Kotlin Class: Calculate the total cost of a product

Kotlin Class: Exercise-10 with Solution

Write a Kotlin program that creates a class 'Product' with properties for name, price, and quantity. Calculate the total cost of the product with a function.

Sample Solution:

Kotlin Code:

class Product(
    val name: String,
    val price: Double,
    val quantity: Int
) {
    fun calculateTotalCost(): Double {
        return price * quantity
    }
}

fun main() {
    val product = Product("Desktop", 2000.0, 4)
    val totalCost = product.calculateTotalCost()
    println("Total Cost: $totalCost")
}

Sample Output:

Total Cost: 8000.0

Explanation:

In the above exercise -

• In this program, we define a class "Product" with three properties: name, price, and quantity, representing the product's name, price, and quantity.
• The class includes a function "calculateTotalCost()" that calculates the total cost of the product by multiplying the price by the quantity.
• In the "main()" function, we create an instance of the Product class named product with the name "Desktop", a price of 2000.0, and a quantity of 4. We then call the calculateTotalCost function on the product object and store the result in the totalCost variable.
• The println function is used to print the total cost calculated.
