How to use Object Approach In Scala

Below is the Scala program to qualify methods as static:

Scala

// Define an object with static methods
object MathUtils {
  def add(x: Int, y: Int): Int = {
    x + y
  }

  def subtract(x: Int, y: Int): Int = {
    x - y
  }
}

// Main program
object Main {
  def main(args: Array[String]): Unit = {
    println("Addition: " + MathUtils.add(5, 3))
    println("Subtraction: " + MathUtils.subtract(10, 4))
  }
}

Output:

Explanation:

In this example, MathUtils object contains two static methods add and subtract, which can be called directly without creating an instance of MathUtils. The Main object demonstrates how to use these static methods.

How to Qualify Methods as Static in Scala?

In this article, we will learn how to qualify methods as static in Scala. you declare a method as static using the object keyword instead of the class keyword. By defining a method within an object, you create a singleton object that can hold static methods.

Syntax:

object MyClass {

def myStaticMethod(): Unit = {

// Your static method implementation here

println(“This is a static method”)

}

}

Here, myStaticMethod is a static method because it is defined within the MyClass object. You can access it without creating an instance of MyClass.
