In this J2EE online test, we’ve added twenty important questions to cover the basic concept of the J2EE platform, APIs, and its services.
J2EE is a cross-platform technology, built on top of the Java SE platform. It gives you a runtime environment for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications.
J2EE platform comprises the list of services, APIs, and protocols that enable the development of multi-tiered, Web-based applications.
It is a set of specifications that encompasses enterprise technologies like JMS, WS, Servlets, JSP, and EJB. Most of these specifications are implemented using Java.
You can refer to more about the J2EE from the wiki. Next, we recommend you not just leave from here but instead attempt some more cool quizzes and tutorials on Java/Python/Selenium and related programming articles from our blog. Now, click to start the J2EE online test.
