StringBuilders
Just like an array buffer is useful for building arrays, and a list
buffer is useful for building lists, a StringBuilder is useful for
building strings. String builders are so commonly used that they
are already imported into the default namespace. Create them with
a simple new StringBuilder, like this:
| scala> val buf = new StringBuilder |
| buf: StringBuilder = |
| scala> buf += 'a' |
| res38: buf.type = a |
| scala> buf ++= "bcdef" |
| res39: buf.type = abcdef |
| scala> buf.toString |
| res41: String = abcdef
|
