怎么给Vector里面的元素排序   有现成的方法吗?

------解决方案--------------------
static void sort(List list)
Sorts the specified list into ascending order, according to the natural ordering of its elements.
static void sort(List list, Comparator c)
Sorts the specified list according to the order induced by the specified comparator.
------解决方案--------------------
自己写个比较器，建议lz不要使用冒泡法。冒泡法的时间复杂度太大。

因为
public class Vector extends AbstractList
implements List, RandomAccess, Cloneable, java.io.Serializable

具体代码参考一下
//: c11:DirList.java
// Displays directory listing.
