经过测试笔者选择的Oracle OpenJDK 17,stackSize与递归深度关系不是很大,有的时候甚至成反比。 守护线程 Java中通过将线程设置为守护线程(daemon thread)来指示该线程为守护线程。守护线程在没有用户线程(也就是剩余线程均为守护线程,JVM会退出)继续运行时会自动终止。这对于执行后台任务或提供服务的线程非常有用,因为...
Each thread in Java has its own name which is set by the JVM by default. Although there are many other attributes associated to the thread like: id, priority etc. we can get name of a thread by calling getName() method of Thread class. If we wish to set new name of the thread ...

Thread类位于java.lang包,JDK1.0引入。在HotSpot虚拟机中,线程使用的是基于操作系统的1 : 1的内核实现模型来创建线程,线程的创建、调度、执行、销毁等由内核进行控制,调度过程通过抢占式策略进行调度。 生命周期 Java语言定了线程生命周期的6种状态,在任意时刻线程只能处于一种状态,Java中提供了特定的API,在某些场景...
如果没有另外说明,则在同一个ThreadGroup中一律使用Executors.defaultThreadFactory()创建线程,并且这些线程具有相同的NORM_PRIORITY优先级和非守护进程状态。通过提供不同的 ThreadFactory,可以改变线程的名称、线程组、优先级、守护进程状态,等等。如果从newThread返回 null 时ThreadFactory未能创建线程,则执行程序将继续运行,...
Java使用的线程调度方式是抢占式调度,但是可以通过线程优先级来给操作系统"建议"给某些线程多分配一点执行时间。 Java语言一共设置了10个级别的线程优先级(Thread.MIN_PRIORITY至Thread.MAX_PRIORITY),在两个线程同时处于Ready状态时,优先级越高的线程越容易被系统选择执行。但是操作系统的线程优先级与Ja...
