Guava is a Java open source framework developed by Google, which provides a wide range of tools to help programmers develop high-quality Java code. Guava encapsulates a large number of common Java libraries, making the code more concise and readable. The framework contains many functional and efficient data structures, including immutable sets, caching utilities, expiration monitoring utilities and synchronization primitives.
Guava is a widely used open source framework because of its rich functions, readable code and convenient maintenance. The data structure and utilities provided by Guava can also reduce the difficulty of coding and enable developers to concentrate on realizing their core business functions. Guava is one of the tools that every Java developer must master.
What does guava mean? -What's unique about it?
A unique feature of guava is its unchangeable setting. These collections are thread-safe and can be shared and reused without changing their state. Guava toolset also has tools for caching and expiration time monitoring. They help programmers avoid repeating expensive calculations.
The efficient synchronization primitive provided by Guava has a lock-free design, which makes it possible to achieve optimized concurrency performance when accessing data in a multithreaded environment. Guava also provides Unicode processing, which makes it easier for developers to manipulate and process Unicode strings.
In a word, Guava is an indispensable tool in Java development, which makes Java code more concise, readable and easy to maintain. Its unique characteristics enable it to play an important role in writing efficient and high-quality Java code.
What does guava mean? -In what fields are they widely used?
Guava has been widely used in the field of Java development, both in various server-side applications and in Android mobile applications, giving full play to its advantages. Guava's collection types and utilities are also widely used in big data and distributed computing systems.
Guava's singleton and caching utility symbolize that it is widely used in some high concurrency scenarios. Guava is also widely used in the test, because it can easily simulate various scenarios, such as data loading and operation up to 10GB, without causing system crash during the test.
Generally speaking, Guava is a universal open source framework, which is used by programmers in various fields, including Java application and mobile application development, big data processing and testing utilities.
