带有示例的 Scala Map toArray() 方法

toArray()方法用于显示来自 Scala 映射的数组。

示例 #1:

// Scala program of toArray()
// 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 toArray method
        val result = m1.toArray
          
        for ( m5 <-result )
        {
           println(m5 )
        } 
  
    }
}
输出:
(3,geeks)
(4,for)

示例 #2:

// Scala program of toArray()
// 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 toArray method
        val result = m1.toArray
          
        for ( m5 <-result )
        {
            // Display output
            println(m5 )
        } 
          
    }
}
输出:
(3,geeks)
(4,for)
(2,cs)
