Let's face it; no one likes the interview process. Well, certainly not the people being interviewed anyway. You have to be on your best behavior, you only get one chance to get it right, and it's like taking your driving test all over again. Over the years I've been to countless interviews. To get my first job out of college I attended some 15-20 interviews a week. Whether it was in Britain or over here in the States, the questions never really seemed to change from job to job. Not only that, but the answers to them are usually the same, with your own personal interpretation of course. Here I present 23 questions you're likely to be asked, and how I have learned to answer them. Why 23? Because I had more than 20 and less than 25. Remember, being interviewed is a skill, and if you do the preparation you should ace it every time. (See also: 12 Unique Ways to Score a Job Interview)

History of Java programming language
Java was started as a project called "Oak" by James Gosling in June
1991. Gosling's goals were to implement a virtual machine and a language
that had a
familiar C-like notation but with greater uniformity and simplicity than
C/C++. The first public implementation was Java 1.0 in 1995. It made
the promise of
"Write Once, Run Anywhere", with free runtimes on popular platforms. It
was fairly secure and its security was configurable, allowing for
network and
file access to be limited. The major web browsers soon incorporated it
into their standard configurations in a secure "applet"
configuration. popular quickly. New versions for large and small
platforms (J2EE and J2ME) soon were designed with the advent of "Java
2". Sun has not announced
any plans for a "Java 3".
Java Interview Questions
1. What is the difference between private, protected, and public?
These keywords are for allowing privileges to components such as java methods and variables.
Public: accessible to all classes
Private: accessible only to the class to which they belong
Protected: accessible to the class to which they belong and any subclasses.
Access specifiers are keywords that determines the type of access to the member of a class. These are:
* Public
* Protected
* Private
* Defaults
2. What's the difference between an interface and an abstract class? Also discuss the similarities. (Very Important)
Abstract class is a class which contain one or more abstract methods, which has to be implemented by sub classes. Interface is a Java Object containing method declaration and doesn't contain implementation. The classes which have implementing the Interfaces must provide the method definition for all the methods
Abstract class is a Class prefix with a abstract keyword followed by Class definition. Interface is a Interface which starts with interface keyword.
Abstract class contains one or more abstract methods. where as Interface contains all abstract methods and final declarations
Abstract classes are useful in a situation that Some general methods should be implemented and specialization behavior should be implemented by child classes. Interfaces are useful in a situation that all properties should be implemented.

Personal interview questions and answers
What was your biggest mistake?
There’s nothing wrong in admitting a mistake. A
human being is bound to commit mistakes. This time it is advantageous to go
back as far as possible in the past and find an answer.
The advantage of doing this is that a youngster is
expected to commit more mistakes than a mature and seasoned person. This would
give an impression that since that time you have committed mistakes but not
that big.
Personal interview questions and answers
Tell me something about your self.
Go prepared for this question, as this is the most frequently asked question in the interview.
Answer it covering your work experience, educational
qualifications and a little information about your family background.
Try to focus on key areas of your work while talking
about your professional experience. This is an open ended question and can help
you in taking the interview in which ever direction you want it to go.
You should know where to put a full stop to provoke
the desired question from the interviewer.
Why does this role interest you? Or why have you applied for this job?
Keep the focus of the answer to this question on your skills, experience and personal qualities.
Link the job requirement to your skills rather than
talking about the challenges, career and progression.
Why do you think should we take you for this job?
