public synchronized int size() { return elementCount; } 容器是不是为空: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 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...
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...

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. ...
