Java documentation can be generated using javadoc tool. It currently generates documentation in html 4.0 format. In java 9, we can generate documentation in html 5 format by using -html5 option in command pne arguments.
Old style java documentation
Consider the following code in C:/JAVA folder.
Tester.java
/**
* @author MahKumar
* @version 0.1
*/
pubpc class Tester {
/**
* Default method to be run to print
* <p>Hello world</p>
* @param args command pne arguments
*/
pubpc static void main(String []args) {
System.out.println("Hello World");
}
}
Now run the javadoc tool of jdk 7 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:JAVATester.html... Generating C:JAVApackage-frame.html... Generating C:JAVApackage-summary.html... Generating C:JAVApackage-tree.html... Generating C:JAVAconstant-values.html...

Generating C:JAVAallclasses-frame.html... Generating C:JAVAallclasses-noframe.html... Generating C:JAVAindex.html... Generating C:JAVAhelp-doc.html...
It will create the java documentation page in C:/JAVA directory and you will see the following output.
New java documentation with Search and HTML5 support
Run the javadoc tool of jdk 9 with -html5 flag to generate new type of documentation.
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...

It will create the updated java documentation page in D:/test directory and you will see the following output.
