从 java 中输入 ID 用户打印日期

Question

我必须制作一个代码，输入用户名，然后输入 ID 号，格式为（1102199344556699 - 前 8 个字符是他的出生日期）。我的代码：

import java.time.format.DateTimeFormatter;
import java.time.temporal.TemporalAccessor;
import java.util.Locale;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) throws Exception {

        //user input
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter your name: ");
        int length = scanner.nextLine()
                .length();
        System.out.println(length);

        //user id input
        Scanner scanner2 = new Scanner(System.in);
        System.out.println("Enter your id number");
        String idNUmber = scanner2.nextLine();
        if (idNUmber.length() < 11) {
            throw new InvlaidIdException("invalid");
        } else {
        String dateOfBirth = idNUmber.substring(0, 8);

    //found this way,on the output is giving me from input -110219935656525
   //output is ok but as you can see on My output i get some extra things (please see OUTPUT)
        TemporalAccessor date = DateTimeFormatter.ofPattern("ddMMyyyy").withLocale(Locale.FRANCE).parse(dateOfBirth);
            System.out.println(date);
                }
            }
        }

输入用户 ID -110219935656525

输出：

This is  the birthday date: {},ISO resolved to 1993-02-11

我怎样才能摆脱 {}，ISO 解析为？谢谢，

经过更多研究我得到了我需要的输出:)

完整代码如下：

import java.util.Scanner;

public class Main {

    public static void main(String[] args) throws Exception {

        //user input
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter your name: ");
        int length = scanner.nextLine()
                .length();
        System.out.println(length);

        //id user input
        Scanner input = new Scanner(System.in);
        String civilIdStr = "";
        System.out.println("Enter your id number");
        civilIdStr = input.nextLine();
        if (civilIdStr.length() < 11) {
            throw new InvlaidIdException("invalid");
        } else {
// sout the date from the Id user input  (format DD-MM-YY)
                String dob = civilIdStr.substring(0, 8);
                System.out.println("Date of birth from user ID: " +
                        dob.substring(0, 2) + "/" +   //DATE
                        dob.substring(2, 4) + "/" +   //MONTH
                        dob.substring(6, 8));         //YEAR
            }
        }
    }

输出：

Enter your name: 
Victor

Enter your id number
11021993554644
Date of birth from user ID: 11/02/93
