运用java，写一个公司考勤系统，能够实现录入修改查询职员的缺勤记录，统计职员的旷工记录

由于题目较为简单，且缺乏细节，因此只提供一个基本的代码框架，供参考：

import java.util.HashMap;
import java.util.Map;
import java.util.Scanner;

public class AttendanceSystem {
    private Map<String, Integer> absentCounts; // 记录职员缺勤天数，key为职员姓名，value为缺勤天数

    public AttendanceSystem() {
        this.absentCounts = new HashMap<>();
    }

    // 录入职员缺勤记录
    public void addAbsentRecord(String name, int count) {
        if (absentCounts.containsKey(name)) {
            int currentCount = absentCounts.get(name);
            absentCounts.put(name, currentCount + count);
        } else {
            absentCounts.put(name, count);
        }
    }

    // 修改职员缺勤记录
    public void modifyAbsentRecord(String name, int count) {
        if (absentCounts.containsKey(name)) {
            absentCounts.put(name, count);
        } else {
            System.out.println("职员不存在！");
        }
    }

    // 查询职员缺勤记录
    public int queryAbsentRecord(String name) {
        if (absentCounts.containsKey(name)) {
            return absentCounts.get(name);
        } else {
            System.out.println("职员不存在！");
            return -1;
        }
    }

    // 统计职员旷工记录
    public int countAbsenteeism(String name) {
        if (absentCounts.containsKey(name)) {
            int count = absentCounts.get(name);
            if (count >= 7) {
                return count - 6; // 超过6天算旷工
            } else {
                return 0;
            }
        } else {
            System.out.println("职员不存在！");
            return -1;
        }
    }

    // 测试代码
    public static void main(String[] args) {
        AttendanceSystem system = new AttendanceSystem();

        // 添加职员缺勤记录
        system.addAbsentRecord("张三", 3);
        system.addAbsentRecord("李四", 5);
        system.addAbsentRecord("王五", 7);

        // 修改职员缺勤记录
        system.modifyAbsentRecord("李四", 4);

        // 查询职员缺勤记录
        System.out.println(system.queryAbsentRecord("张三"));
        System.out.println(system.queryAbsentRecord("李四"));
        System.out.println(system.queryAbsentRecord("王五"));
        System.out.println(system.queryAbsentRecord("赵六"));

        // 统计职员旷工记录
        System.out.println(system.countAbsenteeism("张三"));
        System.out.println(system.countAbsenteeism("李四"));
        System.out.println(system.countAbsenteeism("王五"));
        System.out.println(system.countAbsenteeism("赵六"));
    }
}
