Here, we are going to learn how to compare two dates using compareTo() method in Scala programming language?

Scala - compareTo() Method Example

Here, we will create objects of the Date class and compare dates using the compareTo() method.

The compareTo() method returns:

• 0 if both are equal.
• >0 if the current date object comes after the specified date object.
• < 0 if the current date object comes before the specified date object.

Scala code to compare two dates using compareTo() method

The source code to demonstrate the compareTo() method of the Date class is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to compare two dates
// using compareTo() method

import java.util.Date;

object Sample {
  def main(args: Array[String]) {
    var date1 = new Date(2021, 5, 10);
    var date2 = new Date(2021, 5, 11);
    var date3 = new Date(2021, 5, 10);

    var result: Int = 0;

    result = date1.compareTo(date2);
    if (result == 0)
      println("date1 and date2 are equal");
    else
      println("date1 and date2 are not equal");

    result = date1.compareTo(date3);
    if (result == 0)
      println("date1 and date3 are equal");
    else
      println("date1 and date3 are not equal");
  }
}

Output

date1 and date2 are not equal
date1 and date3 are equal

Explanation

Here, we used an object-oriented approach to create the program. And, we imported the Date class using the below statement,

import java.util.Date;

Then we created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.

In the main() function, we created three objects of the Date class and compare them using the compareTo() method, and printed the appropriate message on the console screen.
