how can i create custom exceptions in Scala extending Exception
class and throw them when exception occurs as well as catch them.
example in java :
class CustomException extends Exception {
public final static String _FAIL_TO_INSERT = "FAIL_TO_INSERT";
}
final case class CustomException(private val message: String = "",
private val cause: Throwable = None.orNull)
extends Exception(message, cause)
Just try catch:
try {
throw CustomException("optional")
} catch {
case c: CustomException =>
c.printStackTrace
}
