实现全国组织机构代码校验

全国组织机构代码的基本组成：由8位数字（或大写字母）和1位数字（或大写字母）组成；如下图

全国组织机构代码详情：全国组织机构代码编码规则
校验代码的实现如下：
/**
* Desc: 全国组织机构代码 校验
* Created 2016/6/6.
*/
public class Regex_OrganizationCertificate {
private static String str1 = "D2143569-X";// 测试
private static String str2 = "74371976-1";// 测试
private static String str3 = "L1832212-3";// 测试
private static String isOrganizationCertificate = "true";
private static String error_OrganizationCertificate ="输入的机构代码错误，请核对后再输！";
private static String error_OrganizationCertificate_num ="输入的机构代码位数不对，请核对后再输！";
/**
* 加权因子
*/
private static int power[] = {3,7,9,10,5,8,4,2};

public static void main(String[] args) {
String temp = str2;
System.out.println(temp);
isOrganizationCertificate(temp);
}

/**
* 判断机构代码是不是有效的
* @param organizationCertificate
* @return
*/
public static String isOrganizationCertificate(String organizationCertificate) {
String temp = organizationCertificate.toUpperCase();
if (temp.contains("-")) {
temp = temp.replace("-", "");
System.out.println(temp);
}
if(temp.length()!=9){
System.out.println(error_OrganizationCertificate_num);
return error_OrganizationCertificate_num;
}
// 获取前面8位
String pre8 = temp.substring(0,8);
char[] pre8chars = pre8.toCharArray();// 0~z;
// 获取校验码
String code = temp.substring(8,9);
boolean isCode = isCode(code,sum(pre8chars));
System.out.println(isCode?isOrganizationCertificate:error_OrganizationCertificate);
return isCode?isOrganizationCertificate:error_OrganizationCertificate;
}

/**
* 求和
* @param bit
* @return
*/
private static int sum(char[] bit){
int sum = 0;
for(int i=0;i<bit.length;i++){
int intTemp = bit[i]>'9'?(bit[i]-'A'+10):Integer.parseInt(bit[i]+"");
System.out.print(" "+intTemp);
sum +=intTemp*power[i];
}
System.out.println();
System.out.println(sum);
return sum;
}

/**
* 判断机构代码的校验码和计算出的校验码是否一致
* @param a
* @param b
* @return
*/
private static boolean isCode(String a,int b){
String codeTEmp = (11- b%11)==10?"X":(11- b%11)==11?0+"":(11- b%11)+"";
System.out.println(codeTEmp);
return a.equals(codeTEmp);
}
