Kotlin Booleans

In programming, sometimes you just need a yes-or-no answer. That’s where Booleans come in handy.

Think of them as tiny flags that only flip between two states:

A Boolean is a data type that only accepts two outcomes: true or false.

val isSunny: Boolean = true 
val isNight: Boolean = false  

println(isSunny)  // true 
println(isNight)  // false

If you skip the Boolean label, Kotlin still knows what you mean:

val likesMusic = true 
val hatesNoise = false 

println(likesMusic)  // true 
Println(hatesNoise)  // false

No type declaration needed — Kotlin is clever that way!

You can use comparisons to generate Boolean values:

val a = 20 
val b = 15 

Println(a > b) // true, because 20 is more than 15

Or even shorter:

println(5 < 2) // false, because 5 is not less than 2

Want to see if values match? Use the double equal sign ==:

val score = 100  

println(score == 100) // true 
Println(score == 90)  // false

Boolean results are the foundation of decision-making in code.

They power up:
