kotlin创建简单多线程的3种方式

import kotlin.concurrent.threadfun main(args: Array) {//方式1object : Thread() {override fun run() {sleep(1500)val ct = currentThread()println("$ct")}}.start()// 方式2val t = Thread {Thread.sleep(1000)val ct = Thread.currentThread()println("$ct")}t.isDaemon = falset.name = "my-thread-"t.priority = 2t.start()// 方式3thread(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]
