Program to get date in Scala

import java.util.Calendar
import java.text.SimpleDateFormat

object MyClass {
    def main(args: Array[String]) {
        val cal = Calendar.getInstance
        val dateTime = cal.getTime
        
        println("Full date information : " + dateTime)
        
        val dateFormat = new SimpleDateFormat("dd")
        val date = dateFormat.format(dateTime)
        println("Date is : " + date)
        
        val dateFormat2 = new SimpleDateFormat("MMM")
        val month = dateFormat2.format(dateTime)
        println("Month is : " + month)
        
        val dateFormat3 = new SimpleDateFormat("YYYY")
        val year = dateFormat3.format(dateTime)
        println("Year is : " + year)
    }
}

Output

Full date information : Fri Apr 24 16:59:22 GMT 2020
Date is : 24
Month is : Apr
Year is : 2020

Extracting month number

In Scala, we can extract the string in the form of the number instead of a string. The date format provides an option for this too.

The format "MM" does our work.

Program to extract month as a number

import java.util.Calendar
import java.text.SimpleDateFormat

object MyClass {
    def main(args: Array[String]) {
        val cal = Calendar.getInstance
        val dateTime = cal.getTime
        
        val dateFormat = new SimpleDateFormat("MM")
        val month = dateFormat.format(dateTime)
        
        println("Month number is : " + month)
    }
}

Output

Month number is : 04

Formatting month string

We can use string formatting methods like toUpperCase and toLowerCase to extract month as an uppercase string or lowercase string.

Program:

import java.util.Calendar
import java.text.SimpleDateFormat

object MyClass {
    def main(args: Array[String]) {
        val cal = Calendar.getInstance
        val dateTime = cal.getTime
        
        val dateFormat = new SimpleDateFormat("MMM")
        val month = dateFormat.format(dateTime).toUpperCase
        println("Month is : " + month)
        
        val Lmonth = dateFormat.format(dateTime).toLowerCase
        println("Month is : " + Lmonth)
    }
}

Output

Month is : APR
Month is : apr
