How to get current timestamp in Scala as a string without spaces?
In this article, we will learn to get the current timestamp in Scala as a string without spaces. Getting the current timestamp involves retrieving the current date and time information and formatting it into a string representation without any spaces, typically using classes like java.time.LocalDateTime, java.util.Date, or java.time.Instant.
Get the Current Timestamp in Scala as a String without Spaces
Below are the possible approaches to get the current timestamp in Scala as a string without spaces.
Approach 1: Using java.time.LocalDateTime
- In this approach, we are using the java.time.LocalDateTime class from the Java time API to obtain the current date and time without time zone information.
- We then define a DateTimeFormatter object with a specific pattern (“yyyyMMddHHmmssSSS”) to format the date and time as a string without spaces.
- Finally, we use the format method of DateTimeFormatter to format the currentDateTime object into a timestamp string and print it to the console.
In the below example, java.time.LocalDateTime is used to get the current timestamp in Scala as a string without spaces.
import java.time.LocalDateTime
import java.time.format.DateTimeFormatter
object GFG {
def main(args: Array[String]): Unit = {
val currentDateTime = LocalDateTime.now()
val formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmssSSS")
val timestampString = currentDateTime.format(formatter)
println(timestampString)
}
}
Output:
Approach 2: Using java.util.Date
- In this approach, we are using the java.util.Date class to get the current date and time.
- We create a new SimpleDateFormat object with a specific pattern (“yyyyMMddHHmmssSSS“) to format the date and time as a string without spaces.
- Finally, we use the format method of SimpleDateFormat to format the currentDate object into a timestamp string and print it to the console.
In the below example, java.util.Date is used to get the current timestamp in Scala as a string without spaces.
import java.util.Date
import java.text.SimpleDateFormat
object GFG {
def main(args: Array[String]): Unit = {
val currentDate = new Date()
val formatter = new SimpleDateFormat("yyyyMMddHHmmssSSS")
val timestampString = formatter.format(currentDate)
println(timestampString)
}
}
Output:
Approach 3: Using java.time.Instant
- In this approach, we are using the java.time.Instant class from the Java time API to get the current instant, which represents a point in time without time zone information.
- We then convert the currentInstant object to a string using its toString method and remove spaces, colons, hyphens, and periods from the string to create a timestamp string without spaces.
- Finally, we print the timestamp string to the console.
In the below example, java.time.Instant is used to get the current timestamp in Scala as a string without spaces.
import java.time.Instant
object GFG {
def main(args: Array[String]): Unit = {
val currentInstant = Instant.now()
val timestampString = currentInstant.toString.replace(" ", "").replace(":", "").replace("-", "").replace(".", "")
println(timestampString)
}
}
