Introduction
The Font class states fonts, which are used to render text in a visible way.
Class declaration
Following is the declaration for java.awt.Font class:
public class Font extends Object implements Serializable
Field
Following are the fields for java.awt.geom.Arc2D class:
static int BOLD -- The bold style constant.
static int CENTER_BASELINE --The baseline used in ideographic scripts like Chinese, Japanese, and Korean when laying out text.
static String DIALOG --A String constant for the canonical family name of the logical font "Dialog".
static String DIALOG_INPUT --A String constant for the canonical family name of the logical font "DialogInput".

Font Example
Create the following java program using any editor of your choice in say D:/ > AWT > com > tutorialspoint > gui >
AWTGraphicsDemo.javapackage com.tutorialspoint.gui; import java.awt.*; import java.awt.event.*; import java.awt.geom.*; public class AWTGraphicsDemo extends Frame { public AWTGraphicsDemo(){ super("Java AWT Examples"); prepareGUI(); } public static void main(String[] args){ AWTGraphicsDemo awtGraphicsDemo = new AWTGraphicsDemo(); awtGraphicsDemo.setVisible(true); } private void prepareGUI(){ setSize(400,400); addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent windowEvent){ System.exit(0); } }); } @Override public void paint(Graphics g) { Graphics2D g2 = (Graphics2D)g; Font plainFont = new Font("Serif", Font.PLAIN, 24); g2.setFont(plainFont); g2.drawString("Welcome to TutorialsPoint", 50, 70); Font italicFont = new Font("Serif", Font.ITALIC, 24); g2.setFont(italicFont); g2.drawString("Welcome to TutorialsPoint", 50, 120); Font boldFont = new Font("Serif", Font.BOLD, 24); g2.setFont(boldFont); g2.drawString("Welcome to TutorialsPoint", 50, 170); Font boldItalicFont = new Font("Serif", Font.BOLD+Font.ITALIC, 24); g2.setFont(boldItalicFont); g2.drawString("Welcome to TutorialsPoint", 50, 220); } }
Compile the program using command prompt. Go to D:/ > AWT and type the following command.
D:\AWT>javac com\tutorialspoint\gui\AWTGraphicsDemo.java
If no error comes that means compilation is successful. Run the program using following command.
D:\AWT>java com.tutorialspoint.gui.AWTGraphicsDemo
