**
## /1.龜兔race 規則: turtle兔同時起步, 終點爲100米, rabbit跑步的能力強(每10毫秒秒跑2米), 烏龜跑步的能力弱(每10毫秒秒跑1米) 途中: 1.兔子跑到10米的時候, 讓龜10毫秒, 接着跑 2.兔子跑到50米的時候, 讓龜100毫秒, 接着跑 3.兔子跑到80米的時候, 讓龜1000毫秒, 接着跑 提示: 其中烏龜繼承於Thread類, 兔子類實現Runnable接口/

主類中(調用兔子和烏龜類)
Thread turtle = new Turtle();
Rabbit rabbit = new Rabbit();
Thread thread = new Thread(rabbit);
turtle.start();
thread.start();
