How to a get substring after splited a string in scala?
I have some Strings like
val value1 = """int | 10"""
val value2 = """double | 0.1"""
val value3 = """duration | 60s"""
This means that "int | 10" itself a String.
I want to get the values like 10 , 0.1 , 60s from these Strings. I am new to scala so please let me know how can I achieve this value.

Their are multiple ways to do this. I'm sharing one such approach.
val value1 = """int | 10"""
val value2 = """double | 0.1"""
val value3 = """duration | 60s"""
println(value1.split("\|")(1).trim)
println(value2.split("\|")(1).trim)
println(value3.split("\|")(1).trim)
Result
10
0.1
60s

Using a regular expression match is perhaps the most flexible, though not the most efficient:
def extract(valueString: String): Option[String] = {
val ValueMatch = """.*|s*([^s]+)s*""".r
valueString match {
case ValueMatch(v) => Some(v)
case _ => None
}
}
You could also update the regular expression to extract the type as well as the value, and then check that the value conforms to the correct type, and return a value of the correct type.
