Scala Tuple Example: Function Return Multiple Values

You can return multiple values by using tuple. Function does not return multiple values but you can do this with the help of tuple. In the following example, we are describing this process.

object MainObject{
    def main(args:Array[String]){
        var tupleValues = tupleFunction()
        println("Iterating values: ")
        tupleValues.productIterator.foreach(println)    // Iterating tuple values using productIterator
    }
    def tupleFunction()={
        var tuple = (1,2.5,"India")
        tuple
    }
}

Output:

Iterating values: 
1
2.5
India
