3. KOTLIN INTRODUCTION
• Kotlin is a modern programming
language used for developing Android
apps. It was developed by JetBrains, and
its popularity increased when Google
started to support it.
• It is a general-purpose, statically typed,
open-source, cross-platform
programming language that can be used
with Java virtual machines.
• A modern and trending programming
language i.e. it combines object-oriented
and functional programming to create a
dominant language that is rich with up-to-
date features. Intuitive syntax, all-purpose
usability, and cyber security are a few of
these qualities.
4. FEATURES OF KOTLIN
PROGRAMMING
EASY TO LEARN
• Kotlin is easy to learn because it has a simple and
common syntax and programming structure, which
makes it an excellent choice for identifying and
modifying errors.
JAVA COMPATIBILITY
• Kotlin supports full Java interoperability. You can
easily call Kotlin code from Java and Java code from
Kotlin. Kotlin plays well with the Java programming
language. Moreover, a number of Java libraries can
be used in Kotlin projects, making it even more
compatible. This will allow the developer to switch
the programming language instead of changing the
codes.
5. FEATURES OF KOTLIN
PROGRAMMING
• This is one of the most powerful features of Kotlin
because the language is relatively safe and easy to
use. Furthermore, using the Null Safe function, it is
possible to avoid errors such as "NullPointException".
SMART CAST FUNCTION
• Because it has a sophisticated compiler, it is possible
to verify automatic casts, which increases the
effectiveness of the check timings.
SAFE AND RELIABLE
• The smart cast function's primary task is to determine
the type of function. This will carry out all operations
that are coded for a particular type and increase the
code's effectiveness.

7. BRANDS THAT
SWITCHED TO KOTLIN
PINTEREST
Pinterest, one of the
popular social media
platforms founded in
2010, migrated from Java
to Kotlin in 2016. And the
prime reason behind is
the kind of robustness
that Kotlin offers.
UBER
The foremost brand that
embraced Kotlin for its
influence in Android mobile
app market is Uber. To enjoy
better internal tool and
model management, along
with error-free and faster
performance, Uber switched
to Kotlin
COURSERA
The popular MOOC
depends partially on this
Android application
development language
for delivering highly
dynamic features and
seamless experience to
their audience.
TRELLO
Trello has started writing
all the codes now in this
programming language. And
the reason behind is that
Kotlin offers far concise
APIs, exceptional
versatility, and
interoperability with Java.
8. IS KOTLIN
STILL
RELEVANT IN
2022?
Yes, Kotlin is still relevant in 2022. As the market
for Android apps expands, there is an increasing
need for mobile developers, which results in the
increasing demand for the Kotlin language for
android. It is a beginner-friendly programming
language with a small codebase, making it a
reliable and consistent language for code
development. This programming language is now
preferred by many companies such as Pinterest,
Netflix, etc.
9. WHY CHOOSE
KOTLIN OVER
JAVA?
• Readability
Kotlin has more readable and accurate code than Java, which
makes the application easier to grasp.
• Null-Safe
By default, Kotlin is null-safe. It prohibits assigning a null value to variables. However, we are able to
assign null values to variables in Java, which may result in a null pointer exception that could cause
the application to crash.
• Extension Functions
In Java, you have to create a class, while in Kotlin it is already there.
• Static Members
Static Members are present in Java while Kotlin does not contain a static member for a class.
10. WHY CHOOSE
KOTLIN OVER
JAVA?
• Smart Casts
Smart Casts are not present in Java while it is present in Kotlin.
• System Type
There are different kinds of references related to the basic concept of class in Java and in Kotlin it
offers nullability support, universal guards, and type inference.
• Constructors
In Java, constructors can be utilized to take parameters while Kotlin Kotlin includes a primary
constructor and a secondary constructor.
• No Checked Exceptions
It is a bit problematic in Java while Kotlin removes exceptions entirely.
