java - How to run threads without using Runnable implementations? -

i found following excerpt in java textbook:

"i've seen examples don't use separate  runnable implementation, instead make  subclass of thread , override thread's runo  method. way,you call thread's no-arg  constructor when make new thread;  thread t = new thread(); //no runnable" 

shouldn't last line be

thread t = new <some class extends thread class , on rides run method>(); 

am correct?

could provide sample code illustrates above excerpt?

you correct.

if create instance of thread without overriding run() of supplying runnable, thread execute default empty run() method.

i wonder if quote accurate, mentions sub-classing thread, code thread t = new thread(); doesn't.
