Java9 - JavaDocs增强

可以使用javadoc工具生成Java文档。当前，它以html 4.0格式生成文档。在Java 9中，无涯教程可以通过在命令行参数中使用-html5选项来生成html 5格式的文档。

旧样式Java文档

考虑以下C:/JAVA文件夹中的代码。

/**
  * @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工具生成文档。
