Program to convert Java Set of floats to a String in Scala
  • Last Updated : 03 Jan, 2020

A java Set of floats can be converted to a String in Scala by utilizing toString method of Java in Scala. Here, you need to import Scala’s JavaConversions object in order to make this conversions work.
Now, lets see some examples and then discuss how it works in details.
Example:1#




// Scala program to convert Java set 
// to a String 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 floats in Java
        val set = new java.util.HashSet[Float]()
          
        // Adding floats to the set
        set.add(3.2f)
        set.add(6.4f)
        set.add(9.6f)
          
        // Converting set to a String
        val str = set.toString
          
        // Displays output
        println(str)
      
    }
}
Output:
[3.2, 6.4, 9.6]

Here, the digit after decimal is different for each element of the set and so, the resultant output is arranged in the ascending order of the digit after the decimal.
Example:2#




// Scala program to convert Java set 
// to a String 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 floats in Java
        val set = new java.util.HashSet[Float]()
          
        // Adding floats to the set
        set.add(2.1f)
        set.add(3.1f)
        set.add(1.1f)
          
        // Converting set to a String
        val str = set.toString
          
        // Displays output
        println(str)
      
    }
}
Output:
[2.1, 3.1, 1.1]

Here, the digit after the decimal is same for all the elements of the list so, the resultant output is in same order as stated above.
