Example #1:
// Scala program of addString() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating an Iterator
val iter = Iterator( 7 , 6 , 8 , 1 )
// Applying addString method
val result = iter.addString( new StringBuilder())
// Displays output
println(result)
}
} |
Output:
7681
Example #2:
// Scala program of addString() // method // Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating an Iterator
val iter = Iterator( 7.7 , 6.1 , 8.6 , 1.1 )
// Applying addString method
val result = iter.addString( new StringBuilder())
// Displays output
println(result)
}
} |
Output:
7.76.18.61.1
