Scala Stack toString()方法及示例
在Scala Stack类中, toString() 方法被用来返回堆栈对象的字符串表示。
方法定义: def toString():String
返回类型。它返回堆栈对象的字符串表示。
例子 #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)
}
}
输出。
Stack(1, 2, 3, 4, 5)
String representation of the stack object: Stack(1, 2, 3, 4, 5)
例子#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)
}
}
输出。
Stack(5, 2, 13, 7, 1, 3)
String representation of the stack object: Stack(5, 2, 13, 7, 1, 3)
