What are The Important Selenium with Java Interview Questions?
by Selenium Labs creating software impactSelenium
is the first thing, which people consider when people plan to automate web
applications testing. This is a beneficial tool as it is not just open source
but it is also a portable software testing framework designed for web
applications, which support many languages like C#, Java, Python, Ruby, etc.
Here selecting the right language depends on the application under test, the
supporting community, usability, availability of the test automation
frameworks, elegance, and seamless building integration. Java is a famous programming
language and it is also the third most well-known back-end technology after SQL
and JavaScript.
Now
if you want to learn about the importance of Selenium with Java interview questions,
here comes a list of a few:
1. Why do developers

·
Java is more
popular to use in commercial applications compared to other programming
languages such as Python. Therefore, it makes integrating Selenium tests
easier.

4. What is Encapsulation in Java? How to achieve or implement it?
·
Encapsulation in Java is the procedure
of binding corresponding methods or data together into a single unit. There are
two ways to implement or achieve encapsulation in the Java program.

Offer the public setter and getter
methods in the class for modifying or setting the value of variables.
5. What is data
hiding in Java and how to achieve it?
Data hiding is the method that allows the users to directly prevent accessing variables or data members from outside the class so that they can achieve data security. It is possible to implement data hiding programmatically by declaring the data variables or members as private.
