Comparison analysis of Javaslang and Java 8 Stream

Comparison analysis of Javaslang and Java 8 Stream Overview: In the Java 8, the Stream API was introduced, which provided a more convenient and efficient way to process collection data.However, there are still some restrictions and deficiencies in some aspects of Java 8 Stream.In order to solve these problems and provide a more powerful programming model, the Javaslang library was developed. Javaslang Overview: Javaslang is a functional programming library, which aims to provide a set of functions and data types to help simplify the defects of functional programming in Java 8 and provide more functions and better performance.It introduces many new data types and operators to make functional programming simpler, intuitive and readable. The differences and advantages of Javaslang and Java 8 Stream: 1. Variable VS Unknown: Java 8 Stream can perform a series of operations on the collection, but they may change the state of the original collection, which may lead to some side effects.The data type of Javaslang is immutable, and each operation will return a new instance without changing the state of the original instance.This can better control and manage data and reduce side effects. 2. Functional programming support: Java 8 Stream is introduced to support functional programming, but it is not intuitive and simple.Javaslang provides more functional programming methods, such as Curry (Curry), Compose (combination), Memoize (memory), etc., which can better organize and reuse code. 3. Rich data type: The Java 8 Stream only supports a assembly line operation, which may not be flexible enough for certain complex data processing requirements.Javaslang provides more data types, such as Option, Tuple, Either (either), etc., which can better process data requirements for various scenarios. 4. Abnormal treatment: The Java 8 Stream processing is needed to use the Try-Catch block, which will cause code redundant and difficult to maintain.Javaslang provides better abnormal processing mechanisms, such as Try, Either, etc., which can easily handle abnormal conditions. Example code: Java 8 Stream example: List<String> stringList = Arrays.asList("Apple", "Banana", "Orange", "Grape"); // Use stream for filtering, sorting and printing operations stringList.stream() .filter(s -> s.startsWith("A")) .sorted() .forEach(System.out::println); Javaslang example: List<String> stringList = Arrays.asList("Apple", "Banana", "Orange", "Grape"); // Use javaslang to filter, sort and print operations Stream.ofAll(stringList) .filter(s -> s.startsWith("A")) .sorted() .forEach(System.out::println); It can be seen from the above example code that using Javaslang can operate the collection data more concisely, and at the same time, you can also obtain better performance and readability. Summarize: JavaSlang is a powerful functional programming library. By introducing a series of new data types and operators, it makes up for the shortcomings of Java 8 Stream in some aspects.It provides better unrealized support, richer functional programming methods, more flexible data types and more convenient abnormal processing mechanisms.When processing collection data, select Javaslang to provide a better development experience and effect.
