Kotlin Class: Enum class Color for Object color representation

Last update on December 20 2024 12:55:11 (UTC/GMT +8 hours)

Write a Kotlin program that creates an enum class 'Color' with values for different colors. Use the enum class to represent an object's color.

Sample Solution:

Kotlin Code:

enum class Color {
    RED, GREEN, BLUE, BLACK, ORANGE
}

data class Object(val name: String, val color: Color)

fun main() {
    val plants = Object("Plants", Color.GREEN)
    val cloud = Object("Cloud", Color.BLACK)
    val flowers = Object("Flowers", Color.RED)

    println("${plants.name} color: ${plants.color}")
    println("${cloud.name} color: ${cloud.color}")
    println("${flowers.name} color: ${flowers.color}")
}

Sample Output:

Plants color: GREEN
Cloud color: BLACK
Flowers color: RED

Explanation:

In the above exercise -

• First we define an enum class "Color" with different color values such as RED, GREEN, BLUE, BLACK, and ORANGE.
• We also define a data class "Object" with properties name and color. The color property is of type Color in our enum class.
• In the "main()" function, we create instances of the Object class representing different objects with their respective colors using enum values.
• Finally, we print the name and color of each object using the println statement.
