How to use Simple Parsing In Java

In this approach, we are using simple parsing techniques in Scala to convert a string representing a date (“2024-03-27”) into a GregorianCalendar object.
The simpleParse method splits the input string by hyphens and attempts to create a calendar object based on the parsed components (year, month, day).
If successful, it returns an Option[GregorianCalendar] representing the parsed date; otherwise, it returns None.

In the below example, the Simple Parsing is used to convert String to date time.

Scala

import java.util.{Calendar, GregorianCalendar}

class GFG {
  def simpleParse(dateString: String): Option[GregorianCalendar] = {
    dateString.split("-").toList match {
      case yyyy :: mm :: dd :: Nil =>
        try {
          Some(new GregorianCalendar(yyyy.toInt, mm.toInt - 1, dd.toInt))
        } catch {
          case _: NumberFormatException => None
        }
      case _ => None
    }
  }
}

object GFG extends App {
  val parser = new GFG

  // Input string representing date
  val dInput = "2024-03-27"

  // Parse the input string using simple parsing
  val maybeDate = parser.simpleParse(dInput)

  // Print the parsed DateTime object
  maybeDate match {
    case Some(date) =>
      println("Parsed DateTime: " + date.getTime)
    case None =>
      println("Invalid date format")
  }
}
