Java 9 Improved Javadoc

Java 9 New Features

The javadoc tool can generate Java documentation, Java 9 The output of javadoc now conforms to HTML compatibility5 Standard.

Java 9 Previous old documentation

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");
　　　}
}

Using jdk 7 The javadoc generated documentation:

Executing the above command will generate in C:/Generating the document page under the JAVA command, as shown in the figure below:

Java 9 The generated documentation is compatible with HTML5 Standard
