Kotlin Class: MathConstants object for Mathematical constants
Kotlin Class: Exercise-20 with Solution
Write a Kotlin program that creates an object declaration 'MathConstants' that provides constants for mathematical calculations such as PI and E.
Sample Solution:
Kotlin Code:
object MathConstants {
val PI = 3.14159
val E = 2.71828
}
fun main() {
println("Value of PI: ${MathConstants.PI}")
println("Value of E: ${MathConstants.E}")
}
Sample Output:
Value of PI: 3.14159 Value of E: 2.71828
Explanation:
In the above exercise -
- First we define an object declaration "MathConstants" which serves as a singleton object. Inside the MathConstants object, we define two properties PI and E to hold mathematical constants.
- In the "main()" function, we access PI and E values using the MathConstants object and print them.
