Scala Programming: Remove a specific element from an given array

Last update on June 12 2025 12:55:55 (UTC/GMT +8 hours)

Write a Scala program to remove a specific element from an given array.

Note: The size of an Array can't be changed, so we can't directly delete elements from an array but replace them with "" / null etc

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"${x}, ")        
       }
     println("\nReplace some elements with ''/null etc.:")
      colors(0) = ""
      colors(3) = null
   println("Now the Original Array becomes:")
   // Print all the array elements
      for ( x <- colors ) {
         print(s"${x}, ")        
       }
  }
}

Sample Output:

Original Array elements:
Red, Blue, Black, Green, White, 
Replace some elements with ''/null etc.:
Now the Original Array becomes:
, Blue, Black, null, White,

Go to:

PREV : 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.
NEXT : Write a Scala program to rotate one element left of an given array (length 1 or more) of integers.
