In Scala, you can split a string using the split() method, which returns an array of substrings based on the delimiter specified.
Here's an example:
val str:String = "Splitting, a string, in Scala"
val delimiter:String = ","
// Splitting the string using the delimiter
val substrings:Array[String] = str.split(delimiter)
// Printing the substrings
substrings.foreach { substring =>
println(substring)
}
Output:
Splitting
a string
in Scala
In the example above, we first defined a string str and a delimiter ",". We then used the split() method to split the string into an array of substrings, based on the delimiter specified.
We used the foreach() method to print each substring, one by one.
Note that the split() method also takes an optional second argument, which specifies the maximum number of splits to be made. If not specified, the entire string is split. Here's an example:
val str:String = "Splitting a string in Scala"
val delimiter:String = " "
// Splitting the string using the delimiter and specifying a maximum of 2 splits
val substrings:Array[String] = str.split(delimiter, 2)
// Printing the substrings
substrings.foreach { substring =>
println(substring)
}
Output:
Splitting
a string in Scala
In this example, we specified a maximum of 2 splits using the second argument of the split() method. As a result, the string was split into only 2 substrings.
