There are 22 design patterns in java divided into three categories – creational, structural and behavioral design patterns. Check out the post to learn about these design patterns, their intent and how to implement them with an example. XML is widely used technology to store or transport data and it’s platform independent. Java provides various API’s to read, write or manipulate XML data.
Another important thing to know about Java EE 8 was the last release of Java EE from Oracle, and now, Oracle has moved Java EE to an open-source foundation (Eclipse Foundation), and it’s called Jakarta EE. In this article, I am going to share five excellent Java EE courses that cover both Java EE 7 and Java EE 8. If you are wondering what Java EE is and what Java EE 8 brings into the table, let me give you a brief overview of Java EE. Java EE has a structured application with clients, business, and enterprise layers. Java EE is an advanced specification to support Web Applications and Servlets. The Java EE specifications will now understand the minimum hardware requirements to install Java EE into our local system.
It is a set of specifications wrapping around Java SE (Standard Edition). The Java EE provides a platform for developers with enterprise features such Java EE Lessons as distributed computing and web services. Java EE applications are usually run on reference run times such as microservers or application servers.
A comprehensive post with 12 tutorials explaining different aspects of JDBC API, DataSource and JDBC integration with Spring Framework. Generics was introduced in Java 5 to remove type-casting in using Collection classes and to provide means for type checking at compile time. We can use Generics to create generic type interface and classes and we can use it with methods too. Learn about features of Generics in great detail in this extensive post. We use Collections almost in every application, this tutorial will explain Java Collections Framework in detail. Learn about collections framework interfaces, classes and algorithms in detail.
The EL represents a union of the
expression languages offered by JavaServer Faces technology and JSP technology. Every version of Java EE is a fully contained platform and doesn’t require learning or knowing anything about the previous versions. For starters I’d recommend free tutorials by Marty Hall, especially Configuring & Using Apache Tomcat to get you up and running. Based on Java EE version history there are technologies present in lower versions which are not available in the higher version. Or is it better to learn the latest version since their purpose of doing it is to improve the previous version. You’ll learn what JEE specifications and implementations are and how to use them and understand how the various Java EE APIs work together to make you a productive developer.
Learn how to use Apache Axis 2 to create SOAP based web services, complete tutorial with client program to test the web service. We don’t like exceptions but we always have to deal with them, great news is that Java Exception handling framework is very robust and easy to understand and use. Check out the post to learn about Exception Handling and best practices to follow for better exception handling. Learn about the Java annotations and the benefits of using annotations. The post explains java built-in annotations, how to create custom annotations, meta annotations and how we can parse annotations of a class using Reflection API. Java IO package contains classes to work with Files, Stream data and File System.
As per my personal experience, I learn most when I do a project and apply whatever theory and practical I have learned from the course, and that’s why I recommend this course. It’s also a CA-comprehensive course, with more than 18 hours of content. You will learn a lot of things like design patterns, best coding practices, and how to create maintainable, robust software.
