:
val future1: CompletableFuture<String> = CompletableFuture.supplyAsync {
println("This is your thread 1 code")
"<html><head><title>"
}
val future2: CompletableFuture<String> = CompletableFuture.supplyAsync {
println("This is your thread 2 code")
if (Random().nextBoolean()) throw RuntimeException("Failed")
"Title!</title></html></head>"
}
future1.thenCombine(future2, {result1, result2 -> result1 + result2}).whenComplete { s, throwable ->
if (throwable != null) {
println("failed")
} else {
println("done with $s")
}
}
그리고 코 틀린 1.1에서 당신이 할 수 쓰기보다 읽기 방법이 코드가 될 것이다 :
async {
try {
val s1 = await(future1)
val s2 = await(future2)
println(s1 + s2)
} catch (e: Exception) {
println("failed")
}
}
