 1     默认构造方法 分配一个新的线程对象
 2     这个构造器和上面的#Thread(ThreadGroup,Runnable,String)方法有相同作用，其中线程名是新生成的名称
 3     自动生成名称的格式为Thread-n，其中n是一个整数
 4     /**
 5      * Allocates a new {@code Thread} object. This constructor has the same
 6      * effect as {@linkplain #Thread(ThreadGroup,Runnable,String) Thread}
 7      * {@code (null, null, gname)}, where {@code gname} is a newly generated
 8      * name. Automatically generated names are of the form
 9      * {@code "Thread-"+}<i>n</i>, where <i>n</i> is an integer.
10      */
11     public Thread() {
12         init(null, null, "Thread-" + nextThreadNum(), 0);
13     }

          测试代码 输出空
1         Thread name = new Thread();
2         name.run();
