Scala Stack equals() 方法与示例
在 Scala Stack class中， equals()方法用于检查两个堆栈是否由相同顺序的相同元素组成。
Method Definition: def equals(o: Any): Boolean
Return Type: It returns true if both the stacks are same or else returns false.
示例 #1：
// Scala program of equals()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stacks
val s1 = Stack(1, 3, 2, 7, 6, 5)
val s2 = Stack(1, 3, 2, 7, 6, 5)
// Print the stack
println("Stack_1: " + s1)
println("Stack_2: " + s2)
// Applying equals method
val result = s1.equals(s2)
// Display output
println("Stack_1 == Stack_2: " + result)
}
}
输出：
Stack_1: Stack(1, 3, 2, 7, 6, 5)
Stack_2: Stack(1, 3, 2, 7, 6, 5)
Stack_1 == Stack_2: true
示例 #2：
// Scala program of equals()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stacks
val s1 = Stack(1, 3, 2, 7, 6, 5)
val s2 = Stack(7, 3, 12, 7, 6, 5)
// Print the stack
println("Stack_1: " + s1)
println("Stack_2: " + s2)
// Applying equals method
val result = s1.equals(s2)
// Display output
println("Stack_1 == Stack_2: " + result)
}
}
输出：
Stack_1: Stack(1, 3, 2, 7, 6, 5)
Stack_2: Stack(7, 3, 12, 7, 6, 5)
Stack_1 == Stack_2: false
