不用循环，显示1~100算法

public class demo {

 public static void main(String[] args) {
        final int len = 100;
        final Timer timer = new Timer();
        timer.schedule(
                new TimerTask() {
            private int i = 1;
            public void run() {
                System.out.println(i++);
                if (i > len) {
                    this.cancel();
                    timer.cancel();
                }
            }
        }, new Date(), 1);
    }

}
