1. Getting Font Information

Font font = new Font("Arial", Font.PLAIN, 12);
System.out.println("Font name: " + font.getName());
System.out.println("Font style: " + font.getStyle());
System.out.println("Font size: " + font.getSize());

2. Creating a Font with Attributes

Map<TextAttribute, ?> attrs = new HashMap<>();
attrs.put(TextAttribute.FAMILY, "Arial");
attrs.put(TextAttribute.SIZE, 12.0f);
attrs.put(TextAttribute.WEIGHT, TextAttribute.WEIGHT_BOLD);
Font font = new Font(attrs);

3. Getting Font Metrics

FontMetrics metrics = font.getFontMetrics();
System.out.println("Ascent: " + metrics.getAscent());
System.out.println("Descent: " + metrics.getDescent());
System.out.println("Leading: " + metrics.getLeading());

4. Calculating Text Width

String text = "Hello, world!";
FontMetrics metrics = font.getFontMetrics();
int width = metrics.stringWidth(text);

5. Drawing Text

Graphics2D g = new Graphics2D();
g.setFont(font);
g.drawString(text, 10, 20);

6. Using a TextLayout

TextLayout layout = new TextLayout(text, font, RenderingHints.KEY_ANTIALIASING);
layout.draw(g, 10, 20);

7. Creating a GlyphVector

GlyphVector glyphVector = font.createGlyphVector(fontRenderContext, text);

8. Getting Glyph Information

int numGlyphs = glyphVector.getNumGlyphs();
for (int i = 0; i < numGlyphs; i++) {
    Glyph glyph = glyphVector.getGlyph(i);
    System.out.println(glyph.getPixelBounds());
}

9. Shaping Text

FontRenderContext renderContext = new FontRenderContext(null, false, false);
TextAttribute attribute = TextAttribute.LIGATURES;
Map<TextAttribute, ?> attrs = new HashMap<>();
attrs.put(attribute, TextAttribute.LIGATURE_COMMON);
AffineTransform transform = new AffineTransform();
Font shapedFont = font.deriveFont(attrs).deriveFont(transform);
String shapedText = shapedFont.layoutGlyphVector(renderContext, glyphVector, 0, false, 0.0f).getGlyphPainter(0).getLayout().getText();

10. Measuring Text Width with Glyphs

float width = 0;
for (Glyph glyph : glyphVector.getGlyphs()) {
    width += glyph.getAdvance();
}

11. Transforming Text

AffineTransform transform = new AffineTransform();
transform.translate(10, 20);
transform.rotate(Math.toRadians(45));
TextLayout layout = new TextLayout(text, font, transform, RenderingHints.KEY_ANTIALIASING);

12. Wrapping Text

TextLayout layout = new TextLayout(text, font, RenderingHints.KEY_ANTIALIASING);
layout.setParagraphStyle(new ParagraphStyle(alignment, 12f));

13. Getting Font Family

String familyName = font.getFamily();

14. Getting Font Style

int style = font.getStyle();

15. Getting Font Size

float size = font.getSize();

16. Getting Font Metrics

FontMetrics metrics = g.getFontMetrics(font);

17. Getting Text Width

int width = metrics.stringWidth(text);

18. Getting Text Height

int height = metrics.getHeight();

19. Drawing Text

g.drawString(text, 10, 20);

20. Drawing Text with Antialiasing

g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

21. Creating a Font

Font font = new Font("Arial", Font.PLAIN, 12);

22. Creating a Font with Different Style

Font font = new Font("Arial", Font.BOLD, 12);

23. Creating a Font with Different Size

Font font = new Font("Arial", Font.PLAIN, 18);

24. Getting Available Fonts

String[] fontNames = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();

25. Checking if a Font is Available

boolean isAvailable = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames().contains("Arial");

26. Setting Font in a JLabel

JLabel label = new JLabel("Hello, world!");
label.setFont(new Font("Arial", Font.PLAIN, 12));

27. Setting Font in a JTextField

JTextField textField = new JTextField();
textField.setFont(new Font("Arial", Font.PLAIN, 12));

28. Setting Font in a JButton

JButton button = new JButton("Click me!");
button.setFont(new Font("Arial", Font.BOLD, 12));

29. Setting Font in a JPanel

JPanel panel = new JPanel();
panel.setFont(new Font("Arial", Font.PLAIN, 12));

30. Setting Font in a JFrame

JFrame frame = new JFrame();
frame.setFont(new Font("Arial", Font.PLAIN, 12));
