Scala Program: MathConstants object with PI and E constants

Scala OOP Exercise-11 with Solution

Write a Scala program that creates an object MathConstants with constants for mathematical calculations such as PI and E.

Sample Solution:

Scala Code:

object MathConstants {
  val PI: Double = 3.14159
  val E: Double = 2.71828
}

object MathConstantsApp {
  def main(args: Array[String]): Unit = {
    println(s"The value of PI is: ${MathConstants.PI}")
    println(s"The value of E is: ${MathConstants.E}")
  }
}

Sample Output:

The value of PI is: 3.14159
The value of E is: 2.71828

Explanation:

In the above exercise, the "MathConstants" object is defined with two properties 'PI' and 'E'. These properties are defined as val and assigned the corresponding constant values.

The "MathConstantsApp" object contains the "main()" method where we can test functionality. It simply prints the values of 'PI' and 'E' using the "MathConstants" object.
