Core Java Interview Questions and Answers with Examples

Closed

I need 250 interview questions for Java core technology. Questions should be practical one and needs to be given along with appropriate answers. If example code is needed to explain the concept then that code needs to be given along with the answers.

Strict Note: There are already plenty of question and answers available on the net, but we do not want to replicate same set of questions and if content of questions matches with any existing website then work will not be accepted or revised, and consequently project will be rejected. So if you have real working experience with core java and you can produce these questions and answers based on your experience then I welcome you, otherwise I request not to bid for the project.

Your question flow should be like an interviewer starts with basics and type of questions he/she asked.

Here is sample questions and answers:

Q: What is Java?

A: Java is a high-level programming language originally developed by Sun Microsystems and released in 1995.

Q: What are then supported platforms for Java?

A: Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX, like Redhat Linux, CentOS, Ubuntu etc.

Skills: J2EE, Java, Software Architecture
