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：
