Java Tools are software programs that facilitate the whole Java development, testing, and deployment process for developers. These instruments aid programmers in tracking, enhancing, troubleshooting, and bettering the performance of Java programs. Moreover, it enables you to examine the database, memory, and concurrency of Java applications and assists you in identifying runtime and compile-time problems. This article discusses 15 technologies that are considered best training software for Java developers to be familiar with by 2023 to stay updated. If you are already familiar with some of these Java tools, ignore them; otherwise, learn them.
Spring Boot 3.0
By allowing developers to focus only on the business logic and less on the boilerplate code, Spring Boot significantly decreases the amount of boilerplate code and increases developer productivity. Spring Boot 3.0, which was released in November 2022, is the most recent version. For Spring Boot 3.0, JDK 17 is necessary. JDK 8 no longer receives support. You can upgrade your project to Spring Boot 3.0 if you haven’t done so before. Be cautious, though, since there may be many deprecated libraries.
Git
Git is a version management tool. Being extensively used, it is an open-source system. When you wish to collaborate on a project with other team members, you can utilize Git. It keeps track of who uploaded the source code when and how it changed. The project can be managed by the user quickly and effectively. Java developers as well as other developers must use the Java tool, Git. Every programmer has to be familiar with git and how to utilize it. The optimum moment is 2023 if you didn’t learn in 2022.
Docker
An open-source platform called Docker is used to create and deliver programs in the form of containers. It makes use of Docker images, deployable artifacts that include your application and all of its dependencies and may be deployed. Generally, you could run into some problems. Running effectively on our local PC but failing to run on the target machine because of a problem with the program version, configuration settings, a missing file, etc. Nevertheless, if Docker is incorporated into your system, the same software may operate without any problems on other computers. In 2023, if you don’t know about Docker, you should. Docker is now used by every Java application to automate deployment.
Maven
Maven is a Java project management tool used mostly for managing dependencies. The build process will be quicker than ANT if Maven is used in the project. Its foundation is the POM (Project Object Model).
The POM file is an XML document that includes details about the project, the dependencies you utilized, and Maven configuration data for constructing the project.
AWS
The cloud service provider Amazon Web Services (AWS) is by Amazon. They provide their clients with 170+ different services. Database administration, application deployment, data storage, source control, communications, authentication, and other tasks may all be handled by Amazon. Deploying a Java web application on Amazon has many benefits, including affordability, dependability, security, scalability, and high performance. You may utilize Amazon S3 for storage needs. Nevertheless, you may utilize Amazon SNS for message services. Amazon Cognito is a service that you may use for authentication. The Java program can incorporate each of these services. To integrate Amazon with Java, AWS offers a variety of libraries.
Hibernate
An open-source Java framework called Hibernate is used to communicate between Java objects and databases. It is a lightweight ORM (Object Relational Mapping) tool. The Java classes that include database tables and Java data types can be mapped by Hibernate to the matching SQL data types. It’s because by defining the entity class, the Hibernate framework can automatically generate the table. The query doesn’t have to be manually written. We can easily get several tables since it makes it easier to write join queries.
JUnit
Testing a unit, section, or line of code that is a component of the entire software is known as unit testing. To speed up the execution of test cases, it needs to be a brief block of code. Integrated testing helps developers work more efficiently and saves them time by reducing defects following successful test case execution.
With successful unit testing, the developer gains confidence. Unit testing may be split into two categories. Manual testing is one, while automation testing is the other. Testing that is performed manually without the use of a tool is referred to as manual testing. Testing cases with Java tool support is referred to as automated testing.
A Java unit testing framework called JUnit is available for free. Java programmers use it to create and execute test cases. Many interfaces and classes are provided for JUnit via the JUnit package. JUnit makes it easy to build code, which cuts down on time. The JUnit 4.x framework uses annotations, which may be utilized for creating test cases. These are some annotations.
@Test
@Test(timeout=1000)
@BeforeClass
@Before
@After
@AfterClass
Try automated testing, which uses JUnit, if you are currently using manual testing. To ensure your productivity in the upcoming year, we can establish a goal to implement JUnit.
NoSql
Data is stored and retrieved using a NoSQL database. When massive volumes of data need to be saved, it is utilized. As NoSQL databases are non-relational databases, they don’t store data in tabular databases. It is a high-performance, document-based database that is simple to use. With NoSql, the schema is dynamic.
MongoDB, Redis, Neo4J, BigTable, and other types of NoSQL databases are examples.
Complex queries should not be run on NoSQL databases. Consider utilizing SQL if your queries are sophisticated.
Kubernetes
An open-source platform for automating the deployment, operation, and management of containerized applications, Kubernetes is often referred to as K8S. It is compatible with Docker and without it. Google released Kubernetes in 2014.
Java Kafka
Apache As Kafka is a distributed event streaming platform, it can handle and analyze limitless real-time data. Although it was created by LinkedIn, the Apache Software Foundation Team currently owns it. Scala and Java were used to create Kafka. It functions much like RabbitMQ. Big data processing is a good fit for Kafka.
Selenium
A free automated testing framework is Selenium. Users may test using several web browsers, including Chrome, Firefox, Safari, and Opera, by utilizing Selenium. It can only test online apps; it cannot test desktop or mobile ones. For handling test cases, Selenium and Junit may be integrated. It’s a test at the functional level. Languages like Java, C#, PHP, Python, and others are supported by Selenium. With Java and C#, its web drivers are now well-liked.
Conclusion
It will be even more worthwhile to hunt for employment as a Java developer in 2023 given the language’s broad use in fields like online and mobile application development as well as cutting-edge technologies like big data, the Internet of Things, blockchain, and artificial intelligence (AI).
