Scala Programming: Find the index of an element in a given Array
Scala Programming Array Exercise-5 with Solution
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)
