When developing graphical user interfaces (GUIs) in Java using the Abstract Window Toolkit (AWT), you may need to manipulate the appearance of text and use different fonts for better visual presentation. In this blog post, we will explore how to work with fonts and perform basic text formatting within AWT components.

Working with Fonts
In Java AWT, fonts are represented by the Font class. You can create a Font object by specifying the font name, style, and size. The font name can be a platform-specific name or a logical name like “Arial” or “Times New Roman”. The style can be one of Font.PLAIN, Font.BOLD, Font.ITALIC, or a combination of them.
Here’s an example of creating a font object:
Font font = new Font("Arial", Font.BOLD | Font.ITALIC, 20);
To set the font of a component, such as a label or a button, you can use the setFont() method and pass in the Font object:
label.setFont(font);
button.setFont(font);
Performing Text Formatting
Java AWT provides several methods for performing basic text formatting, such as aligning the text, changing its color, and underlining it.
To align the text within a component, you can use the setAlignment() method and provide one of the constants from the TextAlignment class, like TextAlignment.LEFT, TextAlignment.CENTER, or TextAlignment.RIGHT:
label.setAlignment(TextAlignment.CENTER);
To change the color of the text, you can use the setForeground() method and pass in a Color object:
label.setForeground(Color.RED);
To underline the text, you can use the setFont() method and pass in a Font object created with the Font’s underline style flag:
Font font = new Font("Arial", Font.PLAIN | Font.UNDERLINE, 16);
label.setFont(font);
Conclusion
In this blog post, we explored how to work with fonts and perform basic text formatting in Java AWT. We learned how to create a Font object with a specific font name, style, and size, and how to apply it to AWT components. We also saw how to align text, change its color, and underline it.
By utilizing these font and text formatting techniques, you can enhance the visual appearance of your Java AWT GUI applications.
