OVERVIEW
Kotlin is a general purpose, free, open source, statically typed “pragmatic” programming language initially designed for the JVM (Java Virtual Machine) and Android, and combines object-oriented and functional programming features. It is focused on interoperability, safety, clarity, and tooling support.
It has become very popular since it is compatible with Java (one of the most popular programming languages out there), which means that Java code (and libraries) can be used in Kotlin programs.
Kotlin is used for:
Mobile applications (specially Android apps)
Web development
Server side applications
Data science
And much, much more!

chmod 400 [Path of key pair file]Once launched in the Amazon EC2 Service, please connect to the instance via an SSH client using the ec2-user with the key pair associated at launch. Once connected as the ec2-user user, you will be able to sudo to the root user
Step 2. Verify the installation
Follow the steps to verify the Rust installation
1. Login with ssh
2. Type the below command to check the version
kotlinc -versionYou will see the responses as shown below.
How to use kotlin language in the terminal:

kotlinc helloworld.kt -include-runtime -d helloworld.jar4. After that run the below command:
java -jar helloworld.jar5. If you get the Hello, world! in output then your kotlin is working properly.
To monitor and assess application functions:-
a. Navigate to your Amazon EC2 console and verify that you're in the correct region.
b. Choose Instances and select your launched instance.
c. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.
