This article will explain in detail how to use Java multithreading to create Thread objects in mail. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Java multithreading has a lot of knowledge that we need to learn, and we still need to be close to practice when learning. Let's take a detailed look at the use of Java multithreading. We then modify the ThreadDemo1 to create four Thread objects in the main method:

Public class ThreadDemo1 {public static void main (String [] args) {new ThreadTest (). Start ();}} class ThreadTest extends Thread {private int ticket = 100; public void run () {while (true) {if (ticket > 0) {System.out.println (Thread.currentThread (). GetName () + "is saling ticket" + ticket-);} else {break }

Did you achieve your goal?

As a result, each ticket number was printed four times, that is, the four threads each sold their own 100 tickets instead of the common 100 tickets. How did this happen? What we need is that multiple threads deal with the same resource, and one resource can only correspond to one object. In the above program, we created four ThreadTest objects, which is equivalent to creating four resources, each of which has 100tickets, and each thread is dealing with its own resource alone.

After these experiments and analysis, it can be concluded that in order to implement this railway ticketing program, we can only create one resource object, but we need to create multiple threads to deal with the same resource object. and the same program code is running on each thread. Review the process of writing Java multithreading using interfaces.

Public class ThreadDemo1 {public static void main (String [] args) {ThreadTest t = new ThreadTest (); new Thread (t). Start ();}} class ThreadTest implements Runnable {private int tickets = 100 Public void run () {while (true) {if (tickets > 0) {System.out.println (Thread.currentThread () .getName () + "is saling ticket" + tickets-);}

In the above program, Java multithreading is created. Each thread calls the run () method in the same ThreadTest object and accesses the instance of the variable (tickets) in the same object. This program meets our needs. Multiple notepad programs can be started on Windows, that is, multiple processes use the same notepad program code.

On how to use Java multithreading in mail to create Thread objects to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
