Java 11 Programming for Beginners 3.5: Documentation Using Javadoc

This video tutorial covers the use of comments in Java, focusing on Javadocs for external documentation. It explains the difference between normal comments and Javadocs, emphasizing the importance of documenting APIs for external users. The tutorial provides guidelines for writing effective Javadocs, including the placement of annotations and the documentation of parameters. It also demonstrates how to generate and view Javadocs using Gradle. The video concludes with a preview of the next section, which will cover handling input and errors using a Pig Latin converter example.

What is the primary purpose of Javadoc comments in Java?

• To format code consistently

• To document code for external users

• To provide internal notes for developers

• To highlight code errors

Why is it important to document the 'why' rather than the 'how' in Javadocs?

• Because the 'why' is easier to write

• Because the 'how' is self-explanatory

• Because the 'why' is more useful for understanding the purpose

• Because the 'how' is irrelevant

Where should Javadoc comments be placed in relation to annotations?

• After the annotation

• Before the annotation

• After the method

• At the end of the file

What should be documented in an API to ensure clarity?

• Only the class names

• Parameters and return values

• Only the method names

• Only the package names

Where can you find the generated Javadocs after running Gradle?

• In the source directory

• In the build directory under Docs

• In the main directory

• In the resources directory
