Kotlin Ternary Operator with Example

The ternary operator is the only operator that takes 3 operands. It is used to implement conditional statements in a single line. Various programming languages such as Java, JavaScript, C#, etc have ternary operator feature. Its syntax looks like this:

(condition) ? (expression1) : (expression2)

If the condition is true, expression1 is executed otherwise expression2.

Does Kotlin Support Ternary Operator?

Kotlin does not support ternary operator directly. But we can implement it in Kotlin using a one-liner if else. It’s also known as shorthand syntax for writing simple if-else expressions.

Here is an example that demonstrates the implementation of the ternary operator in Kotlin using if else.

fun main() {
    val x = 10
    val result = if (x > 5) "greater than 5" else "less than or equal to 5"
    println(result)
}

Output:

greater than 5
