Java Preparation Tips 2017

Java Preparation Tips 2017:
To prepare a Java fresher interview, it is always better to know what particular skills companies are looking for.
This article explains everything in detail and make it very clear to help you be more aware of an interview and yourself.

Tip #1: Your front door, good looking Resume
Your resume is more important to get interview calls from top organizations. In order to make your profile unique from others; you must complete Oracle Java Certifications and make your resume headline something like below:
Oracle Java SE 8 Certified Programmer
Oracle Java EE 6 EJB Certified Expert

Given two identical programmers in an interviewer, would he hire the one who is certified or the one who is not? Perhaps the certification gives one a slight edge.

Looking back at these points, we conclude that certifications are most important for beginners. Studying for the tests give you something concrete to focus on, and being Java certified gives you one extra bullet point on a resume.

Tip #2: Important Java Topics one must know for an Interview

The basic important Java questions are from OO concepts and core Java APIs.
JDK
JRE
JVM
Write once and run anywhere – Platform Independence
Runtime Environment
API(Application Programming Interface)
The Java main method.
Classloader
Java keywords
Instance, Class and Local variables
Reference types (primives and objects)
Constructor vs. Methods
Keyword final
The static keyword (static method, static variables..)
Difference between static vs. instance
Difference between this vs. super
Inheritance
Abstraction
Polymorphism
Sub class, Super Class
Composition
Encapsulation
Method overloading
Method overriding
Java Packages
Java APIs
Java Exceptions
Runtime Exceptions
Compile time exceptions
Try/catch block
finally
String vs. StringBuffer
StringBuffer vs. StringBuilder
Primitives (int, double, float, long, byte..)

Tip #3: Practice Good Nonverbal Communication and be honest and don’t bluff

Good communication skills include listening and letting the person know you heard what he said. Observe your interviewer, and let your mind think about the answer before you speak.

It’s about demonstrating confidence: standing straight, making eye contact and connecting with a good, firm handshake. That first impression can be a great beginning — or quick ending — to your interview.

Answer what you know, confidently. If you have been asked a question that you don’t know for example something like advanced Java concepts like JAX-RS, JAX-WS, Start by telling “I am not aware of that”. Never tell a wrong answer confidently. That will make them doubt your correct answers also or may feel that they were guesses.

Tip #4: Write programs on paper instead of talking

Telling the interviewer more than he needs to know could be a fatal mistake. When you have not prepared ahead of time, you may tend to ramble, sometimes talking yourself right out of the job. It is good to write a code or diagram in a paper will definitely impress your interviewer.

Tip #5: Good Attitude

Attitude plays a key role in your interview success. Overconfidence is as bad, if not worse, as being too reserved. When asked if they have any questions, most candidates answer, “No.” Wrong answer. It is extremely important to ask questions to demonstrate an interest about the company like products or projects. Asking questions also gives you the opportunity to find out if this is the right place for you. The best questions come from listening to what is asked during the interview and asking for additional information.
