Java 9 - 改进的JavaDocs( Improved JavaDocs)

可以使用javadoc工具生成Java文档。 它目前以html 4.0格式生成文档。 在java 9中，我们可以在命令行参数中使用-html5选项生成html 5格式的文档。

旧样式java文档

请考虑C:/ JAVA文件夹中的以下代码。

Tester.java

/**
  * @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");
   }
}

现在运行jdk 7的javadoc工具来生成文档。

C:\JAVA>javadoc -d C:/JAVA Tester.java
Loading source file tester.java...

它将在C:/ JAVA目录中创建java文档页面，您将看到以下输出。

支持搜索和HTML5的新Java文档

使用-html5标志运行jdk 9的javadoc工具以生成新类型的文档。

C:\JAVA> javadoc -d C:/JAVA -html5 Tester.java
