Java as much as two-thread (implement Runnable)

/ ** 
* Create multi-threaded way: implement Runnable 
* 1. Create a class that implements the Runnable interface 
* 2. Implement Runnable class to implement abstract methods in: RUN () 
* 3. create an object implementation class 
* 4. this object is passed as an argument to the constructor of the thread class, create an object class thread 
* start by calling the object 5. thread class () 
* 
* 
* Comparative threads created in two ways. 
* Development: preferences: implement Runnable way 
* reason: the limitations of single inheritance is not the way to achieve 1 class 
* 2. manner better suited to handle the case of multiple threads have shared data. 
* 
* Contact: public class Thread implements Runnable 
same point *: Both approaches need to override run (), a logical statement will be executed in the thread run () in.

        T1 .start (); 

        // then start a thread, even within 100 to traverse 
        the thread T2 = new new the thread (mThread);
