sorted arraylist

Because of its functionality and flexibility, ArrayList is one of the most common collection classes used in the Java collection framework. ArrayList is a List implementation that uses a dynamic array to store elements, so that ArrayList can

1. ArrayList is a dynamic array-based data structure. The ArrayList is based on the linked list data structure.2. for Random Access to get and set, the ArrayList is better than the sorted list, because the ArrayList can be randomly located, and the

ArrayList and HashMap are asynchronous, while Vector and HashTable are synchronous. Therefore, Vector and HashTable are thread-safe, while ArrayList and HashMap are not thread-safe. Because synchronization takes machine time, the execution

We generally know the differences between arraylist and rule list:1. arraylist is a dynamic array-based data structure. The arraylist is based on the linked list data structure.2. for Random Access to get and set, arraylist thinks it is better than

Arraylist and hashmap are asynchronous, while vector and hashtable are synchronous. Therefore, vector and hashtable are thread-safe, while arraylist and hashmap are not thread-safe. Because synchronization takes machine time, the execution

What is the difference between ArrayList, list, and Vector ., Arraylistparts list The ArrayList, inclulist, and Vestor classes all implement the java. util. List interface, but they have different features, mainly as follows:I.

1.ArrayList is a data structure based on dynamic array, LinkedList based on the data structure of the linked list.2. For random access get and set,arraylist is better than LinkedList, because ArrayList can be randomly positioned, and linkedlist to

ArrayList and Vector use arrays to store data. The number of elements in the array is greater than that in the actual storage for adding and inserting elements. Both allow direct serial number index elements. However, inserting data must be designed

Considerations for using the set: 1,Objects can only be referenced in a set, and Native data types cannot be placed., We need to use native data type packaging classes to add them to the Set (jdk5 will automatically perform the packing and unpacking

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
