代碼如下：

package cn.gov.csrc.util;/*** 18 位身份證驗證器* * @author admin* */ public class IDCard {final int[] wi = { 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, 1 };final int[] vi = { 1, 0, 'X', 9, 8, 7, 6, 5, 4, 3, 2 };private int[] ai = new int[18];public IDCard() {}public boolean Verify(String idcard) {if (idcard.length() == 15) {idcard = uptoeighteen(idcard);}if (idcard.length() != 18) {return false;}String verify = idcard.substring(17, 18);if (verify.equals(getVerify(idcard))) {return true;}return false;}public String getVerify(String eightcardid) {int remaining = 0;if (eightcardid.length() == 18) {eightcardid = eightcardid.substring(0, 17);}if (eightcardid.length() == 17) {int sum = 0;for (int i = 0; i < 17; i++) {String k = eightcardid.substring(i, i + 1);ai[i] = Integer.parseInt(k);}for (int i = 0; i < 17; i++) {sum = sum + wi[i] * ai[i];}remaining = sum % 11;}return remaining == 2 ? "X" : String.valueOf(vi[remaining]);}public String uptoeighteen(String fifteencardid) {String eightcardid = fifteencardid.substring(0, 6);eightcardid = eightcardid + "19";eightcardid = eightcardid + fifteencardid.substring(6, 15);eightcardid = eightcardid + getVerify(eightcardid);return eightcardid;}public static void main(String[] args) {String idcard1 = "350211197607142059";String idcard2 = "350211197607442059";String idcard3 = "140222198911060538";IDCard idcard = new IDCard();System.out.println(idcard.Verify(idcard1));System.out.println(idcard.Verify(idcard2));System.out.println(idcard.Verify(idcard3));} }
