Scala Iterator addString() method with a start, a separator and an end with example
The addString method utilized to append the elements of the Scala Iterator to a String Builder.This method is same as addString() method but here a start, a separator and an end is also included.
Method Definition: def addString(b: mutable.StringBuilder, start: String, sep: String, end: String): mutable.StringBuilder
Where, sep is the separator stated.
Return Type: It returns the elements of the Iterator in the String Builder and a start, a separator and an end is also included here.
Example #1:
Scala
// Scala program of addString() method // with a start, a separator and an // end // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a Iterator val m 1 = Iterator( 1 , 3 , 4 , 8 ) // Applying addString method val result = m 1 .addString( new StringBuilder(), " = >", "|", ".") // Displays output println(result) } } |
Output:
=>1|3|4|8.
Example #2:
Scala
// Scala program of addString() method // with a start, a separator and an // end // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a Iterator val m 1 = Iterator( 1 , 3 , 3 , 8 ) // Applying addString method val result = m 1 .addString( new StringBuilder(), " = >", "|", ".") // Displays output println(result) } } |
Output:
=>1|3|3|8.
So, here the identical element is not removed like in maps.
