Use the RuPengGame engine package to create a game form such as Peng game engine package Thread Runnable ticket selling instance and rupenggamerunnable

 

Package com. swift; import com. rupeng. game. GameCore; // import the game engine package

// Implement the Runnable interface public class Game_RuPeng implements Runnable {public static void main (String [] args) {GameCore. start (new Game_RuPeng (); // generate the game object and let the engine start it} // Override the run () method in the interface to control the game @ Override public void run () {GameCore. setGameSize (1024,768); // set the size of the game window GameCore. setGameTitle ("game window"); // set the game window title GameCore. pause (3000); // set the game window to stay for 3 seconds }}

The following example describes the implements Runnable interface.

Taking the ticket selling program as an example, the Thread class is used to complete:

Package com. swift; class SellTickets extends Thread {private int ticket = 10; public void run () {for (int I = 0; I <20; I ++) {if (this. ticket> 0) {System. out. println ("selling tickets: ticket" + this. ticket --) ;}} public static void main (String [] args) {SellTickets mt1 = new SellTickets (); SellTickets mt2 = new SellTickets (); sellTickets mt3 = new SellTickets (); mt1.start (); // each thread sells 10 tickets, with a total of 30 mt2.start () tickets (); // but there are actually only 10 tickets, and each thread sells its own mt3.start (); // Resource Sharing Failed }}

 

If Runnable is used, resources can be shared. The following is an example:

Package com. swift; class SellTickets2 implements Runnable {private int ticket = 10; public void run () {for (int I = 0; I <20; I ++) {if (this. ticket> 0) {System. out. println ("selling tickets: ticket" + this. ticket --) ;}} public static void main (String [] args) {SellTickets2 mt = new SellTickets2 (); new Thread (mt ). start (); // The same mt, but not in the Thread. If the same new Thread (mt) is used ). start (); // an instantiated object mt, and an exception new Thread (mt) will occur ). start ();}}

Although there are currently three threads in the program, a total of 10 tickets are sold. That is to say, using Runnable to implement multithreading can achieve resource sharing.

In java, You can implement multithreading in two ways. One is to inherit the Thread class, the other is to implement the Runnable interface, and the Thread class is defined in the java. lang package. As long as a class inherits the Thread class and overwrites the run () method in this class, it can implement multi-threaded operations. However, a class can only inherit one parent class, which is the limitation of this method.
