Java 线程的生命周期完整实例分析
本文实例讲述了Java线程的生命周期。分享给大家供大家参考，具体如下：
一代码
/**
*@Title:ThreadStatus.java
*@Description:TODO(演示线程的生命状态)
*/
importjava.util.concurrent.locks.Lock;
importjava.util.concurrent.locks.ReentrantLock;
importjava.util.concurrent.TimeUnit;
publicclassThreadStatus
{
privatestaticLocklock=newReentrantLock();
publicstaticvoidmain(String[]args)
{
newThread(newTimeWaiting(),"TimeWaitingThread").start();
newThread(newWaiting(),"WaitingThread").start();
//使用两个Blocked线程，一个获取锁，一个被阻塞
newThread(newBlocked(),"BThread-1").start();
newThread(newBlocked(),"BThread-2").start();
newThread(newSync(),"SyncThread-1").start();
newThread(newSync(),"SyncThread-2").start();
}
//该线程不断地进入随眠
staticclassTimeWaitingimplementsRunnable
{
publicvoidrun(){
while(true)
{
try{
TimeUnit.SECONDS.sleep(5);
System.out.println("IamTimeWaitingThread:"+Thread.currentThread().getName());
}catch(InterruptedExceptione){}
}
}
}
//该线程在Waiting.class实例上等待
staticclassWaitingimplementsRunnable
{
publicvoidrun()
{
while(true)
{
synchronized(Waiting.class)
{
try{
System.out.println("IamWaitingThread:"+Thread.currentThread().getName());
Waiting.class.wait();
}catch(InterruptedExceptione){
e.printStackTrace();
}
}
}
}
}
//该线程在Blocked.class实例上加锁后，不会释放该锁
staticclassBlockedimplementsRunnable
{
publicvoidrun()
{
synchronized(Blocked.class)
{
while(true)
{
try{
System.out.println("IamBlockedThread:"+Thread.currentThread().getName());
TimeUnit.SECONDS.sleep(5);
}catch(InterruptedExceptione){}
}
}
}
}
//该线程用于同步锁
staticclassSyncimplementsRunnable
{
publicvoidrun(){
lock.lock();
try{
System.out.println("IamSyncThread:"+Thread.currentThread().getName());
TimeUnit.SECONDS.sleep(5);
}catch(InterruptedExceptione){}
finally{
lock.unlock();
}
}
}
}
二运行
IamWaitingThread:WaitingThread
IamBlockedThread:BThread-1
IamSyncThread:SyncThread-1
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
IamSyncThread:SyncThread-2
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
IamTimeWaitingThread:TimeWaitingThread
IamBlockedThread:BThread-1
