代码示例：

//Thread里面的常见属性
    public class ThreadDemo6 {
        
        public static void main(String[] args) throws InterruptedException {
        
            Thread t = new Thread("xc"){
        
                @Override
                public void run() {
        
                    System.out.println(Thread.currentThread().getName());
                    //Thread.currentThread()获取到当前线程的实例
                    //获取到线程的名字
                    for (int i= 0; i<10; i++){
        
                        try {
        
                            Thread.sleep(1000);
                        } catch (InterruptedException e) {
        
                            e.printStackTrace();
                        }
                    }
                    //run方法执行过程中就代表着系统内线程的生命周期
                    System.out.println("线程要退出了");
                }
            };
    
            //这四个只要线程创建好就不变了
            System.out.println(t.getName());
            System.out.println(t.getId());
            System.out.println(t.getPriority());
            System.out.println(t.isDaemon());
            //这两个会发生改变
            System.out.println(t.isAlive());
            System.out.println(t.isInterrupted());
            System.out.println(t.getState());
    
    
            t.start();
    
            while (t.isAlive()){
        
                System.out.println("xc正在运行");
                System.out.println(t.getState());
                System.out.println(t.isInterrupted());
                Thread.sleep(300);
    
            }
        }
    }

运行结果：
