This article mainly explains "what are the two ways to start threads in Java". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what are the two ways to start threads in Java.

The essence of threading: that is, a road changes from a single lane to a multi-lane, thus avoiding traffic jams

Method 1:

Public class StartRun extends Thread {@ Override / / Thread entry point public void run () {/ / Thread body for (int I = 0; I < 20; iThread +) {System.out.println ("2");} public static void main (String [] args) {/ / create subclass object StartRun st=new StartRun (); / / start thread st.start (); / / thread () Note that when using the run () method, it can only be executed sequentially, even if it inherits thread for (int I = 0; I < 20; iTunes +) {System.out.println ("1");}

The output result only depends on the allocation of cpu, so the output order of 1 and 2 is not unique.

Method two

Public class StartRun02 implements Runnable {@ Override / / Thread entry point public void run () {/ / Thread body for (int I = 0; I < 20; iThread +) {System.out.println ("2");}} public static void main (String [] args) {/ / create implementation class object StartRun02 thread= new StartRun02 (); / / create proxy class object Thread t=new Thread (thread); t.start () / / it is also possible to new Thread (new StartRun02 ()) .start () for (int I = 0; I < 20; iTunes +) {System.out.println ("1");}

It is recommended to use method 2-it is better to use implementation rather than inheritance. After all, inheritance can only inherit one parent class, while implementation can implement multiple interfaces

Thank you for your reading, the above is the content of "what are the two ways for Java to start threads". After the study of this article, I believe you have a deeper understanding of what the two methods of Java start threads are, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
