Java Interview Questions for 2 to 5 yrs - Java Developer

Hello All,
This blog lists the interview questions that you are likely to face in an Interview if you are Java developer between 2 to 5 years.
When you reach experience level of more than 2 years it is assumed by the interviewer that you have good hand on experience in Java stack.
Sometimes the interviews are for a specific project. Like a project may require candidate to have experience in Spring or Struts or Hibernate. Or sometimes the interview is not for a specific project and is for a open requirement.

Sometimes specific skills are looked for, like the candidate should have experience in SOAP and REST Web-services.

The interviewer is not expecting the candidate to know the designing or high level architecture of the project. What he is expecting is the candidate should be aware of the Project, the technologies used and should be aware of the role he played in the project. As this is not a fresher interview the questions would start with basics and then go in deep.

Below here are the list of questions.
