一、需求和算法

1. 需求

   1. 使用 Java 中 util 包通过键盘输入身份证号。
   2. 使用算法校验身份证号是否合法。
   3. 根据身份证号获取用户出生地。
   4. 根据身份证号获取用户生日。
   5. 根据身份证号获取用户性别。
   6. 打印出生地、生日、性别。

2. 算法

   1. 取出身份证号前 17 位与指定系数相乘。系数表如下：

      

   2. 把相乘的结果累加起来。

   3. 用累加结果对 11 求余。

   4. 根据余数对应下表找到身份证号的末尾数。

      

   5. 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：

1. 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);}
   }
   

2. 运行结果：

   

三、处理末尾数为 x 的身份证号

1. 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);}
   }
   

2. 运行结果：

   

四、校验身份证号

1. 定义字符串截取函数

   1. 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);}}
      

   2. 运行结果：

      

2. 定义校验函数

   1. 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);}}
      

   2. 运行结果：

      

      

五、获取地址信息

1. 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 =
