Java线程中start()和run()的区别

run():不管是通过实现Runnable接口还是继承Thread类（其实Thread中的run方法也是调用了Runnable接口的run方法），调用run()方法仅仅是相当于调用了一个方法，没有启用新的线程。
start():会启动一个新线程，运行重写的run(）代码。
例子：public class MyThread {

public static void main(String[] args) {
SThread sThread = new SThread();
sThread.run();
sThread.start();
S2Thread s2Thread = new S2Thread();
s2Thread.run();
}
}
class SThread extends Thread {
@Override
public void run() {
System.out.println(Thread.currentThread().getName() + " run method run() by Class Thread");
}
}
class S2Thread implements Runnable {
@Override
public void run() {
System.out.println(Thread.currentThread().getName() + " run method run() by Interface Runnable");
}
}结果：main run method run() by Class Thread
Thread-0 run method run() by Class Thread
main run method run() by Interface Runnable参考文章：线程中run()和start()的区别
