Cases mentioned by Hughes where there are differences include booting the JVM, creating NIO byte buffers, and dealing with threads and thread groups.
Hughes提到了下面一些区别:JVM启动、NIO字节缓冲区的创建、线程和线程组的处理等。
In addition, a thread group can also include other thread groups.
另外,一个线程组可以包含其他线程组。
The thread groups form a tree in which every thread group except the initial thread group has a parent.
树形结构中的线程组除了最顶层的都有自己的父线程组。
