Notice the use of HTML metacharacters and tags in this doc comment The Javadoc utility translates doc comments into HTML, and arbitrary HTML elements contained in doc comments end up in the resulting HTML document Occasionally programmers go so far as to embed HTML tables in their doc comments, although this is uncommon The most commonly used tags are <p> to separate paragraphs; <code> and <tt>, which are used for code fragments; and <pre>, which is used for longer code fragments The <code> and <tt> tags are largely equivalent The <code> tag is more commonly used and, according to the HTML 401 specification, is generally preferable because <tt> is a font style element (The use of font style elements is iscouraged in favor of style sheets [HTML401]) That said, some programmers prefer <tt> because it is shorter and less intrusive Don't forget that escape sequences are required to generate HTML metacharacters, such as the less than sign (<), the greater than sign (>), and the ampersand (&) To generate a less than sign, use the escape sequence < To generate a greater than sign, use the escape sequence > To generate an ampersand, use the escape sequence & The use of escape sequences is demonstrated in the @throws tag of the above doc comment Finally, notice the use of word this in the doc comment By convention, the word this always refers to the object on which the method is invoked when it is used in the doc comment for an instance method The first sentence of each doc comment becomes the summary description of the element to which the comment pertains The summary description must stand on its own to describe the functionality of the entity it summarizes To avoid confusion, no two members or constructors in a class or interface should have the same summary description Pay particular attention to overloadings, for which it is often natural to use the same first sentence in a prose description Be careful not to include a period within the first sentence of a doc comment If you do, it will prematurely terminate the summary description For example, a documentation comment that began with A college degree, such as BS, MS, or PhD would result in a summary description of A college degree, such as B The best way avoid this problem is to avoid the use of abbreviations and decimal fractions in summary descriptions It is, however, possible to include a period in a summary description by replacing the period with its numeric encoding, .

Afont is an instance of the Font class, which includes a font family, a size, and a font style And, as you might expect, a font family is an instance of the FontFamily class, which is a group of typefaces that differ only in style A typeface is a named collection of drawing strokes that make up the outlines of the characters, such as those you're reading right now It's the typeface name that you're used to seeing in the " Font" menu of most programs The font style constitutes the ariations within a typeface, such as bold, italics, and underline So a typeface would be "Arial," a font family would include "Arial Regular" and "Arial Bold," and a font would be "12-point Arial Bold" Fonts can be measured in several sizes, including pixels, points, ems, and design units A pixel is a point of light on a screen or a point of ink on a printer Pixels are often packed into inches for measurement For example, the resolution of video display adapters and printers is typically specified in dots per inch (dpi), where a dot is the same as a pixel Pixels are devicedependent, so a pixel on a 72-dpi display bears no size relationship to a pixel on a 300-dpi printer A point, on the other hand, is 1/72nd of an inch no matter what device it's drawn on, and the Graphics object will scale appropriately as text is drawn Converting between points and pixels requires knowing the dpi of the device you're drawing on, which is conveniently available via the GraphicsDpiY property:[1].
