Kotlin Compiler - Comes bundled with standard Kotlin package

Compile the application using the Kotlin compiler.

$ kotlinc hello.kt -include-runtime -d hello.jar

The -d option indicates what we want the output of the compiler to be called and may be either a directory name for class files or a .jar file name. The -include-runtime option makes the resulting .jar file self-contained and runnable by including the Kotlin runtime library in it. If you want to see all available options run

$ kotlinc -help

Run the application.

$ java -jar hello.jar
