Java Vector 类 Java 数据结构Vector 类实现了一个动态数组。和 ArrayList 很相似,但是两者是不同的:Vector 是同步访问的。 Vector 包含了许多传统的方法,这些方法不属于集合框架。Vector 主要用在事先不知道数组的大小,或者只是需要一个可以改变大小的数组的情况。
private void ensureCapacityHelper(int minCapacity) { // overflow-conscious code if (minCapacity - elementData.length > 0) grow(minCapacity); } // 扩容,传入的是需要最小的容量 private void grow(int minCapacity) { // overflow-conscious code // 以前的容量 int oldCapacity = elementData.length; ...
Returns a hash code value for the object. (Inherited from Object) IndexOf(Object, Int32) Returns the index of the first occurrence of the specified element in this vector, searching forwards from index, or returns -1 if the element is not found. IndexOf(Object) To be added (Inherite...

section Conclusion Java Vector API is a new feature for vectorized programming in Java, accelerating parallel computing through SIMD instruction set. It simplifies parallel code writing and enhances program performance and readability.
Do not use this class as a std::vector replacement in your code! 但是还是就兴冲冲地开始在自己的代码里面使用 ImVector 代替std::vector(好孩子不要在家里模仿),并且直接把对象存进去(而不是指针)。 然后我发现我其实需要引用语义的容器,因为我偶尔需要取出容器里面的值,在外部改变并塞回去;同一个对象放在...

@rnamdos Did you resolve this error in the python version of the function? I have had this error appear in a project I'm working on too. rnamdos commented Jul 15, 2021 @DuncanM-XR it was a noob mistake I made because I was still learning python. The code is fine, make sure you...

Java 集合:(八) Vector 子类 Stack 一、Stack 概述 1、Stack 是栈结构,它继承与 Vector。它的特性是:先进后出(FILO,First In Last Out)或 后进先出(LIFO,Last In First Out); 2、Stack是Vector的子类,比Vector多了几个方法,它的后进先出的特征,就是通过调用这几个方法实现的。
