[Java] View Plain copy/* Demand: implement a ticket sales program the second way to create a thread: Implement Runnable interface steps: 1, the definition class implements the Runnable interface     2, overrides the Run method in the Runnable interface Store the code that the thread is running in the Run method 3, creating the Thread object via the thread class 4, the Runnable interface's subclass object is passed as the actual parameter to the thread class's constructor Why would you pass a subclass object in the Runnable interface to the thread's constructor because, The object that the custom run method belongs to is the subclass object of the Runnable interface So let the thread specify the run method of the specified object. You must be clear about which object the Run method belongs to.     5, calling the thread class Start method opening the thread and calling the Run method of the Runnable interface subclass Differences in implementation and inheritance: implementation benefits: Avoid the limitations of single inheritance define recommendations using implementation two ways to differentiate: inheritance thread: Thread code is stored in ThreaD Subclass the Run method. Implementation runnable: Thread code stored in the interface of the subclass of the Run method, */ class tick implements runnable { private int tick = 50; public void run () { while (true) { if (tick > 0) system.out.println ( thread.currentthread (). GetName () + " sail --" + tick--"; } } } class tickdemo { &nBsp; public static void main (String []args) { tick t = new tick (); thread t1 = new thread (t ); thread t2 = new thread (t); thread t3 = new thread (t); thread t4 = new thread (t); t1.start (); t2.start (); T3.start (); t4.start (); }
