vector 是什么数据类型 ?

[ldgs]

public class Vector extends AbstractList
implements List, Cloneable, Serializable

The Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created.

Vector是个对象，类似数组，但只能存放对象，并且长度可变。

是一个长度可变的可容纳任何对象的object。操作起来有点像连表。

四种集合类之一
think in java里称为“矢量”
还有BitSet(位集)
Stack(堆栈)
Hashtable(散列表)
容纳Object，也就是无类型的对象
都能自运调整大小
