 return parseInt(serial.replace(/-/g, ''), 16)
}
keygen("C6AD-0E40")

3333230144

and this java code 

private int keygens(String serial) {

        String s=serial.replaceAll("[-]", "");
     int dec=Integer.parseUnsignedInt(s,16);
                 return dec+dec+dec; //one dec give negative value wondering why !!
}
        System.out.print(keygens("C6AD-0E40"));

    `3_333_230_144` is bigger than `2_147_483_647` which is the largest possible `int` in java. Use `Long.parseUnsignedLong(String, int)` instead. – azurefrog Dec 20 '19 at 19:06
