The collection includes arraylist, vector. hashmap, linklist, treemap, and hashset.To avoid implementation differences, Java provides a collection interface, which specifies that some public methods must be implemented.For example, Add. Remove and size. No matter how the underlying layer is implemented, I know that they have at

Arraylist and vector use arrays to store data. The number of elements in the array is greater than that in the actual storage to add and insert elements. Both allow direct serial number index elements, however, data insertion is designed to move array elements and other memory operations. Therefore, index data is inserted slowly. Because vector uses the Synchronized Method (thread-safe), its performance is inferior to that of arraylist, the sort

The List
The advantage of generics: it increases the efficiency and flexibility for compiling Object-oriented Programs in c # language. It does not forcibly pack or unbox the value type, or forcibly convert the reference type downward, so the performance is improved.

Collection Interface
Collection is the most basic collection interface. A collection represents a group of objects, namely, elements of the collection ). Some collections allow the same elements while others do not. Some can be sorted, while others cannot. The Java SDK does not provide classes that directly inherit from collect
In STL, the basic containers include string, vector, list, deque, set, and map.
Set and map are unordered storage elements. They can only be accessed through the interfaces provided by it.
Set: Set, used to determine whether an element is in a group and is rarely used.Map: ing, which is equivalent to a dictionary. It maps a value to another value. If you want to create a dictionary, use it.

Study finished STL series BIS, Oneself wrote a program practicing! The program uses the architecture of the second series of articles. Study of one of the STL and the second, for the basic principles of STL have a fundamental understanding. In fact, about these kinds of containers, have been contacted before, but in Java, when learning is also swallowed! Now feel that is really learning taboo, or step for good. Speed can be slowed down a little, that should be solid!

STL containers can be divided into the following categories:I. Sequence containers, including vector, list, deque, string.
2. Associated containers: set, multiset, map, mulmap, hash_set, hash_map, hash_multiset, and hash_multimap

performance defects cannot be remedied. The "Fat interface" of the container that BJ thinks is not a problem. If there is a good convention, it means that if a method returns a container abstracted to the collection, in fact, we will make the minimum functional assumption for this container, that is, we should not make too many requirements on the order, operati

I'll briefly describe the followingFirst of all, SPRINGMVC and spring are bo

Also, adding an element may sometimes require allocating additional storage space, in which case each element must be moved to a new storage space.
