本文实例分析了java多线程中的volatile和synchronized用法。分享给大家供大家参考。具体实现方法如下：

public class Volatiletest extends Thread {

    private static int count = 0;

    public void run() {
        count++;
    }

    public static void main(String[] args) {
        Thread threads[] = new Thread[10000];
        for (int i = 0; i < threads.length; i++) {
            threads[i] = new Volatiletest();
        }
        for (int i = 0; i < threads.length; i++) {
            threads[i].start();
        }
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println(count);
    }
}
