考勤周汇总写法思路java

考勤周汇总的写法思路可以分为以下几个步骤：

1. 获取考勤数据：从数据库或者文件中读取考勤数据，可以使用 JDBC 或者文件读写操作实现。

2. 统计考勤数据：对考勤数据进行统计，计算出每个员工的出勤天数、迟到次数、早退次数等信息。

3. 生成周报表：将统计结果按照一定的格式输出到周报表中，可以使用文本文件或者 Excel 表格等形式。

4. 发送周报表：将生成的周报表发送给相关人员，可以通过邮件、微信等方式发送。

下面是一个简单的 Java 代码示例，演示了如何实现考勤周汇总：

import java.io.*;
import java.sql.*;
import java.text.SimpleDateFormat;
import java.util.*;

public class AttendanceSummary {
    public static void main(String[] args) {
        // 1. 获取考勤数据
        List<AttendanceRecord> records = getAttendanceRecords();

        // 2. 统计考勤数据
        Map<String, AttendanceSummaryData> summaryDataMap = new HashMap<>();
        for (AttendanceRecord record : records) {
            String employeeId = record.getEmployeeId();
            AttendanceSummaryData summaryData = summaryDataMap.getOrDefault(employeeId, new AttendanceSummaryData());
            summaryData.addAttendanceRecord(record);
            summaryDataMap.put(employeeId, summaryData);
        }

        // 3. 生成周报表
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        String report = "员工ID\t出勤天数\t迟到次数\t早退次数\n";
        for (Map.Entry<String, AttendanceSummaryData> entry : summaryDataMap.entrySet()) {
            String employeeId = entry.getKey();
            AttendanceSummaryData summaryData = entry.getValue();
            report += employeeId + "\t" + summaryData.getAttendanceDays() + "\t" + summaryData.getLateTimes() + "\t" + summaryData.getEarlyLeaveTimes() + "\n";
        }

        // 4. 发送周报表
        sendReport(report);
    }

    private static List<AttendanceRecord> getAttendanceRecords() {
        // TODO: 从数据库或者文件中读取考勤数据
        return new ArrayList<>();
    }

    private static void sendReport(String report) {
        // TODO: 发送周报表给相关人员
    }
}

class AttendanceRecord {
    private String employeeId;
    private Date date;
    private boolean isLate;
    private boolean isEarlyLeave;

    public AttendanceRecord(String employeeId, Date date, boolean isLate, boolean isEarlyLeave) {
        this.employeeId = employeeId;
        this.date = date;
        this.isLate = isLate;
        this.isEarlyLeave = isEarlyLeave;
    }

    public String getEmployeeId() {
        return employeeId;
    }

    public Date getDate() {
        return date;
    }

    public boolean isLate() {
        return isLate;
    }

    public boolean isEarlyLeave() {
        return isEarlyLeave;
    }
}

class AttendanceSummaryData {
    private int attendanceDays;
    private int lateTimes;
    private int earlyLeaveTimes;

    public void addAttendanceRecord(AttendanceRecord record) {
        attendanceDays++;
        if (record.isLate()) {
            lateTimes++;
        }
        if (record.isEarlyLeave()) {
            earlyLeaveTimes++;
        }
    }

    public int getAttendanceDays() {
        return attendanceDays;
    }

    public int getLateTimes() {
        return lateTimes;
    }

    public int getEarlyLeaveTimes() {
        return earlyLeaveTimes;
    }
}
