Introduction to Kotlin

Print Cheatsheet

The main() Function

The main() function is the starting off point of every Kotlin program and must be included in the code before execution.

fun main() { // Code goes here }

Print Statements

A print statement outputs values to the output terminal.

Using a println() statement will create a new line in the output terminal after printing values, while a print() statement will not.

println("Greetings, earthling!") print("Take me to ") print("your leader.") /* Prints: Greetings, earthling! Take me to your leader. */


Comments are used to document what is happening inside of a program and are ignored by the compiler.

A single-line comment is used to write a comment on one line, while a multiline comment is used to write longer comments that span over multiple lines.

// This is a single-line comment /* This comment uses multiple lines */

Order of Execution

Code is read, compiled, and executed in top-down order.

fun main() { println("I will be printed first.") println("I will be printed second.") println("I will be printed third.") }
