Thread的方法，属性

创建一个指定名字的线程

若不指定名字，JVM会给定一个名字；

private static class MyRunnable implements Runnable{
    @Override
    public void run() {
        while (true) {
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}
public static void main(String[] args) {
    MyRunnable myRunnable = new MyRunnable();
    Thread thread = new Thread(myRunnable);
    thread.start();
    
    Thread thread1 = new Thread(myRunnable, "我是指定名字的线程");
    thread1.start();;
}

使用JConsole工具查看线程名称

属性

public static void main(String[] args) {
    Thread currentThread = Thread.currentThread();

    System.out.println(currentThread.getName());
    System.out.println(currentThread.getId());
    System.out.println(currentThread.getState());
    System.out.println(currentThread.getPriority());
    System.out.println(currentThread.isDaemon());
    System.out.println(currentThread.isAlive());
    System.out.println(currentThread.isInterrupted());
    System.out.println(currentThread.getThreadGroup());
}
//结果
main//线程名称
1//线程ID
RUNNABLE//线程状态
5//线程优先级，越高越好
false//是否是精灵(守卫)线程
true//是否活着
false//是否有其他线程要改线程die
java.lang.ThreadGroup[name=main,maxpri=10]//线程组

JAM会将创建的线程分别放入线程组中；
