一个简单的多线程示例

public class ThreadTestCase extends Thread {private static int share = 0;@Overridepublic void run() {share = share + 1;System.out.println(share);try {ThreadTestCase.sleep(2000);} catch (InterruptedException e) {e.printStackTrace();}System.out.println(share);}public static void main(String[] args) {ThreadTestCase t1 = new ThreadTestCase();ThreadTestCase t2 = new ThreadTestCase();t1.start();t2.start();}}

运行结果如下：
