and correct answers on these Java collections interview questions proves nothing. In some ways these developers are correct, the most important thing for Java developer, is that developer could think, not memorize. In my opinion, the interviewer have to ask question about Java Collections to know if the candidate could demonstrate a basic understanding of the most common data structures. For example, the hiring manager could use a few quick questions during phone screening interview. Once again, it would be enough to ask junior Java developer question like "What is HashMap and Map?", while Java Collections interview question for experienced developers may sounds like "When would you use a vector versus a linked list?".
