Java 9改进的JavaDocs Java 9 REPL（JShell） Java 9创建多版本的jar Java文档可以使用javadoc工具生成。它目前以html 4.0格式生成文档。在java 9中，我们可以通过在命令行参数中使用- html5选项生成html 5格式的文档。 旧式的java文档 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...
