Change Color and Font of text

This section illustrates you how to change color and font of text using TextAttributes class. A string is defined and the class AttributedString holds the string.

The TextAttribute.FONT defines the font to render text and the TextAttribute.FOREGROUND sets the color. The values defined, indicates the position of the element.

Here is the code of ShowColorAndFont.java

import java.awt.*;
import java.text.*;
import javax.swing.*;
import java.awt.font.*;

public class ShowColorAndFont extends JPanel {
  public void paint(Graphics g) {
  Graphics2D g2d = (Graphics2D) g;
  String text = "Java is an Object Oriented Programming Language.";
  Dimension dimension = getSize();

  Font font1 = new Font("Book Antiqua", Font.PLAIN, 30);
  Font font2 = new Font("Monotype Corsiva", Font.PLAIN, 30);

  AttributedString attributedString = new AttributedString(text);
  attributedString.addAttribute(TextAttribute.FONT, font1);
  attributedString.addAttribute(TextAttribute.FONT, font2, 1, 4);
  attributedString.addAttribute(TextAttribute.FONT, font2, 6, 7);
  attributedString.addAttribute(TextAttribute.FONT, font2, 9, 10);
  attributedString.addAttribute(TextAttribute.FONT, font2, 12, 17);
  attributedString.addAttribute(TextAttribute.FONT, font2, 19, 26);
  attributedString.addAttribute(TextAttribute.FONT, font2, 28, 38);
  attributedString.addAttribute(TextAttribute.FONT, font2, 40, 47);

  attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red, 0, 1);
  attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red, 5, 6);
  attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red, 8, 9);
  attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red, 11, 12);
  attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red, 18, 19);
  attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red, 27, 28);
  attributedString.addAttribute(TextAttribute.FOREGROUND, Color.red, 39, 40);

  g2d.drawString(attributedString.getIterator(), 40, 80);
  }
  public static void main(String[] args) {
  JFrame frame = new JFrame("Show Color and Font");
  frame.getContentPane().add(new ShowColorAndFont());
  frame.setSize(700, 200);
  frame.show();

  }
