Java Notes

Font

Description

The java.awt.Font class is used to create Font objects to set the font for drawing text, labels, text fields, buttons, etc.

Generic Font Names

There are three logical/generic font names. Java will select a font in the system that matches the general characteristics of the logical font.

serifThis text is in a serif font. Often used for blocks of text (eg, Times).
sansserifThis text is in a SansSerif font. Often used for titles (eg, Arial or Helvetica).
monospacedThis text is in a Monospaced font, often used for computer text (eg, Courier).

You can also get a list of the system fonts on the host computer. See below.

Constructor

Font f = new Font(name, style, size);

String nameint styleint size
"serif"
"sansserif"
"monospaced"

or a system font.
Font.PLAIN
Font.BOLD
Font.ITALIC
Font.BOLD+Font.ITALIC
Integer point size -- typically in range 10-48.

Example

JButton b = new JButton("OK");
b.setFont(new Font("sansserif", Font.BOLD, 32));

Available system fonts

For maximum portability, use the generic font names, but you can use any font installed in the system. It is suggested to use a font family name, and create the font from that, but you can also use the fonts directly. You can get an array of all available font family names or all fonts.

// Font info is obtained from the current graphics environment.
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();

//--- Get an array of font names (smaller than the number of fonts)
String[] fontNames = ge.getAvailableFontFamilyNames();

//--- Get an array of fonts.  It's preferable to use the names above.
Font[] allFonts = ge.getAllFonts();

Using Fonts for Graphics

Font f;
f = new Font(String name, int style, int size);	// creates a new font

name is "Serif", "SansSerif", or "Monospaced", or a font on the system. style is Font.PLAIN. Font.BOLD, Font.ITALIC, or Font.BOLD+Font.ITALIC. size is the point size, typically in the range 8-48.

Example

Font big = new Font("SansSerif", Font.Bold, 48);
. . .
g.setFont(big);
g.drawString("Greetings Earthling");

Unicode fonts

If you're running a recent version of Windows, you probably already have a Unicode font installed, Arial Unicode MS, which is a very extensive Unicode font. If you're not running windows, you can get a the Bitstream Cyberbit font, which is quite complete (about 30,000 characters), but lacks a few of the the lesser used characters (eg, Old Cyrillic).

Windows installation instructions:

  1. Download from ftp://ftp.netscape.com/pub/communicator/extras/fonts/windows/Cyberbit.ZIP [6.3MB Zipped]. It's also available other places on the Internet. It was originally written by Bitstream, but they no longer offer it for free download.
  2. Unzip into a temporary directory.
  3. Start the Fonts control panel, and add Bitstream Cyberbit font from that directory.
