Guava features and specs

  • Comprehensive Collection Utilities
    Guava provides a wide range of collection utilities, including immutable collections and multimap implementations, enhancing Java's standard collections framework.
  • Functional Programming Features
    It offers functional programming features like predicates, functions, and suppliers, allowing developers to write cleaner and more concise code.
  • Enhanced String Manipulation
    Guava includes powerful string manipulation utilities, such as splitters, joiners, and utilities for dealing with string operations effectively.
  • Concurrency Utilities
    The library provides advanced concurrency utilities, such as ListenableFuture and various RateLimiter options, which aid in writing concurrent applications.
  • I/O Utilities
    Guava offers comprehensive I/O utilities, simplifying tasks like reading and writing data, and managing files and streams.
  • Optional and Other Core Libraries
    Guava introduces the Optional class and other core library features, which aid in dealing with null values and avoid usage of raw null references.

Possible disadvantages of Guava

  • Large Library Size
    Guava is a large library that can significantly increase the size of your project, which might be problematic for applications with strict size constraints.
  • Learning Curve
    Due to its comprehensive nature and wide range of functionalities, there can be a steep learning curve for new users unfamiliar with its tools.
  • Overhead of Unused Features
    Incorporating Guava can result in including many features that a particular project might not use, leading to unnecessary overhead.
  • Compatibility Issues
    There might be compatibility issues with certain Java versions or other libraries, especially if they also introduce similar functionalities.
  • Abandonment of Some Features
    Some features of Guava may become obsolete with newer Java versions as the language incorporates similar capabilities natively.

RxJava features and specs

  • Asynchronous Programming
    RxJava provides tools for composing asynchronous and event-based programs using observable sequences, making it easier to manage concurrent tasks.
  • Composability
    With RxJava, complex asynchronous workflows can be composed of simpler observable sequences, allowing for modular and reusable code.
  • Error Handling
    RxJava offers a wide range of operators and try-catch constructs to manage and respond to errors in a resilient manner.
  • Rich Operator Set
    RxJava comes with an extensive set of operators that can be used to filter, transform, and combine observable sequences for powerful data manipulation.
  • Backpressure Support
    The library provides the ability to handle backpressure, which helps manage situations where producers of data are faster than consumers.

Possible disadvantages of RxJava

  • Steep Learning Curve
    RxJava introduces a reactive programming paradigm that can be difficult for developers new to this approach to grasp immediately.
  • Complexity in Debugging
    The abstract nature of observables and operators can make it challenging to debug ReactiveX code compared to traditional imperative code.
  • Verbose Syntax
    Using RxJava often leads to more verbose code with chains of operators, which can decrease code readability if not well-documented.
  • Performance Overhead
    RxJava can introduce some performance overhead due to abstraction layers, which might not be suitable for all performance-critical applications.
  • Library Size
    For mobile applications, the size of the RxJava library can be a drawback if minimizing application size is a priority.

  • My First blog.
    The repo I researched for the first bit was was guava. Its a popular project that meets all of my requirements. "Guava is a set of core Java libraries from Google that includes new collection types (such as multimap and multiset), immutable collections, a graph library, and utilities for concurrency, I/O, hashing, primitives, strings, and more!

    As a racist against Java Regex, I can't help wanting to try it out without regex (using Guava and Mug, my all-in-one toolbox). - Source: dev.to / about 1 year ago
  • Lists: do you know the nature of yours? The strange story of a data container in Java
    The first problem is at the level of Type System, given that a situation more correct would allow us to distinguish through the Collection Type which abstraction we are operating with, species if definable as mutable or immutable. The JCF was born at a time when great care was taken to offer immediate operational data structures, and with attention to performance, but with less attention to constructs or uses... - Source: dev.to / over 1 year ago

  • Twitter makes some of its source code public
    I mean, I guess, technically? If you define it like that, then Microsoft has people working for them for free, as does Google, as does Apple, etc. It's not that weird, and you can try to twist it to be weird, but those of us in the software industry largely regard this as a good thing.
