In -depth research on the technical principles of the Excalibur Collections framework in the Java class library

Excalibur Collections is a framework in the Java class library, which provides a rich set of data structures and algorithms to optimize the performance and reliability of the Java collection.This article will study the technical principles of the Excalibur Collection framework and explain it through the Java code example. The core principles of Excalibur Collections are the data and operations of separation collection.It is stored in a continuous memory block and maintains a index table in memory at the same time to improve the access and modification efficiency of the set.Below is an example of using Excalibur Collections framework: First of all, we need to add the dependency item of Excalibur Collections.You can add the following code to the project construction file (such as Pom.xml or Build.gradle): <!-Maven dependency item-> <dependency> <groupId>org.excalibur-collections</groupId> <artifactId>excalibur-collections</artifactId> <version>1.0.0</version> </dependency> groovy // Gradle dependencies implementation 'org.excalibur-collections:excalibur-collections:1.0.0' Next, we create an example program using Excalibur Collections.Suppose we need to store a huge integer set and calculate the sum of all of the elements.We can use the `LongarrayList` class of Excalibur Collections. import org.excalibur.collections.LongArrayList; public class ExcaliburExample { public static void main(String[] args) { // Create a longarraylist object LongArrayList numbers = new LongArrayList(); // Add some data to the collection numbers.add(10); numbers.add(20); numbers.add(30); numbers.add(40); // Calculate the sum of all elements long sum = 0; for (int i = 0; i < numbers.size(); i++) { sum += numbers.get(i); } System.out.println ("Summary:" + Sum); } } In the above example, we first created an `LongarrayList` object, and then add some data to the set using the` adD` method.Next, we use the `Get` method to traverse the collection and seek all the sums of all the items. The advantage of Excalibur Collection is that it uses efficient internal data structure and index tables to improve the performance and reliability of sets.It can process a large amount of data and provide faster access and modification speed.In addition, EXCALIBUR Collections also provides other various data structures and algorithms, such as `IntarrayList`,` HashSet`, `Hashmap`, etc. to meet different needs. To sum up, the Excalibur Collections framework improves the performance and reliability of the Java collection by separating the data and operations of the collection, as well as the efficient internal data structure and index table.It is a powerful and easy -to -use library that can help developers handle large -scale data sets.
