Program to calculate simple interest in kotlin

Kotlin Program to calculate simple interest. Here more solutions.

//  Kotlin program for
//  Calculate simple interest
class Interest {
    companion object {
        // Method which is take three parameters
        // And calculates that simple interest
        // Here time is form in year
        // rate is form of annual interest rate
        fun simpleInterest(principle : Number, 
                           time : Number, 
                           rate : Number) : Unit
        {
            // Display parameters values
            println("Principal : " + principle);
            println("Time : " + time);
            println("Rate : " + rate);
            // Calculate interest
            val amount : Double = (principle.toDouble() * 
                                   time.toDouble() * 
                                   rate.toDouble()) / 100;
            // Display amount
            println("Simple Interest : " + amount + "\n");
        }
    }
}
fun main(args : Array<String>) : Unit
{
  // Test Cases
  Interest.simpleInterest(1500, 3, 7.3);
  Interest.simpleInterest(170.4, 7, 3.4);
}

Output

Principal : 1500
Time : 3
Rate : 7.3
Simple Interest : 328.5

Principal : 170.4
Time : 7
Rate : 3.4
Simple Interest : 40.55519999999999
