The most popular programming language for creating business applications in Java. One of the preferred programming languages is this. Java’s vast and feature-rich core library is one of its distinguishing qualities. Even though the Standard Java Library is strong, professional programme development requires additional Java libraries. Are you here to know the Top Libraries every Java Developer should know? FITA Academy offers the best Java Training In Chennai; we provide real-time training sessions with live projects.
Apache Commons extends several Java core libraries and is like the Swiss Army Knife of Java software development. There is a good possibility that the established and potent Apache Commons library already exists if you ever consider building a utility class for your project.
You are likely creating the wheel if you are working on a large project without utilising any Apache Commons libraries.
Processing diverse structured data is a requirement of software development. You must convert data between multiple formats, load data in different formats, or both. The standard data exchange format in contemporary software development is JSON. CSV, BSON, Protobuf, Avro, XML, YAML, and CBR are further common data formats.
Jackson is a collection of Java data processing libraries. A useful streaming JSON parser and generator library is Jackson JSON. It supports many more data types, like Guava, Jota, PC Collections, Avro, BSON, CBOR, CSV, Smile, Protobuf, XML, and YAML.
As stated before, XML is another popular data format that offers stringent data validation, storage, and transfer. The Java Standard Library now supports data binding and XML as of Java 8. FITA Academy provides Java courses with live projects and career guidance. The practical sessions with hands-on projects will be much useful in growing your technical skills at Java Online Course.
To work with XML in Java, JAXB offers all the necessary tools. It offers a reliable and effective method of converting Java code to XML. Annotation-based data binding is also included.
The process of developing software includes unit and integration testing. A single class (SUT) is frequently what you wish to test, but it depends on other complex classes or outside actions (such database operations or I/O activities). In such circumstances, mock testing is one technique to write unit/integration tests. By simulating the actions of other external service requests, you may concentrate solely on the class you’re testing.
The most popular mocking library in Java is called Mockito. You can use Mockito everywhere, whether you’re testing a tiny project or a big, complicated business Java project. It keeps your unit and integration tests tidy and offers a very straightforward, clear API.
AssertJ is the second TDD-related library. Verifying that the test result matches the anticipated result is one of the testing process’ key considerations. Two conventional test validation techniques are offered. Those two techniques are insufficient for an expert developer.
As software engineers, we must deal with data stores on a daily basis. There are numerous types of data stores available today, including SQL and numerous NoSQL data stores. A low-level API can be used to interact with the data store (eg, JDBC for SQL). As a result, introducing an abstraction layer between your application and the data store is the best way to handle the data store.
