// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a Stream
        val m1 = Stream(1, 2, 3, 4, 5, 7)
          
        // Applying takeRight method
        val result = m1.takeRight(2)
          
        // Displays output
        println(result)
      
    }
}

输出：

Stream(5, 7)

示例 #2：

// Scala program of takeRight()
