javadoc工具将你Java程序的源代码作为输入,输出一些包含你程序注释的HTML文件。
每一个类的信息将在独自的HTML文件里。javadoc也可以输出继承的树形结构和索引。
由于javadoc的实现不同,工作也可能不同,你需要检查你的Java开发系统的版本等细节,选择合适的Javadoc版本。
实例
下面是一个使用说明注释的简单实例。注意每一个注释都在它描述的项目的前面。
在经过javadoc处理之后,SquareNum类的注释将在SquareNum.html中找到。
import java.io.*; /** * This class demonstrates documentation comments. * @author Ayan Amhed * @version 1.2 */ public class SquareNum { /** * This method returns the square of num. * This is a multiline description. You can use * as many lines as you like. * @param num The value to be squared. * @return num squared. */ public double square(double num) { return num * num; } /** * This method inputs a number from the user. * @return The value input as a double. * @exception IOException On input error. * @see IOException */ public double getNumber() throws IOException { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader inData = new BufferedReader(isr); String str; str = inData.readLine(); return (new Double(str)).doubleValue(); } /** * This method demonstrates square(). * @param args Unused. * @return Nothing. * @exception IOException On input error. * @see IOException */ public static void main(String args[]) throws IOException { SquareNum ob = new SquareNum(); double val; System.out.println("Enter value to be squared: "); val = ob.getNumber(); val = ob.square(val); System.out.println("Squared value is " + val); } } 如下,使用javadoc工具处理SquareNum.java文件: $ javadoc SquareNum.java Loading source file SquareNum.java...
