The toString() method is utilized to return a string representation of the queue object.
Method Definition: def toString(): String
Return Type: It returns a string representation of the queue object.
Example #1:
// Scala program of toString() // method // Import Queue import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a queue
val q 1 = Queue( 1 , 2 , 3 , 4 , 5 )
// Print the queue
println(q 1 )
// Applying toString method
val result = q 1 .toString
// Display output
print( "String representation of the queue object: " + result)
}
} |
Output:
Queue(1, 2, 3, 4, 5) String representation of the queue object: Queue(1, 2, 3, 4, 5)
Example #2:
// Scala program of toString() // method // Import Queue import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a queue
val q 1 = Queue( 5 , 2 , 13 , 7 , 1 , 3 )
// Print the queue
println(q 1 )
// Applying toString method
val result = q 1 .toString
// Display output
print( "String representation of the queue object: " + result)
}
} |
Output:
Queue(5, 2, 13, 7, 1, 3) String representation of the queue object: Queue(5, 2, 13, 7, 1, 3)
