多線程常用操作方法

1、第14章：多線程編程多線程常用操作方法線程的命名和取得No.方法類型描述1public Thread(Runnable target, String name)構(gòu)造實(shí)例化線程對(duì)象，接收Runnable接口子類對(duì)象，同時(shí)設(shè)置線程名稱2public final void setName(String name)普通設(shè)置線程名字3public final String getName()普通取得線程名字范例：觀察線程的命名操作package cn.mldn.demo;class MyThread implements Runnable Overridepublic void run() System

2、.out.println(Thread.currentThread().getName();/ 當(dāng)前線程名稱public class ThreadDemo public static void main(String args) throws Exception MyThread mt = new MyThread();new Thread(mt, 線程A).start(); / 設(shè)置了線程的名字new Thread(mt).start(); / 未設(shè)置線程名字new Thread(mt, 線程B).start(); / 設(shè)置了線程的名字范例：觀察如下程序代碼package cn.mldn.d

3、emo;class MyThread implements Runnable Overridepublic void run() System.out.println(Thread.currentThread().getName();/ 獲取線程名稱public class ThreadDemo public static void main(String args) throws Exception MyThread mt = new MyThread();/ 線程類對(duì)象new Thread(mt, 線程對(duì)象).start(); / 設(shè)置了線程的名字mt.run(); / 對(duì)象直接調(diào)用run

4、()方法范例：子線程處理復(fù)雜邏輯package cn.mldn.demo;public class ThreadDemo public static void main(String args) throws Exception System.out.println(1、執(zhí)行操作任務(wù)一。);/ 主線程執(zhí)行new Thread()-/ 子線程負(fù)責(zé)統(tǒng)計(jì)int temp = 0 ;for (int x = 0 ; x / Runnable接口實(shí)例for (int x = 0; x 10; x+) System.out.println(Thread.currentThread().getName()

5、+ 、x = + x);try Thread.sleep(1000); / 暫緩1秒（1000毫秒）執(zhí)行 catch (InterruptedException e) / 強(qiáng)制性異常處理e.printStackTrace(); ;for (int num = 0; num System.out.println(【BEFORE】準(zhǔn)備睡覺(jué)10秒鐘的時(shí)間，不要打擾我);try Thread.sleep(10000); / 預(yù)計(jì)準(zhǔn)備休眠10秒System.out.println(【FINISH】睡醒了，開(kāi)始工作和學(xué)習(xí)生活); catch (InterruptedException e) System.

6、out.println(【EXCEPTION】睡覺(jué)被打擾了，壞脾氣像火山爆發(fā)一樣襲來(lái) ););thread.start(); / 線程啟動(dòng)Thread.sleep(1000); / 保證子線程先運(yùn)行1秒if (!thread.isInterrupted() / 該線程中斷？System.out.println(【INTERRUPT】敲鑼打鼓歡天喜地的路過(guò)你睡覺(jué)的地方！);errupt(); / 中斷執(zhí)行范例：線程強(qiáng)制執(zhí)行線程強(qiáng)制執(zhí)行：public final void join() throws InterruptedExceptionpackage cn.mldn.dem

7、o;public class ThreadDemo public static void main(String args) throws Exception Thread mainThread = Thread.currentThread() ; / 獲得主線程Thread thread = new Thread() - for (int x = 0 ; x 100 ; x +) if (x = 3) / 設(shè)置強(qiáng)制執(zhí)行條件try mainThread.join();/ 強(qiáng)制執(zhí)行線程任務(wù) catch (InterruptedException e) e.printStackTrace(); t

8、ry Thread.sleep(100);/ 延緩執(zhí)行 catch (InterruptedException e) e.printStackTrace();System.out.println(Thread.currentThread().getName() + 執(zhí)行、x = + x);,玩耍的線程) ;thread.start();for (int x = 0 ; x for (int x = 0 ; x 100 ; x +) if (x % 3 = 0) Thread.yield();/ 線程禮讓System.out.println(【YIELD】線程禮讓， + Thread.curre

9、ntThread().getName();try Thread.sleep(100); catch (InterruptedException e) e.printStackTrace();System.out.println(Thread.currentThread().getName() + 執(zhí)行、x = + x);,玩耍的線程) ;thread.start();for (int x = 0 ; x / 線程類對(duì)象for (int x = 0; x 10; x+) try Thread.sleep(1000);/ 暫緩執(zhí)行 catch (InterruptedException e) e.printStackTrace();System.out.println(Thread.currentThread().getName() + 執(zhí)行。);Thread threadA = new Thread(run, 線程對(duì)象A);/ 線程對(duì)象Thread threadB = new Thread(run, 線程對(duì)象B);/ 線程對(duì)象Thread threadC = new Thread(run, 線程對(duì)象C);/ 線程對(duì)象threadA.setPriority(Thread.MIN_PRIORITY);/ 修改線程優(yōu)先級(jí)threadB.se
