带有示例的 Scala Stack mkString() 方法
在 Scala Stack class
中, mkString()方法用于在字符串中显示堆栈的所有元素。
Method Definition: def mkString: String
Return Type: It returns a string containing all the element of the stack.
示例 #1:
// Scala program of mkString()
// 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)
// Print the stack
println(s1)
// Applying mkString method
val result = s1.mkString
// Display output
print("Stack: " + result)
}
}
输出:
Stack(1, 2, 3, 4)
Stack: 1234
示例 #2:
// Scala program of mkString()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack("Geeks", "for", "Geeks")
// Print the stack
println(s1)
// Applying mkString method
val result = s1.mkString
// Display output
print("Stack: " + result)
}
}
输出:
Stack(Geeks, for, Geeks)
Stack: GeeksforGeeks
