In -depth analysis of Jimmutable Collections framework in the Java class library

In -depth analysis of Jimmutable Collections framework in the Java class library Jimmutable Collections is a framework that provides persistent inseparable sets in the Java class library.Its design goal is to provide efficient, thread security, and strong fault tolerance. In the traditional Java, most of the collection is variable, which means that we can modify the content of the collection, but it will also bring some problems.When multiple threads modify one variable collection at the same time, the problem of data consistency may cause data consistency.In addition, the frequency of gathering modification can also lead to performance problems.In order to solve these problems, Jimmutable Collections provides the concept of unchanged collection, that is, once the collection is created, it cannot be modified again. Jimmutable Collections provides a variety of unsatisfactory collection, including lists, sets, mapping and orderly sets.The operation methods of these collection are similar to the variable sets in the Java standard library, but the new inseparable sets are returned, not to modify the original collection. Below are some example code using Jimmutable Collections framework: 1. Create an unchanged list: JImmutableList<Integer> list = JImmutalbeList.of(1, 2, 3); 2. Add element to the unchanged list: JImmutableList<Integer> newList = list.insert(4); 3. Delete the element in the list: JImmutableList<Integer> newList = list.delete(2); 4. Get the element in the list: int element = list.get(0); 5. Create an unchanged collection: JImmutableSet<String> set = JImmutableSet.of("apple", "banana", "orange"); 6. Add elements to uncharacteria: JImmutableSet<String> newSet = set.insert("grape"); Jimmutable Collections has good performance and thread security in a multi -threaded environment, because the unavailable features make the shared collection of reading operations unlocking.In addition, because the non -changing collection cannot be modified, it can support the functions such as rolling and snapshot. To sum up, Jimmutable Collections provides a powerful and easy -to -use way to deal with uncharacteristic sets. It has significant effects in large data and high concurrency environments.By using the characteristics of uncharacteria, we can improve the performance, reliability and maintenance of code.
