How to resize text in java

I have seen that in photoshop text can be easily resized just by dragging them. How can we do the same thing in Java? Any idea on how to resize text in java? Added a snapshot of letter "A" resized in photoshop

Please let me know what is wrong with this code?

public class ResizeImage extends JFrame {

    public ResizeImage(){
        JPanel panel = new JPanel(){
            public void paintComponent(Graphics g) {
                // In your paint(Graphics g) method
                // Create a buffered image for use as text layer
                BufferedImage textLayer = new BufferedImage(240, 240, 
                                              BufferedImage.TYPE_INT_RGB);

                // Get the graphics instance of the buffered image
            Graphics2D gBuffImg = textLayer.createGraphics();

                // Draw the string
                gBuffImg.drawString("Hello World", 10, 10);

                // Rescale the string the way you want it
                gBuffImg.scale(200, 50);

                // Draw the buffered image on the output's graphics object
                g.drawImage(textLayer, 0, 0, null);
                gBuffImg.dispose();
            }
        };
        add(panel);
    }

    public static void main(String [] args){
        ResizeImage frame = new ResizeImage();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        frame.setSize(300, 300);
        frame.setVisible(true);
    }
} 

One way is to use an AffineTransform (this variant also fades the color).

import java.awt.*;
import java.awt.geom.AffineTransform;
import java.awt.image.BufferedImage;
import javax.swing.*;
import java.io.File;
import javax.imageio.ImageIO;

public class StretchText {

    public static void main(String[] args) throws Exception {
        // used to stretch the graphics instance sideways
        AffineTransform stretch = new AffineTransform();
        int w = 640; // image width
        int h = 200; // image height
        int f = 21; // Font size in px
        String s = "The quick brown fox jumps over the lazy dog.";

        final BufferedImage bi = new BufferedImage(
                w,h,BufferedImage.TYPE_INT_RGB);
        Graphics2D g = bi.createGraphics();
        g.setFont(new Font("Serif",Font.PLAIN,f));
        g.setRenderingHint(
                RenderingHints.KEY_TEXT_ANTIALIASING, 
                RenderingHints.VALUE_TEXT_ANTIALIAS_ON);

        // paint BG
        g.setColor(Color.WHITE);
        g.fillRect(0, 0, w, h);
        g.setColor(Color.BLACK);

        for (int i=0; (i*f)+f<=h; i++) {
            g.drawString(s, 0, (i*f)+f);
            // stretch
            stretch.concatenate(
                    AffineTransform.getScaleInstance(1.18, 1d));
            g.setTransform(stretch);

            // fade
            Color c = g.getColor();
            g.setColor(new Color (
                    c.getRed(),
                    c.getGreen(),
                    c.getBlue(),
                    (int)(c.getAlpha()*.75)));
        }

        g.dispose();

        ImageIO.write(bi, "png", new File(
                new File(System.getProperty("user.home")), 
                "StretchText.png"));
        Runnable r = new Runnable() {
            @Override
            public void run() {
                JLabel gui = new JLabel(new ImageIcon(bi));
                JOptionPane.showMessageDialog(null, gui);
            }
        };
        SwingUtilities.invokeLater(r);
    }
}

You can use TextLayout to get the geometry, as shown here. The example scales the image to fill the frame. JInternalFrame might be a good choice to leverage the frame's resizing feature. Alternative, the example cited here shows how to click and drag multiple selections.

u can define type of font

e.g.

Font f = new Font("SansSerif", Font.BOLD, 40)
