Scala 将Java数组转换为Scala流的程序

通过利用Scala中Java的toStream方法，可以将Java的双精度Set转换为Scala中的流。在这里，我们需要导入Scala的JavaConversions对象以使此转换工作正常。

现在，让我们看一些示例，然后讨论它是如何工作的。

例子：1#

// Scala program to convert Java set 
// to Stream in Scala
  
// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating set of doubles in Java
        val set = new java.util.HashSet[Double]()
          
        // Adding doubles to the set
        set.add(4.53)
        set.add(122.53)
        set.add(90.53)
          
        // Converting set to Stream 
        val stream= set.toStream
          
        // Displays Stream 
        println(stream)
      
    }
}

Stream(90.53, ?)

例子：2#

// Scala program to convert Java set 
// to Stream in Scala
  
// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating set of doubles in Java
        val set = new java.util.HashSet[Double]()
          
        // Adding doubles to the set
        set.add(12.08)
        set.add(12.456)
        set.add(12.11)
          
        // Converting set to Stream 
        val stream= set.toStream
          
        // Displays Stream 
        println(stream)
      
    }
}
