Java- 实现多线程的两种方法

1. Extending the Thread class
2. Implementing the Runnable Interface

code example

// Java code for thread creation by extending 
// the Thread class 
class MultithreadingDemo extends Thread 
{ 
    public void run() 
    { 
        try
        { 
            // Displaying the thread that is running 
            System.out.println ("Thread " + 
                Thread.currentThread().getId() + 
                " is running"); 

        } 
        catch (Exception e) 
        { 
            // Throwing an exception 
            System.out.println ("Exception is caught"); 
        } 
    } 
} 

// Main Class 
public class Multithread 
{ 
    public static void main(String[] args) 
    { 
        int n = 8; // Number of threads 
        for (int i=0; i<8; i++) 
        { 
            MultithreadingDemo object = new MultithreadingDemo(); 
            object.start(); 
        } 
    } 
} 

// Java code for thread creation by implementing 
// the Runnable Interface 
class MultithreadingDemo implements Runnable 
{ 
    public void run() 
    { 
        try
        { 
            // Displaying the thread that is running 
            System.out.println ("Thread " + 
                                Thread.currentThread().getId() + 
                                " is running"); 

        } 
        catch (Exception e) 
        { 
            // Throwing an exception 
            System.out.println ("Exception is caught"); 
        } 
    } 
} 

// Main Class 
class Multithread 
{ 
    public static void main(String[] args) 
    { 
        int n = 8; // Number of threads 
        for (int i=0; i<8; i++) 
        { 
            Thread object = new Thread(new MultithreadingDemo()); 
            object.start(); 
        } 
    } 
}
