Create an empty string:
scala> val emptyString: String = ""
emptyString: String = ""
Concatenate strings:
scala> "London " + "city"
res1: String = London city
String length:
scala> val str: String = "London " + "city"
str: String = London city
scala> str.length()
res7: Int = 11
scala> str.size
res8: Int = 11
Mulitine String:
scala> val str: String = """I am a multiline
| String
| In Scala""".stripMargin
str: String =
I am a multiline
String
In Scala
Parametrize a String:
scala> val name: String = "London"
name: String = London
scala> val str: String = s"""${name} city""".stripMargin
str: String = London city
Concatenate a Sequence of Strings:
scala> val xs: List[String] = List("To", "be", "or", "not", "to", "be")
xs: List[String] = List(To, be, or, not, to, be)
scala> xs.mkString(" ")
res1: String = To be or not to be
