In -depth interpretation of the technical principles of the Solong Collections framework in the Java class library

Solong Collections framework is a powerful collection framework in the Java class library, which provides developers with efficient, easy -to -use and flexible collection processing function.This article will deeply interpret the technical principles of the Solong Collections framework in the Java library and provide the necessary Java code examples. 1. Overview of SOLONG COLLECTIONS framework Solong Collections framework consists of a series of data structures and algorithms, which aims to optimize the performance and memory occupation in Java.It provides an efficient way to operate collection data, and allows developers to choose the most suitable data structure according to actual needs. Second, the technical principles of the SOLONG COLLECTIONS framework 1. Collection based on the native array: Solong Collections framework will store collection data in the native array to increase the access speed and reduce memory overhead.By directly operating the array elements, the expenses of the object packaging and disassembly are avoided. 2. Memory Management: Solong Collections framework uses a special memory management technology, called Off-Heap memory allocation.Off-Heap memory allocation stores the object in the pile of memory, reduces the occupation of Java pile memory, and reduces the pressure of GC (garbage recovery).This can avoid the performance problems caused by frequent memory allocation and release in the conventional Java set framework. 3. Automatic expansion: The set in the Solong Collections framework will automatically expand when required to accommodate more elements.It uses a dynamic array data structure. When the array elements are insufficient, it will automatically expand operation.This automatic expansion mechanism makes the collection process more flexible without manual management capacity. 4. Parallel security: Solong Collections framework provides a collection of thread security, which can be used in a multi -threaded environment.It is based on the lock-free algorithm to handle concurrent access to avoid the performance loss caused by the lock competition.This makes the collection operation in the multi -threaded environment more efficient and reliable. Third application example of the Solong Collections framework Here are some code examples of some Solong Collections frameworks: 1. Create an ArrayList collection: import io.github.sosongsong.collections.lists.*; List<Integer> list = new ArrayList<>(); list.add(1); list.add(2); list.add(3); System.out.println (list); // Output: [1, 2, 3] 2. Create a HashSet collection: import io.github.sosongsong.collections.sets.*; Set<String> set = new HashSet<>(); set.add("apple"); set.add("banana"); set.add("orange"); System.out.println (set); // Output: [Apple, Banana, Orange] 3. Create a ConcurrenThashMap collection: import io.github.sosongsong.collections.maps.*; Map<String, Integer> map = new ConcurrentHashMap<>(); map.put("one", 1); map.put("two", 2); map.put("three", 3); System.out.println (Map.get ("Two"); // Output: 2 It can be seen through the above examples that the Solong Collections framework provides a similar API as the Java standard library, which is very convenient to use.While providing high -performance and flexible collection processing capabilities, it also guarantees the advantages of thread safety and memory management. Summarize: The technical principles of Solong Collections framework in the Java library mainly include the collection of native array, off-heap memory allocation, automatic capacity expansion, and concurrency.Through these technical means, the Solong Collections framework implements efficient, reliable and easy -to -use collection processing functions.Whether in a single -threaded or multi -threaded environment, it can provide excellent performance and stability. It is an indispensable weapon for Java developers.
