threadId:10,threadName:thread-a 3.2.4、setPriority() setPriority()方法的作用是设置线程的优先级,取值范围:1～ 10,与此对应的还有getPriority()方法,用于获取线程的优先级。优先级越高,拥有优先获取 CPU 执行的优势。 换句话说,当有两个线程在等待 CPU 执行时,优先级高的线程越容易被 CPU 选择执行。 样例...

- locked <0x1cfcdc00> (a java.lang.Object) at java.lang.Thread.run(Thread.java:662) 可以发现t1和t2都处在WAITING (on object monitor),进入等待状态的原因是调用了in Object.wait()。通过J.U.C包下的锁和条件队列,也是这个效果,大家可以自己实践下。 显示TIMED_WAITING状态 package jstack; import j...
