如何计算线程的线程池[Kotlin]？

import java.util.concurrent.Executors
import java.util.concurrent.ThreadPoolExecutor

fun main() {
    // 创建一个线程池
    val threadPool: ThreadPoolExecutor = Executors.newFixedThreadPool(5) as ThreadPoolExecutor

    // 提交任务到线程池
    for (i in 0 until 10) {
        threadPool.execute {
            println("Task $i is running on thread ${Thread.currentThread().name}")
        }
    }

    // 关闭线程池
    threadPool.shutdown()
}
