線程的停止

關(guān)于軍隊(duì)這一塊沒(méi)有設(shè)置他的具體結(jié)束時(shí)間，怎么能確定這兩個(gè)線程會(huì)結(jié)束呢？什么時(shí)候結(jié)束呢，KeepRunning這個(gè)值什么時(shí)候會(huì)被調(diào)用呢，DeBug不出來(lái)啊，求解

在舞臺(tái)這個(gè)線程里面將兩個(gè)軍隊(duì)線程對(duì)象的KeepRunning屬性設(shè)置為false，從而結(jié)束了兩個(gè)軍隊(duì)線程。

ArmyRunnable?armyA?=?new?ArmyRunnable();
		ArmyRunnable?armyB?=?new?ArmyRunnable();
		Thread?threadArmyA=new?Thread(armyA,"armyA");
		Thread?threadArmyB=new?Thread(armyB,"armyB");
		threadArmyA.start();
		threadArmyB.start();
	????try?{
			Thread.sleep(50);
		}?catch?(InterruptedException?e)?{
			//?TODO?Auto-generated?catch?block
			e.printStackTrace();
		}
	????armyA.keepRunning=false;?//結(jié)束了軍隊(duì)A的線程
	????armyB.keepRunning=false;?//結(jié)束了軍隊(duì)B的線程

在軍隊(duì)線程里面，keepRunning需用volatile修飾，表示它可以被不同線程訪問(wèn)和修改。

即：
