The IDE's Auto Comment Tool enables you to determine if your source code's Javadoc comments are valid as well as edit or even create the comments when necessary. The source code entities that have Javadoc comments are listed in the left pane and the tags and comments themselves are displayed in the right pane.
You open the Auto Comment Tool by right-clicking the file you want to document in the Projects window or Source Editor and choosing Tools > Auto Comment from the contextual menu.
The filter toolbar enables you to control which classes and members are displayed in the Auto Comment tool. The following table describes the buttons on the toolbar.

If an entity has a missing or incorrect Javadoc comment, you can click a command button to edit the command. The following table lists the command buttons.
If an entity has a missing or incorrect Javadoc comment, you can click a command button to edit the command. The following list describes the command buttons.
public String myMethod(Object param1, Object param2){}and you click Auto Correct, the following tags are generated in the Tag pane of the Javadoc window and in the Source Editor:
@param param1 @param param2 @return
You can create or edit the text of a Javadoc comment in the Auto Comment Tool's Javadoc Comment Text pane. The first sentence of the comment should be a summary description of the declared entity. The text may include HTML elements (such as <B> and <I>) for formatting the description. Heading elements (such as <H1> and <H2>) are reserved for use by the Javadoc tool. You can use the command buttons at the bottom of the window to include the HTML elements <B>, <I>, <U>, <CODE>, and <PRE> and the Javadoc {@link} in the description. For example:
/** * Returns the Class of this <I>Object</I>. * Java has a runtime representation for * classes--a descriptor of type Class-- * which the method getClass() returns for * any Object. */
You do not need to type the characters /** and */ or the leading asterisks in the Javadoc Comment Text field. These characters are automatically included when the IDE adds the comment to the source code.
You can create or edit the tags of a Javadoc comment in the Tags pane of the Auto Comment Tool. A Javadoc tag starts with the character @ followed by a special keyword. Tags are case sensitive. A Javadoc tag enables you to automatically generate information for the API documentation. For example, @author name adds an author entry with the specified name to the generated documentation. A tag must appear at the beginning of a line (otherwise it is treated as normal text). By convention, tags with the same name are grouped together. The following comment includes four Javadoc tags:
/** * A class representing a screen window. * For example: * Window win = new Window(parent); * win.show(); * * @author Haley J. Ryan * @version 1.3 00/08/08 * @see java.awt.BaseWindow * @see java.awt.Button */
To add a Javadoc tag to your comment, click New, select a Javadoc tag or type a new tag, and click OK. The tag is added to the Tags pane. In the Description field, type the text of the tag. The text may include HTML elements (such as <B> and <I>) and the inline Javadoc tag {@link}.
