Java Interview Preparation Checklist For Developers
After you land an interview, you experience a wave of excitement that gets
replaced by nerves almost immediately. Although you have the skills necessary
required for the job, you must showcase those skills to your recruiting manager
during the interview to land the position. It is arguably the most critical part of
the job search phase that can make or break your confidence.
But the great thing is you can prepare yourself for the interview with the right
tools. Taking time to learn more about the company or what skills the job role
demands, networking with your peers, or practicing mock interview questions
can improve your chances of landing the job. In these slides, we have made a
Java interview checklist that helps you prepare for your upcoming interview
post-Java bootcamp.

3. Java Interview Questions
01 Why did you choose Java?
A
Java is a popular platform-independent language.
Once you compile a code on Java, it can run on any
device if Java Runtime Environment (JRE) is installed
in them. Therefore, most businesses develop their
enterprise applications on the Java environment and
need Java developers to help them deploy and
develop the applications for the clients. According to
the TIOBE index, Java is the third most popular
programming language globally. And it has a simpler
learning curve with a highly readable script.

4. 02 Difference between .equals() method and
equality operator(==) in Java?
A The .equals() method is defined in the Object class, while equality (==)
is binary operator. The equality operator(==) compares the reference
or memory location of objects in bulk. On the contrary, the .equals()
method verifies the comparison of values in the objects while the
equality operator verifies reference comparisons. Plus, you cannot
override the equality operator. But it is possible to overwrite the
.equals() method under special circumstances.

5. 03 What are Local variables and Instance
variables in Java?
A
There are three types of variables in Java - Local Variables, Instance
Variables, and Static Variables. A variable declared within the body of
the method is called a local variable. The Instance variable is declared
inside the class but outside the method. It is available within the
method, and other methods in the class are unaware of its existence.

What is ClassLoader?
A ClassLoader, a subsystem of Java Virtual Machine, is an abstract class
responsible for loading class files while running a Java program.
Security managers use these ClassLoaders to indicate security domains
with a program.
There are three built-in ClassLoaders in Java - Bootstrap ClassLoader,
Extension ClassLoader, and System/Application ClassLoader.

7.  Bootstrap ClassLoader
It is the first ClassLoader, a superclass of Extension classloader, that loads rt.jar file
containing the class files of Java Standard Edition such as java.net package classes
and java.io package classes.
 Extension ClassLoader
It is the child ClassLoader of Bootstrap and parent ClassLoader of System
ClassLoader. The extension ClassLoader runs the jar files located inside
$JAVA_HOME/jre/lib/ext directory.
 System/Application ClassLoader:
It is the third layer of classloader hierarchy and a child ClassLoader of Extension. It
loads the class files from the classpath set to the current directory. One can use
the "-cp" or "-classpath" switch to change the classpath.

A According to experienced coding bootcamp instructors, to reverse a
string in Java, one must first convert it to a StringBuilder (a mutable
string) which comes with an inbuilt function called reverse(). This
function reverses the string and returns the desired output. Lastly,
convert the reversed StringBuilder to String using the inbuilt function
toString(). One can also use the XOR operation or traditional for loop to
complete the job.

9. Apart from the technical skills, the bootcamp manager for Java
Training in Seattle points out that a candidate must work on
their personality. Every hiring manager runs a Java-related
interview to assess a candidate's skills.
For an entry-level position, the recruiter might ask questions
regarding the fundamental aspects of programming and how
well you know the concepts. But apart from that, the manager
would shoot some questions throughout the interview to
evaluate the candidate's personality and how well they fit into
the team.
How To Prepare For Java-Based Interview?

10. Here are tips for leaving a lasting
impression during the interview:
 Take time to research the company
Before entering the interview, learn more about
the company and its products and services,
customer demographics, and ownerships. You
can get the information on the company website
or check for the latest press releases and social
media handles to evaluate the company's tone,
voice, and key initiatives.

11.  Practice
Taking time to practice possible interview questions can come in
handy during the interview. Practicing before the mirror helps you
note your facial expressions and make you confident about your
responses.
 Ask questions
The interview is a two-way process where both parties ask questions and
assess the person sitting on the other side of the table. Soft-skill instructor
at Java bootcamp encourages the candidates to ask thoughtful questions
during the interview for two reasons. Firstly, it shows the candidate has
done due research in the company and is genuinely interested in working
with them. Secondly, it helps clear doubts in case you have any.

13. Conclusion
Java is an in-demand skill among recruiters, and
they are willing to pay lucrative compensation to
the right candidate. If you, too, want to join the
tech domains and earn coveted six-figure
annually, you need to join the Java Training in
Seattle organized by SynergisticIT. The program
teaches the fundamental and advanced-level
Java programming skills necessary for an entry-
level developer. Besides, technical training, the
bootcamp organizes soft skill training for the
candidates that can help them in nailing the job
during the interview.
