在 Scala Stack class
,則使用pushAll()方法將集合中的元素添加到堆棧中。
函數定義: def pushAll(elems: IterableOnce[A]): Stack.this.type
返回類型: It returns a stack that contains all the elements of the given collection.
範例1:
// Scala program of pushAll()
// method
import scala.collection.mutable.Stack
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a stack
var s1 = Stack[String]()
// Creating a set
var s2 = Set("C++", "Java", "Python", "Scala")
// Print the set
println(s2)
// Applying pushAll method
s1.pushAll(s2)
// Print the stack
println(s1)
}
}
輸出:
Set(C++, Java, Python, Scala) Stack(Scala, Python, Java, C++)
範例2:
// Scala program of pushAll()
// method
import scala.collection.mutable.Stack
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating a stack
var s1 = Stack[String]()
// Creating another stack
var s2 = Stack("C++", "Java", "Python", "Scala")
// Print the stack
println(s2)
// Applying pushAll method
s1.pushAll(s2)
// Print the stack
println(s1)
}
}
輸出:
Stack(C++, Java, Python, Scala) Stack(Scala, Python, Java, C++)
