Are you familiar with Java but want to get the most out of your Java programs? In this course, Kathryn Hodge teaches the basics of object-oriented programming in Java, so you can write code that’s secure, scalable, and easier to troubleshoot. Kathryn begins by showing how object-oriented principles are embedded into the Java language from the first code file you create. She looks at how classes, instances, and constructors embody the idea of representing real-life objects in code. Kathryn not only shows how to apply object-oriented principles in your own programs, but also explains how Java leverages these principles behind the scenes. While many resources about object-oriented programming focus on abstract examples, the goal of this course is to get away from the abstract and focus more on practical examples of these principles in Java. Along with deep dives into the source code, this course also provides several challenges and solutions to help you apply what you’ve learned.

Learn how to work with the Java Persistence API (JPA), the standard for building Java enterprise applications that need to have persistent data.

Learn more advanced uses of the JPA, including inheritance mapping strategies, Java Persistence Query Language (JPQL), the Criteria API, and more.

Get a quick overview of the different flavors of Java—SE, EE, and ME—and find out which platform is right for your development workflow.

There is demand for engineers who know how to automate API testing. In this course, instructor Angie Jones covers how to use REST Assured to make various types of API requests in Java, with and without additional data, and how to verify the response received from the API. Angie explains why API testing is necessary and why automating API testing is an efficient and effective approach to keeping your APIs healthy. She introduces you to the REST Assured testing library. Angie discusses the anatomy of an API request, then shows you how to make GET, POST, PUT, and DELETE requests. She describes how you can serialize data to send as part of the request. Angie explains how you can validate API responses and deserialize data received from the response.

Maven makes Java programming easier! Learn how to use Maven for build automation, reporting, and document management.

Explore different data structures in the Java language, and discover how you can leverage them to make your software more efficient.

Describes how to read and manage data from relational databases such as MySQL and SQL Server using the Java Database Connectivity (JDBC) API in applications programmed with Java.

Learn about using generics in Java. Discover how to describe generics in Java and create your own generic classes, interfaces, and methods.

Find the best IDE (integrated development environment) for coding in Java with this extensive overview of the most popular IDEs: NetBeans, IntelliJ, BlueJ, Eclipse, and JDeveloper.

Explore recursion. Discover approaches to solving problems using this method and examine recursive processes such as finding the factorial of a number and the Fibonacci series.

Welcome to this hands-on course covering the benefits and limitations of using AWS to create serverless Java applications. In this course, instructor Terezija Semenski shows you how to set up the environment and IntelliJ IDE so that you can develop, deploy, and debug your code on AWS Lambda. Terezija gets you started by writing your first “hello world” serverless application and exposing it via REST API. Plus, she explains how to implement custom inputs and outputs of the Lambda function and best practices around logging, tracing and performance tuning. By the end of this course, you will know how to build efficient serverless Java applications.

Make your Java code error free. Learn how to integrate JUnit with popular tools and IDEs (Eclipse, NetBeans, IntelliJ, and Maven), and conduct unit testing for Java applications.

Unit testing is of crucial importance in developing stable applications. Java developers need to write unit tests, and JUnit is the main unit testing framework for Java. In this course, trainer and developer Maaike van Putten helps you learn to test your Java code effectively. Maaike explains what unit testing is and the advantages that it offers. She covers JUnit and shows you how to set it up and run your first test. Maaike steps through the process of writing a basic test, including useful tools like JUnit Annotations, JUnit Write, JUnit DisplayName, and more. She goes over more advanced uses of JUnit, such as dependency injection, parameterized tests, and timeouts, to name a few. Maaike finishes up with a quick peek at next steps you can take, like how to make code ready for unit testing, best practices, and a brief overview of Mockito.

Learn how to create and parse XML with a variety of Java APIs and libraries, including DOM, SAX, JAXB, and more.

Learn how to develop more dynamic, responsive applications with JavaFX. Explore the kinds of applications that JavaFX properties, JavaBeans, and bindings can help you construct.

Explore how to load dynamic content from JavaScript and jQuery using AJAX methods.

Explore how the JavaScript Object Notation (JSON) format works and how you can use it to read and share data in your web projects.

Want to put your JavaScript skills to the test? Welcome to JavaScript Code Challenges! Join instructor Emma Bostian as she serves up over a dozen JavaScript tasks and walks through the solutions for each. Emma frames each challenge using real-world examples, like setting up a ticking clock in a document, filtering vegetarian dinner options from a menu, and calculating the bill from a trip to a coffee shop. Each challenge is self-contained, so you can watch them in any order, and most solutions are less than two dozen lines of code, so you can quickly learn what you need and move on to the next lesson. Whether you want to learn new ways to use JavaScript or test your existing knowledge, this course can help you sharpen your skills.
