kotlin创建简单多线程的3种方式

import kotlin.concurrent.thread

fun main(args: Array<String>) {
    //方式1
    object : Thread() {
        override fun run() {
            sleep(1500)
            val ct = currentThread()
            println("$ct")
        }
    }.start()

    // 方式2
    val t = Thread {
        Thread.sleep(1000)
        val ct = Thread.currentThread()
        println("$ct")
    }
    t.isDaemon = false
    t.name = "my-thread-"
    t.priority = 2
    t.start()

    // 方式3
    thread(start = true, isDaemon = false, name = "my-thread--", priority = 3) {
        Thread.sleep(500)
        val ct = Thread.currentThread()
        println("thread() : $ct")
    }
}

输出：

thread() : Thread[my-thread--,3,main]
Thread[my-thread-,2,main]
Thread[Thread-0,5,main]
