1.线程的等待与唤醒wait（）和notify（）；
public class Test{ public static void main(String[]args){ Thread thread1=new NewThread("t1"); synchronized(thread1){ System.out.println(Thread.currentThread().getName()+" is running"); thread1.start(); System.out.println(Thread.currentThread().getName()+" is running"); try{ thread1.wait(); System.out.println(Thread.currentThread().getName()+" is running"); }catch(InterruptedException e){ e.printStackTrace(); } } } } class NewThread extends Thread{ public NewThread(String name){ super(name); } public void run(){ synchronized(this){ System.out.println(Thread.currentThread().getName()+":"+"notify"); this.notify(); } } }
线程thread1是在main这个主线程上创建的，所以一开始运行的时主线程main，当thread1调用start方法，处于就绪状态，直到main被阻塞，cpu允许threadd1执行，会输出thread1：notify，直到thread1调用wait（）方法被进行无线等待，最后main()进行运行。
如下程序：main运行→thread1调用start（）方法运行→然后让thread1调用wait（）方法进行等待→主线程main运行.
public class Test{ public static void main(String[]args){ Thread thread1=new NewThread("t1"); synchronized(thread1){ try{ System.out.println(Thread.currentThread().getName()+":"+"running"); //start thread1 thread1.start(); //thread1 wait thread1.wait(10000); System.out.println(Thread.currentThread().getName()+":"+"running"); }catch(InterruptedException e){ e.printStackTrace(); } } } } class NewThread extends Thread{ public NewThread(String name){ super(name); } public void run(){ synchronized(this){ System.out.println(Thread.currentThread().getName()+":"+"running"); } } }
