thread.currentthread()

Question

这串代码位于Think In Java中的并发章节

如图，想问一下大家，这个pool-1-thread-6，pool-1-thread-2，pool-1-thread-3，后面的1或者10代表的是什么意思？？？百思不得其解

Answer 1

public String toString() {
        ThreadGroup group = getThreadGroup();
        if (group != null) {
            return "Thread[" + getName() + "," + getPriority() + "," +
                           group.getName() + "]";
        } else {
            return "Thread[" + getName() + "," + getPriority() + "," +
                            "" + "]";
        }
    }

那个数字代表优先级，(min)1-10(max).
