Java 9 Javadoc Improvements
Java 9 New FeaturesThe javadoc tool can generate Java documentation. In Java 9, the output of javadoc now conforms to the compatible HTML5 standard.
Documentation from older versions before Java 9
Consider the following file code C:/JAVA/Tester.java:
Example
/**
* @author MahKumar
* @version 0.1
*/
public class Tester {
/**
* Default method to be run to print
* <p>Hello world</p>
* @param args command line arguments
*/
public static void main(String []args) {
System.out.println("Hello World");
}
}
Use JDK 7's javadoc to generate documentation:
C:\JAVA>javadoc -d C:/JAVA Tester.java Loading source file tester.java... Constructing Javadoc information... Standard Doclet version 1.7.0_21 Building tree for all the packages and classes... Generating C:\JAVA\Tester.html... Generating C:\JAVA\package-frame.html... Generating C:\JAVA\package-summary.html... Generating C:\JAVA\package-tree.html... Generating C:\JAVA\constant-values.html... Building index for all the packages and classes... Generating C:\JAVA\overview-tree.html... Generating C:\JAVA\index-all.html... Generating C:\JAVA\deprecated-list.html... Building index for all classes... Generating C:\JAVA\allclasses-frame.html... Generating C:\JAVA\allclasses-noframe.html... Generating C:\JAVA\index.html... Generating C:\JAVA\help-doc.html...
Executing the above command will generate a documentation page in C:/JAVA, as shown in the figure below:
Documentation generated by Java 9 is compatible with the HTML5 standard
Using the JDK 9 javadoc command's-html5parameter can make the generated documentation support the HTML5 standard:
C:\JAVA> javadoc -d C:/JAVA -html5 Tester.java Loading source file Tester.java... Constructing Javadoc information... Standard Doclet version 9.0.1 Building tree for all the packages and classes... Generating C:\JAVA\Tester.html... Generating C:\JAVA\package-frame.html... Generating C:\JAVA\package-summary.html... Generating C:\JAVA\package-tree.html... Generating C:\JAVA\constant-values.html... Building index for all the packages and classes... Generating C:\JAVA\overview-tree.html... Generating C:\JAVA\index-all.html...

Generating C:\JAVA\allclasses-noframe.html... Generating C:\JAVA\allclasses-noframe.html... Generating C:\JAVA\index.html... Generating C:\JAVA\help-doc.html...
Executing the above command will generate a documentation page in C:/JAVA, as shown in the figure below:
