各位，我有两个问题：
1｀在跑完之后，tower2里面依然是空的，也就是说调用方程move后，tower2没有被改变，我想知道问题出在哪了。
2｀两个方程moveTopTo和move为什么必须是static？
在此先谢谢了！

import java.util.Stack; public class ThreePFive { public static void main String[] args { int n = 3; Stack<Integer> tower0 = new Stack<Integer>; Stack<Integer> tower1 = new Stack<Integer>; Stack<Integer> tower2 = new Stack<Integer>; for int i = n - 1; i >= 0; i-- { tower0.pushi; } moven, tower0, tower1, tower2; } public static void moveTopToStack<Integer> ori, Stack<Integer> des { int top = ori.pop; des.pushtop; } public static void moveint n, Stack<Integer> ori, Stack<Integer> des, Stack<Integer> buf { if n > 0 { moven - 1, ori, buf, des; moveTopToori, des; moven - 1, buf, des, ori; } }
}
