Vector(int size)第三种构造方法创建指定大小的向量,并且增量用 incr 指定。增量表示向量每次增加的元素数目。 Vector(int size,int incr)第四种构造方法创建一个包含集合 c 元素的向量: Vector(Collection c)除了从父类继承的方法外 Vector 还定义了以下方法: 序号 方法描述 1 void add(int index, Object ...
public static void main(String[] args) { // initial size is 3, increment is 2 Vector v = new Vector(3, 2); System.out.println("Initial size: " + v.size()); System.out.println("Initial capacity: " + v.capacity()); v.addElement(new Integer(1)); v.addElement(new Integer(2)...
Thus, the size in bits of of a vector is determined by appealing to its vector shape. Some Java platforms give special support to only one shape, while others support several. A typical platform is not likely to support all the shapes described by this API. For this reason, most vector...

public synchronized int size() { return elementCount; } 容器是不是为空: 代码语言:javascript 复制 public synchronized boolean isEmpty() { return elementCount == 0; } 返回枚举类型的元素迭代器,这是一个有意思的方法,相当于用枚举包装了当前的元素,Enumeration是一个接口,这个接口有两个方法,一个是...

2)Resize:Both ArrayList and Vector can grow and shrink dynamically to maintain the optimal use of storage, however the way they resized is different. ArrayList grow by half of its size when resized while Vector doubles the size of itself by default when grows. ...
