Making a BufferedImage to add textfield content to it

Question

Hi guys,
I'm stuck on this problem where I'm trying to create an image to become a bufferedImage so that I can add textfield content to it. At my best approach, I have got the bottom code to be to the best of my knowledge:
if (stack.size() >= 0 ) // keeps drawing to the limit of 10 (set in MainStack)
                   File f = new File("p1.jpg");
                       BufferedImage i = ImageIO.read(f);
                       Graphics g = i.getGraphics();
                       g.drawString(textFieldString, 10, 10);
                   ImageIO.write(i, "jpg", f);
                   g.dispose();
                 //textFieldString1 = textFieldString1 + 1;
                     JLabel content = new JLabel("No. "+Counter+" in stack = "+ textFieldString);
                     content.setIcon(new ImageIcon(getClass().getResource("p1.jpg")));
                     Counter = Counter + 1 ;
                     //pic1.append(textFieldString);
                     // pic1.setIcon(new ImageIcon(getClass().getResource("p1.jpg")));
                    //pic1.drawString(""+textFieldString);
                      Insets insets = displayPanel.getInsets();
                      Dimension size = content.getPreferredSize();
                      content.setBounds(40 + insets.left, stackLayer + insets.top,
                      size.width, size.height);
                      //pic1.setBounds(40 + insets.left, stackLayer + insets.top,
                      //size.width, size.height);
                      displayPanel.setLayout(null);
                      displayPanel.add(content);
                      displayPanel.revalidate();
                      stackLayer = stackLayer - 30;
                  }Which gives me the following errors:
C:\Documents and Settings\Sukhdeep\My Documents\Dissertation\ProjectFiles\Demonstration.java:236: cannot find symbol
symbol  : variable ImageIO
location: class Demonstration
                       BufferedImage i = ImageIO.read(f);
                                                     ^
C:\Documents and Settings\Sukhdeep\My Documents\Dissertation\ProjectFiles\Demonstration.java:240: cannot find symbol
symbol  : variable ImageIO
location: class Demonstration
                   ImageIO.write(i, "jpg", f);
                   ^
2 errors
Tool completed with exit code 1Any help to correct these errors please? I think its something to do with
File f = new File("p1.jpg");But I'm not too sure...

Answer 1

This
test.java:10: cannot find symbol
symbol  : variable ImageIO
location: class Test
        BufferedImage i = ImageIO.read(f);means java cannot find the ImageIO class. You can import it with:
import javax.imageio.ImageIO;
