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
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.")
}
