Using Annotations in Java (Java SE 11 Developer Certification 1Z0-819)
Annotations in Java help you make your code readable and help the compiler generate metadata for your Java types. This course will teach you how to use built-in annotations, develop custom Java annotations, and apply them to real-world applications.
What you'll learn
Do redundant XML-configurations get you down? Do you need annotations on your code to prevent run-time bugs and readability? In this course, Using Annotations in Java (Java SE 11 Developer Certification 1Z0-819), you’ll learn to apply built-in Java annotations to your Java 11 applications and create custom annotations to aid your business requirements when working with Java type system and annotations. First, you’ll explore the need for annotations in Java system and the annotations provided by the Java SE 11 SDK. Next, you’ll discover how to create custom annotations using Java 11 SDK and how to apply them to your Java 11 programs. Finally, you’ll learn how to annotate your Java annotations, improving the metadata for your Java types (classes, their fields and methods). When you’re finished with this course, you’ll have the skills and knowledge of annotations in Java 11 SDK needed to make your code more readable, easier to configure, and less prone to bugs on runtime.
