System.arraycopy(elementData, index, elementData, index + 1, size - index); elementData[index] = element; size++; } 复制的部分越大,此操作就越慢。这使得添加元素的ArrayList操作效率相对较低。然而,到达应该完成插入的位置确实非常有效。 2.2LinkedList.add() LinkedList的实现允许我们相当容易...

Converts the elements in the current List<T> to another type, and returns a list containing the converted elements. CopyTo(Int32, T[], Int32, Int32) Copies a range of elements from the List<T> to a compatible one-dimensional array, starting at the specified index of the target array...

QList是Qt框架中的一个动态数组类,用于存储相同类型的元素。QList内部实现上采用了一种称为间接数组(indirect array)的数据结构,结合了链表和动态数组的特性。下面是对QList在查找、插入和删除操作上的性能分析: 查找操作: 对于QList来说,随机访问的时间复杂度为O(1),与QVector类似。这意味着,访问QList中的任意...
