Scala Map addString() method with a separator with example
This method is identical to the addString() method but here a separator is also included.
Method Definition: def addString(b: StringBuilder, sep: String): StringBuilder
Where, sep is the separator stated.
Return Type: It returns the elements of the map in the String Builder and a separator is also added between the elements of the map.
Example #1:
// Scala program of addString() // method with a separator // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a map val m 1 = Map( "Beginner" - > 5 , "for" - > 3 , "cs" - > 2 ) // Applying addString method // and a separator val result = m 1 .addString( new StringBuilder(), "_" ) // Displays output println(result) } } |
Output:
Beginner -> 5_for -> 3_cs -> 2
Example #2:
// Scala program of addString() // method with a separator // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a map val m 1 = Map( "Beginner" - > 5 , "for" - > 3 , "Beginner" - > 2 ) // Applying addString method // and a separator val result = m 1 .addString( new StringBuilder(), "_" ) // Displays output println(result) } } |
Output:
Beginner -> 2_for -> 3
So, here the identical keys are removed.
