Resize a picture to fit a JLabel

Question

I\'m trying to make a picture fit a JLabel. I wish to reduce the picture dimensions to something more appropriate for my Swing JPanel.

I tried with setPreferredSiz

public void selectImageAndResize(){    
    int returnVal = jFileChooser.showOpenDialog(this); //open jfilechooser
    if (returnVal == jFileChooser.APPROVE_OPTION) {    //select image
        File file = jFileChooser.getSelectedFile();    //get the image
        BufferedImage bi;
        try {
            //
            //transforms selected file to buffer
            //
            bi=ImageIO.read(file);  
            ImageIcon iconimage = new ImageIcon(bi);

            //
            //get image dimensions
            //
            BufferedImage bi2 = new BufferedImage(iconimage.getIconWidth(), iconimage.getIconHeight(), BufferedImage.TYPE_INT_ARGB); 
            Graphics g = bi.createGraphics();
            iconimage.paintIcon(null, g, 0,0);
            g.dispose();

            //
            //resize image according to jlabel
            //
            BufferedImage resizedimage=resize(bi,jLabel2.getWidth(), jLabel2.getHeight()); 
            ImageIcon resizedicon=new ImageIcon(resizedimage);
            jLabel2.setIcon(resizedicon);
        } catch (Exception ex) {
            System.out.println("problem accessing file"+file.getAbsolutePath());
        }
    }
    else {
        System.out.println("File access cancelled by user.");
    }
}
