java线程池使用

java多线程

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

/**
* 线程池管理工具类

public class ThreadUtil {
/**
* 非固定数量线程池
*/
private static ExecutorService moreExecutorService = Executors.newCachedThreadPool();

/**
* 非固定数量线程池
* @param command
*/

for (int i=0; i < threadNum; i++) {

public void run() {

}
//Thread.sleep(2000) 利用sleep休眠;
