scala get set of chars from string
To get a set of characters from a string in Scala, you can convert the string to a sequence of characters and then convert it to a set. Here's an example:
val str = "Hello, World!"
val charSet = str.toSeq.toSet
In this example, the toSeq
method converts the string str
into a sequence of characters, and the toSet
method then converts the sequence into a set of characters. The resulting charSet
will contain all unique characters from the original string.
You can also use the distinct
method directly on the string to get a set of distinct characters:
val str = "Hello, World!"
val charSet = str.distinct.toSet
In this case, the distinct
method returns a new string that contains only the distinct characters from the original string, and then the toSet
method converts it into a set.
Either approach will give you a set of characters from the string.
