Question

Is there a way to convert a String (in hex format) into a Integer? I know of Integer.parseInt(string, 16), but it does not handle the 0x prefix. I’m looking something to the effect of Integer.decode(string) from standard Java.

Thanks in advance.

Answer 1

int convert(String s) {
    int base = 10;
    if (s.toLowerCase().startsWith("0x")) {
        base = 16;
        s = s.substring(2);
    }
    return Integer.parseInt(s, base);
}
