2 min readMar 11, 2024
Kotlin is a statically typed programming language designed for the JVM (Java Virtual Machine) that is more modern and concise than Java. Kotlin’s many powerful features make it an attractive option for both beginners and experienced programmers.
A detailed look at some of Kotlin’s powerful features with examples:
1. Data Classes:
Data classes make it easy to create simple data transfer objects. With a few lines of code, you can use the data
keyword which automatically generates all the necessary boilerplate code.
data class Queen(val name: String, val age: Int)
val queen = Queen("Taylor", 34)
println(queen.name) // Prints "Taylor"
println(queen.age) // Prints 34
2. Function Types:
Function types make it easier to work with functions, such as lambda expressions and higher-order functions.
val sum: (Int, Int) -> Int = { a, b -> a + b }
val result = sum(1, 3) // Prints 4
