Scala Programming: Find the index of an element in a given Array

Last update on June 12 2025 12:56:45 (UTC/GMT +8 hours)

Write a Scala program to find the index of an element in a given Array.

Sample Solution:

Scala Code:

object Scala_Array
{
  def main(args: Array[String]): Unit = 
 {
   val colors = Array("Red","Blue","Black","Green","White")
   println("Original Array elements:")
   // Print all the array elements
      for ( x <- colors ) {
         print(s"${x}, ")        
       }
   println("\n")
   println("Index of 'Red':", colors.indexOf("Red"))
   println("Index of 'Blue':", colors.indexOf("Blue"))
   println("Index of 'Black':", colors.indexOf("Black"))
   println("Index of 'Green':", colors.indexOf("Green"))
   println("Index of 'White':", colors.indexOf("White"))   
  }
}

Sample Output:

Original Array elements:
Red, Blue, Black, Green, White, 
(Index of 'Red':,0)
(Index of 'Blue':,1)
(Index of 'Black':,2)
(Index of 'Green':,3)
(Index of 'White':,4)

Go to:

PREV : Write a Scala program to check if the value of the fast or last element of a given array ( length 1 or more) are same or not.
NEXT : Write a Scala program to check whether the value of the fast or last element of two given array ( length 1 or more) of integers are same or not.
