Introduction to Kotlin (for Java Developers) - Cool Features - 6. Object declarations & top-level functions.kt

object ObjectDeclarationTest { // sort of like a Singleton
    var i = 5L

    fun doStuff() {
        println("hello!")
    }
}

fun test() { // no need to instantiate, everything is static
    ObjectDeclarationTest.i = 10L
    ObjectDeclarationTest.doStuff()
}

// We can also have functions WITHOUT a class ("top-level functions")
fun myFun() { println("Hello!") }
class BestClass {
    fun someMethod() {
        myFun()
        test()
    }
}
