合法IP

Posted 2020-12-14 dongma

校验比较简单，只要在0-255之间就算合法

private static boolean ipValid(String ip) {
    String[] split = ip.split("\.");
    int len = split.length;
    if(len != 4){
        return false;
    }
    for (String s : split) {
        int i = Integer.parseInt(s);
        if(i <= 0 || i >= 255){
            return false;
        }
    }
    return true;
}
