刚刚在APIdoc看的 ：分配新的 Thread 对象，以便将 target 作为其运行对象，将指定的 name 作为其名称，作为 group 所引用的线程组的一员，并具有指定的堆栈尺寸

这个方法我们很少直接用，源码里面有很多，给你找一个，你看一下：
类：TimerQueue
synchronized void start() {
if (running) {
throw new RuntimeException("Can't start a TimerQueue " +
"that is already running");
}
else {
final ThreadGroup threadGroup =
AppContext.getAppContext().getThreadGroup();
java.security.AccessController.doPrivileged(
new java.security.PrivilegedAction() {
public Object run() {
Thread timerThread = new Thread(threadGroup, TimerQueue.this,
"TimerQueue");
timerThread.setDaemon(true);
timerThread.setPriority(Thread.NORM_PRIORITY);
timerThread.start();
return null;
}
});
running = true;
}

在类Executors中：
/**
* The default thread factory
*/
static class DefaultThreadFactory implements ThreadFactory {
static final AtomicInteger poolNumber = new AtomicInteger(1);
final ThreadGroup group;
final AtomicInteger threadNumber = new AtomicInteger(1);
final String namePrefix;
DefaultThreadFactory() {
SecurityManager s = System.getSecurityManager();
group = (s != null)? s.getThreadGroup() :
Thread.currentThread().getThreadGroup();
namePrefix = "pool-" +
poolNumber.getAndIncrement() +
"-thread-";
}
public Thread newThread(Runnable r) {
Thread t = new Thread(group, r,
namePrefix + threadNumber.getAndIncrement(),
0);
if (t.isDaemon())
t.setDaemon(false);
if (t.getPriority() != Thread.NORM_PRIORITY)
t.setPriority(Thread.NORM_PRIORITY);
return t;
}

你问的问题跟你给的代码，一点关系都没有，是不是想来随便混技术分啊？
