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...
Athreadis a thread of execution in a program. The Java Virtual Machine allows an application to have multiple threads of execution running concurrently. Every thread has a priority. Threads with higher priority are executed in preference to threads with lower priority. Each thread may or may not...

一.文件准备 但我们一般安装的jdk都是SunJDK(OracleJDK),它只提供java和javax下的源代码,如果我们需要看sun.simc.Launcher这样的类的时候还是没有源代码,我们可以通过下载OpenJDK的源码来查看。 下载地址:http://hg.openjdk.java.net 找到对应的jdk版本,比如jdk8 http...jdk...
If not otherwise specified, a Executors.defaultThreadFactory() is used, that creates threads to all be in the same ThreadGroup and with the same NORM_PRIORITY priority and non-daemon status. By supplying a different ThreadFactory, you can alter the thread's name, thread group, priority, ...

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...
3. Task priorities in the Linux kernel Linux uses separate priority ranges for normal and real time tasks. For normal tasks a priority range (or nice value) of -20 to +19 is used. Lower nice corresponds to higher priority. In other words the task is being less nicer to other tasks in...
