java實現工資管理簡單程序
本文為大傢分享瞭java實現工資管理簡單程序的具體代碼，供大傢參考，具體內容如下
程序總體說明（ReadMe）：
總體分為四部分:
管理程序(staffmanagment.java)：
- 在這裡面使用瞭arraylist泛型來存放數據
- 博主正在想辦法把數據放進mysql，這樣讀取會更方便，而且數據不會消失
- 當然(也可以把數據存入txt文件)
import java.util.ArrayList;
//員工管理
public class staffmanagement {
ArrayList al = null;//員工信息在這裡面建立
public staffmanagement()
{
al = new ArrayList();
}
//成員方法
//添加新員工
public void addstaff(staff staff)
{
al.add(staff);
}
//根據工號查詢員工的信息
public void showInfo(String no)
{
int flag = 0;
for(int i=0; i<al.size(); i++)
{
staff staff= (staff)al.get(i);
if(staff.getNo().equals(no))
{
flag = 1;
System.out.println("員工"+(i+1)+"的信息是：");
System.out.print("姓名:"+staff.getName());
System.out.print(" 性別:"+staff.getSex());
System.out.print(" 年齡:"+staff.getAge());
System.out.print(" 工號:"+staff.getNo());
System.out.print(" 薪資:"+staff.getSalary());
System.out.print(" 工作:");
if(staff.getWork() == 1) System.out.println("common staff");
else if(staff.getWork() == 2) System.out.println("common manager");
else if(staff.getWork() == 3) System.out.println("head manager");
System.out.println(staff);
}
}
if(flag == 0)
System.out.println("該工號不存在");
}
//顯示所有員工信息
public void showAllInfo()
{
for(int i=0; i<al.size(); i++)
{

else if(staff.getWork() == 3) System.out.println("head manager");
System.out.println(staff);
}
}

if(staff.getNo().equals(no))
{

staff.setSalary(sal);
}
}
if(flag == 0)
System.out.println("找不到所查工號");
}
//根據工號刪除該員工的信息
public void deleteInfo(String no)
{
int flag = 0;
for(int i=0; i<al.size(); i++)
{
staff staff= (staff)al.get(i);
if(staff.getNo().equals(no))
{
flag = 1;
al.remove(i);
}
}
if(flag == 0)
System.out.println("找不到所查工號");
}
//統計當前公司的三個水平工資線
public void calSalary() {
if (al.isEmpty()) {
System.out.println("the stafflist is empty,please input the staff infomation");
System.out.println("please input the No 1 to add the staffinfo");
} else {
double totalSal = 0;
double minSal = ((staff) al.get(0)).getSalary();
double maxSal = ((staff) al.get(0)).getSalary();
for (int i = 0; i < al.size(); i++) {
staff staff = (staff) al.get(i);
totalSal += staff.getSalary();
if (minSal > staff.getSalary()) {
minSal = staff.getSalary();
}
if (maxSal < staff.getSalary()) {
maxSal = staff.getSalary();
}
}
System.out.println(al.size() + "個人的平均薪資為：" + totalSal / al.size());
System.out.println(al.size() + "個人的最低薪資為：" + minSal);
System.out.println(al.size() + "個人的最高薪資為：" + maxSal);
}
}
}
界面模塊(SalarySystem.java)
- 對不同員工的工資最低進行瞭限制，畢竟法律規定瞭不能給太低
- 年齡也是（至少得成年吧——你懂的）
- 職位還可以安排更多
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;

* @antuor:jeffw
* 員工界面為博主清風追夢的寫法
* 清風大大的blogs:http://www.cnblogs.com/qingfengzhuimeng/p/6509965.html

運行展示
2018.12.15更新：
現在還沒有想到怎麼用數據庫連接，不過新學習瞭file文件操作模式，現在把這種方式加入到員工管理裡面：
以下是增加內容：
else if(no.equals("10")) {
System.out.println("正在讀取中,請稍候...");
File file = new File("1.txt");
Scanner input = new Scanner(file);
while(input.hasNext()){
String name = input.nextLine();
String sex = input.nextLine();
int work = input.nextInt();
int age =input.nextInt();
input.nextLine();
String staffNo = input.nextLine();
double salary = input.nextDouble();
staff staff = null;
if (work == 1) {
staff = new staff(name, sex, age, staffNo, salary, work);
} else if(work == 2){
staff = new manager(name, sex, age, staffNo, salary, work);
}else if(work == 3 ) {
staff = new manager(name, sex, age, staffNo, salary, work);
}else{
System.out.println("不存在此職業");
}
sys.addstaff(staff);
System.out.println("導入成功");
}
接下來的想法是把重復的員工去除，想先通過提醒使用者導入員工後，刪除原有員工文件，然後在使用者退出前提示導入員工名單進行解決可能出現的員工重復問題
以上就是本文的全部內容，希望對大傢的學習有所幫助，也希望大傢多多支持WalkonNet。
