JAVA生成企业组织机构代码、营业执照代码、税务登记号码、统一社会信用代码并校验

生成代码及校验代码如下：

import java.util.HashMap;
import java.util.Map;
import java.util.Random;

public class ProductData {
    //生成企业组织机构代码
    public static String getORGANIZATION_CODE(){
        int [] in = { 3, 7, 9, 10, 5, 8, 4, 2 };
        String data = "";

        int a = 0;
        //随机生成英文字母和数字
        for (int i = 0; i < in.length; i++){
            String word = getCharAndNumr(1,0).toUpperCase();
            if (word.matches("[A-Z]")) {
                a += in[i] * getAsc(word);
            }else{
                a += in[i] * Integer.parseInt(word);
            }
            data += word;
        }
        //确定序列
        int c9 = 11 - a % 11;
        //判断c9大小，安装 X 0 或者C9
        if (c9 == 10) {
            yz = "X";
        } else if (c9 == 11) {
            yz = "0";
        } else {

        }

        return data.toUpperCase();
    }

    //生成营业执照代码

        //拼凑
