l1-016 查验身份证java

好的，针对您的问题，我可以提供以下Java代码来实现身份证号码的校验：

public static boolean isIDNumberValid(String idNumber) {
    if (idNumber == null || idNumber.length() != 18) {
        return false;
    }
    char[] chars = idNumber.toCharArray();
    int[] ints = new int[chars.length];
    for (int i = 0; i < chars.length; i++) {
        ints[i] = Integer.parseInt(chars[i] + "");    }
    int[] weights = new int[]{7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2};
    int sum = 0;
    for (int i = 0; i < weights.length; i++) {
        sum += ints[i] * weights[i];
    }
    int mod = sum % 11;
    String[] checkCodes = new String[]{"1", "0", "X", "9", "8", "7", "6", "5", "4", "3", "2"};
    String checkCode = checkCodes[mod];
    return checkCode.equals(chars[17] + "");
}
