Java API 文档生成器
以下程序使用文档注释中的一些重要标签。你可以根据你的需要使用其他标签。
关于 AddNum 类的文档将生成 HTML 文件 AddNum.html,但同时,还将创建一个名为 index.html 的主文件。
import java.io.*; /** * <h1>Add Two Numbers!</h1> * The AddNum program implements an application that * simply adds two given integer numbers and Prints * the output on the screen. * <p> * <b>Note:</b> Giving proper comments in your program makes it more * user friendly and it is assumed as a high quality code. * </p> * @author Zara Ali * @version 1.0 * @since 2014-03-31 */ public class AddNum { /** * This method is used to add two integers. This is * a the simplest form of a class method, just to * show the usage of various javadoc Tags. * @param numA This is the first paramter to addNum method * @param numB This is the second parameter to addNum method * @return int This returns sum of numA and numB. */ public int addNum(int numA, int numB) { return numA + numB; } /** * This is the main method which makes use of addNum method. * @param args Unused. * @return Nothing. * @exception IOException On input error. * @see IOException */ public static void main(String args[]) throws IOException { AddNum obj = new AddNum(); int sum = obj.addNum(10, 20); System.out.println("Sum of 10 and 20 is :" + sum); } }
现在,使用 Javadoc 实用程序处理上述 AddNum.java 文件,如下所示 −
$ javadoc AddNum.java Loading source file AddNum.java... Constructing Javadoc information... Standard Doclet version 1.7.0_51 Building tree for all the packages and classes...
