先创建一个 Runnable 子类
public static void main(String[] args) { Thread thread = new Thread(new Runnable() { final Object lock = new Object(); public void run() { synchronized (lock) { try { lock.wait(); } catch (InterruptedException e) { } } } }); thread.start(); System.out.println(thread.getName()+" state :"+thread.getState()); try { Thread.sleep(1000L); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println(thread.getName()+" state :"+thread.getState()); }测试方法
public static void main(String[] args) { BlockedStateRun blockedStateRun = new BlockedStateRun(); Thread thread1= new Thread(blockedStateRun); Thread thread2= new Thread(blockedStateRun); thread1.setName("First"); thread1.start(); thread2.setName("Second"); thread2.start(); try { Thread.sleep(200L); System.out.println(thread1.getName()+"::"+thread1.getState()); System.out.println(thread2.getName()+"::"+thread2.getState()); } catch (InterruptedException e) { e.printStackTrace(); } }最后的运行结果：
