一、需求和算法
-
需求
- 使用 Java 中 util 包通过键盘输入身份证号。
- 使用算法校验身份证号是否合法。
- 根据身份证号获取用户出生地。
- 根据身份证号获取用户生日。
- 根据身份证号获取用户性别。
- 打印出生地、生日、性别。
-
算法
-
取出身份证号前 17 位与指定系数相乘。系数表如下：
-
把相乘的结果累加起来。
-
用累加结果对 11 求余。
-
根据余数对应下表找到身份证号的末尾数。
-
判断用户输入的身份证号最后一位与余数对应的尾数是否相等。若相等表示输入的身份证号无误。反之有误。
-
二、键盘输入：
-
代码：
import java.util.*; public class IdNumber { public static void main(String[] args) { // 键盘输入身份证号 Scanner scanner = new Scanner(System.in); System.out.println("请输入您的身份证号："); String idNumber = scanner.nextLine(); System.out.println("您的身份证号为：" + idNumber); } } -
运行结果：
三、处理末尾数为 x 的身份证号
-
代码:
import java.util.*; public class IdNumber { public static void main(String[] args) { // 键盘输入身份证号 Scanner scanner = new Scanner(System.in); System.out.println("请输入您的身份证号："); String idNumber = scanner.nextLine(); // 处理最后一位为 x 的情况，小写转大写 idNumber = idNumber.toUpperCase(); System.out.println("您的身份证号为：" + idNumber); } } -
运行结果：
四、校验身份证号
-
定义字符串截取函数
-
代码：
import java.util.*; public class IdNumber { // 入口 public static void main(String[] args) { // 键盘输入身份证号 Scanner scanner = new Scanner(System.in); System.out.println("请输入您的身份证号："); String idNumber = scanner.nextLine(); // 处理最后一位为 x 的情况，小写转大写 idNumber = idNumber.toUpperCase(); // 测试代码 System.out.println("您的身份证号前六位：" + getStr(idNumber,0,5)); } // 截取字符串的方法 public static String getStr(String str,int a,int b) { b++; return str.substring(a,b); } } -
运行结果：
-
-
定义校验函数
-
代码：
import java.util.*; public class IdNumber { // 入口 public static void main(String[] args) { // 键盘输入身份证号 Scanner scanner = new Scanner(System.in); System.out.println("请输入您的身份证号："); String idNumber = scanner.nextLine(); // 处理最后一位为 x 的情况，小写转大写 idNumber = idNumber.toUpperCase(); // 判断身份证号是否合法 Boolean idLegit = judgeId(idNumber); System.out.println(idLegit); } // 判断身份证号是否合法 public static Boolean judgeId(String id) { Boolean result = true; // 长度不等于 18 位 if(id.length() != 18) return false; // 系数算法 String tempId = getStr(id,0,16); int[] coeff = {7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2}; char[] end = {'1','0','X','9','8','7','6','5','4','3','2'}; int sum = 0; for (int i = 0; i < tempId.length(); i++) { int bye = tempId.charAt(i) - '0'; sum += bye * coeff[i]; } sum %= 11; if(end[sum] != getStr(id,17,17).charAt(0)) result = false; return result; } // 截取字符串的方法 public static String getStr(String str,int a,int b) { b++; return str.substring(a,b); } } -
运行结果：
-
五、获取地址信息
-
定义函数：
import java.util.*; public class IdNumber { // 入口 public static void main(String[] args) { // 键盘输入身份证号 Scanner scanner = new Scanner(System.in); System.out.println("请输入您的身份证号："); String idNumber = scanner.nextLine(); // 处理最后一位为 x 的情况，小写转大写 idNumber = idNumber.toUpperCase(); // 判断身份证号是否合法 Boolean idLegit = judgeId(idNumber); if(idLegit) { String address = getAddress(getStr(idNumber,0,5)); System.out.println("您的居住地：" + address); } else System.out.println("身份证号有误！请重启程序"); } // 判断身份证号是否合法 public static Boolean judgeId(String id) { Boolean result = true; // 长度不等于 18 位 if(id.length() != 18) return false; // 系数算法 String tempId = getStr(id,0,16); int[] coeff = {7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2}; char[] end = {'1','0','X','9','8','7','6','5','4','3','2'}; int sum = 0; for (int i = 0; i < tempId.length(); i++) { int bye = tempId.charAt(i) - '0'; sum += bye * coeff[i]; } sum %= 11; if(end[sum] != getStr(id,17,17).charAt(0)) result = false; return result; } // 截取字符串的方法 public static String getStr(String str,int a,int b) { b++; return str.substring(a,b); } // 获取地址信息 public static String getAddress(String num) { String str0 = getStr(num,0,1); String str1 = getStr(num,2,3); String str2 = getStr(num,4,5); String address = ""; switch (str0) { case "11": address += "北京-";
