Scala Stack toString() method with example

In Scala Stack class, the toString() method is utilized to return a string representation of the stack object.

Method Definition: def toString(): String

Return Type: It returns a string representation of the stack object.

Example #1:

// Scala program of toString()
// method

// Import Stack
import scala.collection.mutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating stack
        val s1 = Stack(1, 2, 3, 4, 5)

        // Print the stack
        println(s1)

        // Applying toString method
        val result = s1.toString

        // Display output
        print("String representation of the stack object: " + result)

    }
}

Output:

Stack(1, 2, 3, 4, 5)
String representation of the stack object: Stack(1, 2, 3, 4, 5)

Example #2:

// Scala program of toString()
// method

// Import Stack
import scala.collection.mutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating stack
        val s1 = Stack(5, 2, 13, 7, 1, 3)

        // Print the stack
        println(s1)

        // Applying toString method
        val result = s1.toString

        // Display output
        print("String representation of the stack object: " + result)

    }
}

Output:

Stack(5, 2, 13, 7, 1, 3)
String representation of the stack object: Stack(5, 2, 13, 7, 1, 3)
