Let us see some third-party library developers in Java that can be used by the application of useful tasks. For using these libraries, Java developer must be aware of it and this is the main thing this blog explains.
1) Logging libraries
In every project, there is a need for logging libraries and they are quite common. They are quite significant from the server-side application as the logs are kept where it is visible for you to see what is actually present in your application. Although JDK shifts with its own library which is logging there are lots of better alternatives that are actually available eg: SLF4j, Log4j, and LogBack.
2) JSON parsing libraries
In the current world of web services and internet of things (IoT), JSON has become the go-to protocol for carrying information from client to server. The XML has been changed as the most wanted way for transferring information in a platform-independent way. There is no JSON library present in a JDK and yet luckily there are lots of good third-party libraries which permits you to both create and parse JSON messages.
3) Unit testing libraries
The single most significant thing is unit testing which isolates and average developer from a good developer. For not writing unit tests, programmers often are given excuses but the most common excuse for ignoring unit testing is the experience and knowledge that is to be left for famous unit testing library eg: PowerMock, Junit, and Mockito.
4) General Purpose Libraries
If you are a Java developer you will definitely have a good time with very good general purpose and a third-party library in a Java developer eg: Apache Commons and Google Guava. In my projects, these libraries are present and they reduce lots of tasks.
5) Http Libraries
The lack of support for HTTP is the only thing which is not apt for JDK. With the help of using classes in java.net package, it is not quite simple and seamless by using open source, third-party libraries similar to HttpCore and Apache HttpClient.
The assistance of HTTP 2.0 is brought by the JDK9 and better assistance for HTTP with famous HTTP client libraries eg: HttpCore and HttpClient.
6) XML parsing libraries
You can find lots of XML parsing libraries that are present eg: JAXB, Xerces, JAXP, Dom4j, Xstream etc. Xerces2 is the future generation of high performance and fully compliant XML parsers. The Xerces Native Interface (XNI) is unveiled by the latest version of Xerces and a complete framework for constructing parser components and configurations that is quite modular and simple to program.
7) Excel reading libraries
With the Microsoft Office, the real world application has to interact and you need to trust it or not in some form or the other. There are lots of application requirements for offering functionality to export data in Excel and if you are willing to do the same from your Java application by requiring Apache POI API.
8) Bytecode Libraries
For generating the code or interacting with bytecodes if you are writing framework or libraries then there is a need for bytecode library. They permit you to read and change the bytecode produced by an application. In Java, there are famous bytecode libraries like javassist and Cglib Nodep.
9) Database connection pool libraries
From Java application, if you are interacting with the database but not using database connection pool libraries then you are not having something. It takes time to create connections during runtime and make the request processing slower and it advises the DB connection library usage.
10) Messaging libraries
Messaging is the same as logging and database connection which is the common feature for most of the real-world Java application. JMS is offered by Java, but that has no portion linked to JDK and you need to have ideal jsm.jar.
