How to prepopulate save dialog box using JFileChooser?

I am making an application that applies a filter to a picture. It asks the user where to save the new file immediately after selecting a source file. Is it possible to prepopulate the save dialog box with the source file name + _filtername?

This example for Open Dialog

        JFileChooser fd = new JFileChooser();
        fd.showOpenDialog(this);
        if(fd.getSelectedFile()==null&&pro_pic_text.getText().toString().trim().equals(""))
        {
            JOptionPane.showMessageDialog(this,"Choose your Profile Picrure","Warning",JOptionPane.WARNING_MESSAGE);
        }
        else
        {
            fileName = fd.getSelectedFile().getAbsolutePath();
            File ff = new File(fileName);
            String ffname = ff.getName();
            int aa = ffname.indexOf(".");
            fftype = ffname.substring(aa+1);
            if(fftype.equals("png") || fftype.equals("PNG") || fftype.equals("JPEG") || fftype.equals("jpeg") || fftype.equals("JPG") || fftype.equals("jpg"))
            {
                if(ff.length()<=51300)
                {
                    pro_pic_text.setText(fileName);
                }
                else
                {
                    JOptionPane.showMessageDialog(this,"File size larger then 50kb not allowed","Warning",JOptionPane.WARNING_MESSAGE);
                    pro_pic_text.setText("");
                }
            }
            else
            {
                JOptionPane.showMessageDialog(this,"Choose JPEG, JPG or PNG File","Warning",JOptionPane.WARNING_MESSAGE);
                pro_pic_text.setText("");

Start by having a read through How to Use File Choosers.

You want to use JFileChooser#setSelectedFile
