如何在Kotlin中用单行值声明列表？

Question

How can i declare a list in single line? In groovy i can do something like below

def l = ['a', 'b', 'c'];

What is the kotlin equivalent for this?

Answer 1

You can easily find it in Kotlin documentation :

val list = listOf('a', 'b', 'c')

/** Returns a new read-only list of given elements.  
 *  The returned list is serializable (JVM).
 */
public fun <T> listOf(vararg elements: T): List<T> 
        = if (elements.size > 0) elements.asList() else emptyList()
