Kotlin select 多路复用 by Channel

@Test
    fun `test select channel`() = runBlocking<Unit> {
        val channels = listOf(Channel<Int>(), Channel<Int>())
        GlobalScope.launch {
            delay(100)
            channels[0].send(200)
        }
        GlobalScope.launch {
            delay(50)
            channels[1].send(100)
        }
        val result = select<Int?> {
            channels.forEach { channel ->
                channel.onReceive { it }
            }
        }
        println(result)
    }

如果修改下时间

 则结果打印200
