[Kotlin] Pass Kotlin Array as Java variable length argument [Java]

things to do

Pass Kotlin's ʻArray` to a function like this:

void hoge(HogeClass... hogeClasses) {
  /*abridgement*/
}

manner

You can do this by prepending * to ʻArray`, as shown below.

val hogeList: Array<HogeClass> = //Initialization omitted

//call
hoge(*hogeList)

What you are doing

The * supplemented at the beginning is the Spread operator, which is passed by expanding ʻArray`.

In Kotlin you can use variadic arguments by declaring fuga (vararg hoge: HogeClass), but you have to do the same when passing ʻArray` here.
