How to implement .psd to .jpg conversion using ImageMagick for a batch of files using Java

Question

I need to view .psd images in swing so I decided to convert that into .jpg and try to show it.

 My terminal command for single .psd to .jpg

 convert image.psd image.jpg (this is creating three images image-0.jpg,image-1.jpg,image-2.jpg)

but if I used

 convert image.psd[0] image.jpg (this gives me correct output)

But i need to convert .psd images using java. i tried this but it is not working

if (new File(_imageicon[i].toString()).getName().endsWith(".psd") || 
        new File(_imageicon[i].toString()).getName().endsWith(".PSD")) {
    File psdFile = new File(_imageicon[i].toString());
    if(psdFile.exists()) {
        System.out.println("_imageicon[i].toString()"+_imageicon[i].toString());               
        System.out.println("_imageicon[i].toString().replace"+_imageicon[i].toString().replace(".psd", ".jpg").replace(".PSD", ".jpg"));
        ProcessBuilder pb = new ProcessBuilder("convert", _imageicon[i].toString() , _imageicon[i].toString().replace(".psd", ".jpg").replace(".PSD", ".jpg"));
        pb.redirectErrorStream(true);
        try {
            Process p = pb.start();
        } catch (IOException ex) {
            Logger.getLogger(GridEditor.class.getName()).log(Level.SEVERE, null, ex);
        }

        ImageIcon ii = new ImageIcon(_imageicon[i].toString().replace(".psd", ".jpg").replace(".PSD", ".jpg"));
        Image imagepdf1 = ii.getImage();
        Image newimg = imagepdf1.getScaledInstance(100, 60, java.awt.Image.SCALE_SMOOTH);
        ii = new ImageIcon(newimg);
        _lbl[i].setIcon(ii);
    }
}

Any idea please suggest.

For batch convert use this

    ProcessBuilder pb = new ProcessBuilder("mogrify", "-format ", "jpg ", psdafterconvpath, psdpath + "\\" + "*.psd");
    pb.redirectErrorStream(true);
    try {
        Process p = pb.start();
    } catch (IOException ex) {
        Logger.getLogger(DefineTask.class.getName()).log(Level.SEVERE, null, ex);
    }
    }
