Scala - Check Vectors Contains an Element or Not?

Here, we will create an object of Vector collection. Then we will check a vector that contains an item using contains() method and then print the appropriate message on the console screen.

The Vector is an immutable data structure. We can access vector elements randomly. It extends an abstract class AbstractSeq and IndexedSeq trait. We use the Vector collection to store a large number of elements.

Scala code to check a vector contains an item or not

The source code to check a vector contains an item or not is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to check a vector contains 
// an item or not

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var vector = Vector(50, 20, 40, 30, 70);

    if (vector.contains(30))
      println("vactor contains item 30");
    else
      println("vactor does not contain item 30");
  }
}

Output

vactor contains item 30

Explanation

Here, we used an object-oriented approach to create the program. And, we imported Collection classes using the below statement,

import scala.collection.immutable._

And, we also created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.

In the main() function, we created a vector vector using Vector collection. Then we check created vector contains item 30 using contains() method and print the appropriate message on the console screen.
