What is the meaning of @jls in javadoc?

Question

• @jls 4.3.2. Class object
• @jls 9.8 Functional Interfaces
• @jls 9.4.3 UI body
• @since 1.8 * /

Found this javadoc in some core Java classes, what does this mean? when to use javadoc in writing?

Answer 1

@jls points to the Java language specification section.

See for example:

• 4.3.2 Class Object
• 9.8 Functional Interfaces
• 9.4.3 Body of the interface method

The last annotation in your @since question @since used to indicate the version of Java ( 1.8 , which is Java 8), in which the document class or method was first available.
