Frameworks and libraries for every programming language are essential to understanding and mastering it. We’ve compiled a list of the top 5 Java libraries that every developer should be familiar with.
Businesses, companies, students, and developers alike are aware of the pervasiveness of IT and its various subfields, including programming and software development, maybe more so than at any other time. Some of the highest-paid occupations include software engineers and IT specialists. It is also a job that is constantly changing, necessitating ongoing education. Similarly, Java development is one of the most sought-after professions in today’s market. The adaptability of the language itself can be credited with this achievement. Web, mobile, and video game applications employ Java, a potent general-purpose language.
The advantages of using libraries — eliminating repetition and saving time — are generally known to all developers. Frameworks and libraries for every programming language are essential to understanding and mastering it. We’ve compiled a list of the top 5 Java libraries that every developer should be familiar with for those wishing to learn and advance their skills.
1. Java Standard Libraries
The best course of action is always to start with the frameworks and libraries offered by the programming language. For development tools, the same is true. Despite having some of the most reliable and practical libraries, the Java standard libraries are frequently disregarded. Among them are:
- Java.util
- Java.lang
- Java.math
- Java.net
- Java.io /Java.nio
Students and fresh Java developers may efficiently learn various third-party libraries using the Java Standard Library to provide a firm foundation upon which to build.
2. JUnit
Java programmers may design test cases and execute unit tests using JUnit, another framework for unit testing. Understanding unit testing tools are essential since they are essential for repairing bugs. Every time a developer runs a test, JUnit generates fresh examples of the test class. Because JUnit performs tests randomly and without adhering to a predetermined order, it is crucial to create test cases independent of one another.
3. Mockito
Mockito is an open-source mocking framework, as you could guess from the name. Unit testing proficiency is frequently demanded of Java developers. Mockito aids programmers in creating tests using a clear and straightforward API. Developers may use it to test fake or duplicate objects for test- and behaviour-driven behaviour. The top Java mocking framework, according to StackOverflow, is Mockito.
4. Google Guava
Google Guava is a free, open-source Java library replacement for Apache Commons. Guava extends Java with more cutting-edge features and capabilities, including brand-new generic classes for bitmaps, multisets, strings, I/O, caches, graph libraries, etc. One of the most widely used Java libraries has always been Guava.
5. HttpClient
Over the network, HTTP resources are requested and retrieved using the HttpClient tool. Java HttpClient supports HTTP/1.1 and HTTP/2. Both synchronous and asynchronous programming paradigms are supported. HttpClient is created using a builder and, once set, is fixed. It allows the Java developer to submit several queries and get resources and configuration data for each.
