How to Access and Use Predefined Fonts, Sizes, and Colors in Java?

Accessing Predefined Fonts, Sizes, and Colors in Java

Problem:
If you want to populate a JComboBox with a list of fonts, sizes, and colors, you need to find a way to obtain the predefined options available on the system.

Solution:
To access the predefined fonts in Windows, you can use GraphicsEnvironment.getAvailableFontFamilyNames():

<code class="java">GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fonts = ge.getAvailableFontFamilyNames();</code>

Customizing Font Attributes
Once you have the font names, you can set the font size and style at runtime. For example:

<code class="java">// Create a new font object with the specified attributes
Font font = new Font("Arial", Font.BOLD, 12);</code>

Populating the JComboBox
With the font names and attributes, you can populate the JComboBox:

<code class="java">// Populate the font JComboBox
for (String fontName : fonts) {
    jcbFonts.addItem(fontName);
}</code>

Font Chooser GUI Example
You can create a simple GUI to demonstrate the font selection:

<code class="java">// Create a FontCellRenderer for custom font display
FontCellRenderer renderer = new FontCellRenderer();

// Create the JComboBox with the fonts
JComboBox fontChooser = new JComboBox(fonts);
fontChooser.setRenderer(renderer);

// Display the font chooser dialog
JOptionPane.showMessageDialog(null, fontChooser);</code>

This example will display a dialog where you can select a font and view a preview of the selected font.
