這兩個的區別Thread是我new了好幾個對象，所以要不static 讓他們使用一個對象，Runnable是new了一個對象給多個thread所以不用static
package gay;
class text implements Runnable

public synchronized void run()

} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
s--;
System.out.println("還有"+s+"張票");

public class Dss {
public static void main(String[] args) {
text a=new text();
Thread aa=new Thread(a);
Thread bb=new Thread(a);
aa.start();
