How to get the largest numbers by a ternary operation in Scala

Overview

In Scala, there is no default ternary operator or operation because it's redundant to have such operations. In Scala, we use if-else and else-if conditional statements. We use this conditional statement for purposes such as finding the largest of three numbers. Let's look at how we can do that below.

Syntax

Parameters

no1: This is the first number.

no2: This is the second number.

no3: This is the third number.

no1IsGreatest: This is to check if the first number no1 is the greatest of the three.

no2IsGreatest: this is to check if the second number no2 is the greatest of the three.

Return value

The value returned is no1 , no2, or no3. This is because when the no1IsGreatest condition returns true, no1 is the greatest. If the condition no2IsGreatest returns true , no2 is the greatest. If none of these conditions returns true, no3 is the greatest.

Example

object Main extends App {
        // create some numbers
        var num1 = 100
        var num2 = 2
        var num3 = 200
        var num4 = 9000
        var num5 = 100000
        // check greaters between 3 numbers
        checkGreatest(num1, num2, num3)
        checkGreatest(num4, num2, num3)
        checkGreatest(num5, num4, num3)
        def checkGreatest(a:Int, b:Int, c:Int) ={
          var large = 0
          // perform ternary operation
          large = if (a > b && a > c) a else if(b > a && b > c) b else c
          // print largest number
          printf("Largest between %d, %d and %d is: %d\n", a , b, c, large)
        }
        
}
