Analysis of GNU TROVE framework technology in the new generation of Java library

Analysis of GNU TROVE framework technology in the new generation of Java library Abstract: The data structure and algorithm in the Java class library are usually abstract design to adapt to various use scenarios, which makes them not efficient in performance in some specific scenarios.To solve this problem, the GNU TROVE framework came into being.This article will analyze the GNU TROVE framework and provide the corresponding Java code example. 1 Introduction GNU TROVE is a high -performance, ultra -fast open source Java class library, which is used to provide optimized original types.It focuses on providing data structures that provide efficient, low memory occupation to replace the general set framework in the Java standard library.GNU TROVE's set framework supports original types, such as int, byte, float, etc., as well as arrays about these types.It greatly improves performance by reducing the cost of loading and boxing. 2. Common questions When using the set framework in the Java standard library, due to the generic mechanism of Java, the original type must be transformed by boxing and boxing.This will lead to additional memory overhead and performance loss.Therefore, when processing a large amount of original type data, using the Java standard library is not the best choice. 3. The advantage of GNU TROVE GNU TROVE solves the performance problem of the Java standard library by providing optimized original types.Its main advantages include: (1) Avoid packing and boxing: By directly operating the original type data, the performance loss of boxing and boxing is avoided; (2) Low memory occupation: GNU Trave uses a more compact data structure to reduce memory occupation; (3) High performance: Due to the avoidance of boxing and boxing, and low memory occupation, GNU TROVE is faster than the Java standard library when processing a large amount of original type data. 4. Examples of GNU TROVE Here are some examples of Java code using the GNU TROVE framework: (1) Use Tinthashset to store the set of INT type: TIntHashSet set = new TIntHashSet(); set.add(1); set.add(2); set.add(3); System.out.println(set.contains(2)); System.out.println(set.size()); (2) Use TintinthashMap to store the key value of INT type: TIntIntHashMap map = new TIntIntHashMap(); map.put(1, 100); map.put(2, 200); map.put(3, 300); System.out.println(map.get(2)); System.out.println(map.size()); (3) Use TintarrayList to store INT type: TIntArrayList list = new TIntArrayList(); list.add(1); list.add(2); list.add(3); System.out.println(list.get(1)); System.out.println(list.size()); 5 Conclusion The GNU TROVE framework is a high -performance Java class library for optimizing the processing of the original type collection.It avoids boxing and boxing and reducing memory occupation to improve performance.When processing a large number of original type data, using GNU TROVE can significantly improve efficiency.It is strongly recommended that developers use the GNU TROVE framework when they need to process the original type data.
