带有示例的 Scala Map toSeq() 方法

toSeq()方法用于显示来自 Scala 映射的序列。

Method Definition: def toSeq: Seq[A]

Return Type: It returns a sequence from the stated map.

示例 #1：

// Scala program of toSeq()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a map
        val m1 = Map(3 -> "geeks", 4 -> "for", 4 -> "for")
          
        // Applying toSeq method
        val result = m1.toSeq
          
        // Displays output
        println(result)
      
    }
}

输出：

ArrayBuffer((3, geeks), (4, for))

示例 #2：

// Scala program of toSeq()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a map
        val m1 = Map(3 -> "geeks", 4 -> "for", 2 -> "cs")
          
        // Applying toSeq method
        val result = m1.toSeq
          
        // Displays output
        println(result)
      
    }
}

输出：

ArrayBuffer((3, geeks), (4, for), (2, cs))
