In Scala programming language, there is an option for the programmer to use libraries of java because of its interoperability with java.

There are a few methods to extract the date of a program,

1) Java 8 Year

The java.time.year library is used to get the value of the current year.

Syntax:

val data_int = Year.now.getvalue

Program:

import java.time.Year

object MyClass {
    def main(args: Array[String]) {
        val year: Int = Year.now.getValue; 
        printf(" "+year)
    }
}

Output

2) Java 8 localDate

The java.time.localDate library is used to get the current date and we can extract year also using its method.

Synatx:

val data_int = LocalDate.now.getvalue

Example:

import java.time.LocalDate

object MyClass {
    def main(args: Array[String]) {
        val year: Int = LocalDate.now.getYear; 
        printf(" "+year)
    }
}

Output

3) Java Calendar

The java.util.calendar is used to to get calendar information using the getInstance method. And passing the Calendar.YEAR to it will return the value of Year.

Synatx:

val year = Calendar.getInstance.get(Calendar.YEAR)

Example:

import java.util.Calendar

object MyClass {
    def main(args: Array[String]) {
        val year: Int = Calendar.getInstance.get(Calendar.YEAR); 
        printf(" "+year)
    }
}
