Java tends to be more prevalent in building the user interface for desktop or enterprise applications. Protecting user data from unauthorised access is an ongoing challenge that Java backend developers must face up. They use secure programming techniques, such as cryptographic algorithms offered by the Java Cryptography Extension (JCE) library, to encrypt sensitive data. Java’s versatility allows developers to use it to create custom server-side solutions for processing and managing data using popular application servers such as Apache Tomcat and Jetty. Servlet, JSP, and Struts are just a few ways Java facilitates web development. These tools help develop backend logic, process data, manage database connections, and handle HTTP requests and responses.

JPA (Java Persistence API) is a Java specification for accessing, persisting, and managing data between Java objects and a relational database. They are server-side Java programs that handle client requests and return a response. Java Developer job titles and responsibilities will vary depending on the employer. Some companies will expect candidates to only work in Java, while others expect Java Developers to also be proficient in other coding languages.

Featured in Architecture & Design

As many Java developers liaise with IT vendors, you will need good verbal and written communication skills.

• This means you will need to attend regular standups and meetings, help colleagues with problems, and help your team plan and manage your projects.
• Senior .NET developers carefully analyze software specifications and system requirements to ensure high-quality concept implementation using optimal operating procedures.
• Maven and Gradle are powerful build automation tools used in Java projects for managing dependencies, compiling source code, running tests, and packaging the code for deployment.
• Java is an Object-Oriented Programming (OOP) language, meaning it organizes design around objects (as opposed to functions and logic).
• But because its source code is initially turned into a binary byte code, Java can be considered a compiled and interpreted language.
