I'm trying to create a function to check if a string is a date. However, the following function got the error.
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
import java.sql._
import scala.util.{Success, Try}
def validateDate(date: String): Boolean = {
val df = new java.text.SimpleDateFormat("yyyyMMdd")
val test = Try[Date](df.parse(date))
test match {
case Success(_) => true
case _ => false
}
}
Error:
[error] C:\Users\user1\IdeaProjects\sqlServer\src\main\scala\main.scala:14: type mismatch; [error] found : java.util.Date [error] required: java.sql.Date [error] val test = Try[Date](df.parse(date)) [error] ^ [error] one error found [error] (compile:compileIncremental) Compilation failed [error] Total time: 2 s, completed May 17, 2017 1:19:33 PM
Is there a simpler way to validate if a string is a date without create a function?
The function is used to validate the command line argument.
if (args.length != 2 || validateDate(args(0))) { .... }
java.sql._
- sotest
has the typeTry[java.sql.date]
- try replacing that import withimport java.util.Date
