Method

StringgetMD5Sum(String file)
Returns the lowercase string representation of the file's MD5 sum. 
try {
    MessageDigest digest = MessageDigest.getInstance("MD5");
    InputStream is = new FileInputStream(file);
    byte[] buffer = new byte[8192];
    int read = 0;
    while ((read = is.read(buffer)) > 0) {
        digest.update(buffer, 0, read);
    is.close();
    byte[] md5sum = digest.digest();
    BigInteger bigInt = new BigInteger(1, md5sum);
    return bigInt.toString(16);
} catch (NoSuchAlgorithmException e) {
    return "";
