this time we go on to look at the Java data structure vectors (vector) & Stack (stack). The first is the vector, vectors (vector) classes are very similar to the traditional array, but the size of the vector can be changed dynamically according to
Standard Library Vector type

Vector C ++, VectorVector container typeA vector container is a template class that can store any type of objects (but must be the same class object ). The vector object can efficiently add elements at runtime, and the elements in the vector are
On the Internet, I accidentally saw an article about the Common Data Structures in Java, which has been thoroughly analyzed.
:) Linear tables, linked lists, and hash tables are common data structures. During Java Development, JDK has provided a

VectorSimilar to the built-in array,It has a continuous memory and the starting address remains unchanged.Therefore, it supports random access, that is, the [] Operator. However, because its memory space is continuous, inserting and deleting in the
