身份证号码正则截取生日golang和java实现

身份证分为一代身份证和二代身份证，一代身份证为15位、二代身份证为18位。

举例一代身份证：130503670401001

二代身份证：41140219891216321

?

一代身份证正则截取：^(\d{6})(\d{6})(.*)$

二代身份证正则截取:?^(\d{6})(\d{8})(.*)$

下面分别设java和golang的截取实现

package spring;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

/**
 * Created by banxia on 16/6/20.
 */
public class Test {


    public static  void  main(String[] args){


      //  String str = "411402198912166321";
         String str = "130503670401001";
        // ^(\d{6})(\d{8})(.*)      18位
        //^(\d{6})(\d{6})(.*)       15位
        Pattern pattern = Pattern.compile("^(\\d{6})(\\d{6})(.*)");

        Matcher matcher = pattern.matcher(str);
        if (matcher.find()) {


            String group = matcher.group(2);
            System.out.print(group);

        }


    }
}

package main

import (


)
import (
	"regexp"
	"fmt"
)

func main() {


var str string = "411402198912166321"

	reg,err :=  regexp.Compile("^(\\d{6})(\\d{8})(.*)")

	if err != nil {
		return
	}

	if reg.MatchString(str) == true {
		submatch := reg.FindStringSubmatch(str)
		fmt.Println(submatch)
		fmt.Println("date is ",submatch[2])
	}
