这篇教程Java 9 改进 Javadoc写得很实用，希望能帮到您。
javadoc 工具可以生成 Java 文档， Java 9 的 javadoc 的输出现在符合兼容 HTML5 标准。 Java 9 之前的旧版本文档 考虑以下文件代码 C:/JAVA/Tester.java: 实例 @author @version public class Tester { @param public static void main(String []args) { System.out.println("Hello World"); }} 使用 jdk 7 的 javadoc 生成文档： C:/JAVA>javadoc -d C:/JAVA Tester.javaLoading source file tester.java...Constructing Javadoc information...Standard Doclet version 1.7.0_21Building 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... 执行以上命令会再 C:/JAVA 命令下生成文档页面，如下图所示： 
Java 9 生成的文档兼容 HTML5 标准 使用 jdk 9 javadoc 命令中的 -html5 参数可以让生成的文档支持 HTML5 标准： C:/JAVA> javadoc -d C:/JAVA -html5 Tester.javaLoading source file Tester.java...Constructing Javadoc information...Standard Doclet version 9.0.1Building 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-frame.html...Generating C:/JAVA/allclasses-noframe.html...Generating C:/JAVA/allclasses-noframe.html...Generating C:/JAVA/index.html...Generating C:/JAVA/help-doc.html... 执行以上命令会再 C:/JAVA 命令下生成文档页面，如下图所示：
