Move file without using renameTo()

In my Java program, I would like to display the progress of moving a file. I use the following snippet of code to copy files, which allows me to track the bytes copied and shows it in a progress bar. I was wondering if the code code be adapted to move files rather than just copy them?

        BufferedInputStream bis = new BufferedInputStream(new FileInputStream(sourceFile));
        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(targetFile));


            int theByte;

            while((theByte = bis.read()) != -1)
            {
                bos.write(theByte);

            }

            bis.close();
            bos.close();

Okay, so a "move" operation is a copy with a "delete" at the end, for example...

BufferedInputStream bis = null;
BufferedOutputStream bos = null;

try {
    bis = new BufferedInputStream(new FileInputStream(sourceFile));
    bos = new BufferedOutputStream(new FileOutputStream(targetFile));

    int theByte;

    while((theByte = bis.read()) != -1)
    {
        bos.write(theByte);
    }

    bos.close();
    bis.close();
    // You may want to verify that the file's are the same (ie the file size for example)
    if (!sourceFile.delete()) {
        throw new IOException("Failed to remove source file " + sourceFile);
    }

} catch (IOException exp) {
    exp.printStackTrace();
} finally {
    try {
        bis.close();
    } catch (Exception exp) {
    }
    try {
        bos.close();
    } catch (Exception exp) {
    }
}
