How to Access Predefined Fonts, Sizes, and Colors in Java?
When creating a Java program, you may want to customize the appearance of text by accessing predefined fonts, sizes, and colors. This process can be accomplished using the GraphicsEnvironment class.
To obtain the list of available fonts, use the following code:
<code class="java">GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); String[] fonts = ge.getAvailableFontFamilyNames();</code>
Once you have the font names, you can create a drop-down list or other UI element to allow the user to select a font from the available options.
For example, you can create a JComboBox to choose fonts like this:
<code class="java">JComboBox fontChooser = new JComboBox(fonts);</code>
The Font class provides methods like getSize() and getStyle() to determine and modify the font size and style at run-time.
<code class="java">Font font = new Font(fontName, fontStyle, fontSize);</code>
Similarly, you can use the Color class to obtain and set the desired text color.
<code class="java">Color color = new Color(redValue, greenValue, blueValue);</code>
By using these techniques, you can dynamically adjust the appearance of text in your Java program, allowing users to customize the visual presentation.
