  <h3>
    e656.  
    Getting the Font Faces for a Font Family</h3>

To create a <code>Font</code> object to draw text, it is necessary to specify
the font face name. This example demonstrates how to retrieve all the
font face names from a font family name.  Unfortunately, the method is
somewhat inefficient since it involves creating one-point size
<code>Font</code> objects for every available font in the system.  The example
caches all the information by creating a hash table that maps a font
family name to an array of font face names.

<P> See also <a href="../java.awt.font/ListFontFam.html" class="eglink"><font size="-1"><b>e655</b> Listing All Available Font Families</font></a>.  Note: J2SE 1.4
only support True Type fonts.


<pre>
    Map fontFaceNames = new HashMap();
    
    // Get all available font faces names
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    Font[] fonts = ge.getAllFonts();
    
    // Process each font
    for (int i=0; i&lt;fonts.length; i++) {
        // Get font's family and face
        String familyName = fonts[i].getFamily();
        String faceName = fonts[i].getName();
    
        // Add font to table
        java.util.List list = (java.util.List)fontFaceNames.get(familyName);
        if (list == null) {
            list = new ArrayList();
            fontFaceNames.put(familyName, list);
    
        }
        list.add(faceName);
    }
    
    // Replace the face name lists with string arrays,
    // which are more compact and convenient to use
    for (Iterator it=fontFaceNames.keySet().iterator(); it.hasNext(); ) {
        String familyName = (String)it.next();
        java.util.List list = (java.util.List)fontFaceNames.get(familyName);
        fontFaceNames.put(familyName, list.toArray(new String[list.size()]));
    }
    
    
    // Use the table
    String[] faces = (String[])fontFaceNames.get(<font color="#0066ff"><i>"Verdana"</i></font>);
