Introduction to Kotlin (for Java Developers) - Cool Features - 11. Single-expression functions.kt

fun awesomeMethod(a: Int, b: Int) = a + b - 101 // No need to specify return type or use "return" keyword

// This can come in handy when combining it with Kotlin's expression features
fun totallyAmazingMethod(str: String?, a: Int) =
    str?.uppercase() ?:
        if (a == 5) "some string" else "some other string"

// Can be helpful when using functional programming...
