How to find largest of two numbers in Kotlin?

In this tutorial, you shall learn how to find the largest of given two numbers in Kotlin, with the help of example programs.

Kotlin – Find largest of two numbers

To find the largest of given two numbers in Kotlin, we can use Greater-than or Less-than operator and compare the two numbers.

If a and b are given two numbers, the condition to check if a is greater than b is

a > b

The above condition returns true if a is greater than b, or else, it returns false.

Program

In the following program, we read two numbers from user and store them in a and b, then use Greater-than comparison operator to find the largest of a and b.

Main.kt

fun main() {
    print("Enter first number : ")
    val a = readLine()!!.toDouble()
    print("Enter second number : ")
    val b = readLine()!!.toDouble()

    if (a > b) {
        print("$a is the largest of $a and $b")
    } else {
        print("$b is the largest of $a and $b")
    }
}

Output #1

Enter first number : 4
Enter second number : 6
6.0 is the largest of 4.0 and 6.0

Output #2

Enter first number : -9
Enter second number : 7
7.0 is the largest of -9.0 and 7.0
