使用java编写程序实现输入员工工资,获得员工的平均工资,要求使用象数组类型的
一：将员工姓名、工资封装成一个对象
public class Staff {
private String name;
private int salary;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getSalary() {
return salary;
}
public void setSalary(int salary) {
this.salary = salary;
}
public Staff(String name, int salary) {
super();
this.name = name;
this.salary = salary;
}
}
二：初始化一个数组，算平均工资
public class Average {
public static void main(String[] args) {
Staff staffs[] = {new Staff("zhangsan", 1000), new Staff("lisi", 1100), new Staff("wangwu", 1200)};
int sum = 0;
for(Staff staff : staffs) {
sum = sum + staff.getSalary();
}
System.out.println("员工人数：" + staffs.length + " 总工资：" + sum + " 平均工资：" + sum / staffs.length);
}
}
java计算工资
person类：
public abstract class Person {
public double pay; // 总工资
public int hour; // 课时
public double countPay(int hour) {
return pay;
}
}
助教类：
public class Assistant extends Person {
public final double BASE_PAY = 800; // 基本工资
public final double HOUR_PAY = 25; // 每课时的费用
public double countPay(int hour) {
pay = BASE_PAY + hour * HOUR_PAY;
return pay;
}
}
讲师类：
public class Instructor extends Person {
public final double BASE_PAY = 1000; // 基本工资
public final double HOUR_PAY = 35; // 每课时的费用
public double countPay(int hour) {
pay = BASE_PAY + hour * HOUR_PAY;
return pay;
}
}
副教授类：
public class AssistantProfesson extends Person {
public final double BASE_PAY = 1200; // 基本工资
public final double HOUR_PAY = 40; // 每课时的费用
public double countPay(int hour) {
pay = BASE_PAY + hour * HOUR_PAY;
return pay;
}
}
教授类：
public class Professor extends Person {
public final double BASE_PAY = 1400; // 基本工资
public final double HOUR_PAY = 50; // 每课时的费用
public double countPay(int hour) {
pay = BASE_PAY + hour * HOUR_PAY;
return pay;
}
}
测试类：
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class Test {
public static void main(String[] args) {
System.out.println("人员类型如下：");
System.out.println("1 = 助教\r\n2 = 讲师\r\n3 = 副教授\r\n4 = 教授");
System.out.print("请选择：");
BufferedReader personType = new BufferedReader(new InputStreamReader(
System.in));
String type = null;
int hour = 0;
try {
type = personType.readLine();
} catch (Exception e) {
e.printStackTrace();
}
if (type.matches("[1-4]{1}")) {
switch (Integer.valueOf(type)) {
case 1:
hour = getHour();
if(hour == 0){return;}
Person p1 = new Assistant();
double pay1 = p1.countPay(hour);
System.out.println("助教工作" + hour + "课时的工资为：" + pay1);
break;
case 2:
hour = getHour();
if(hour == 0){return;}
Person p2 = new Instructor();
double pay2 = p2.countPay(hour);
System.out.println("讲师工作" + hour + "课时的工资为：" + pay2);
break;
case 3:
hour = getHour();
if(hour == 0){return;}
Person p3 = new AssistantProfesson();
double pay3 = p3.countPay(hour);
System.out.println("副教授工作" + hour + "课时的工资为：" + pay3);
break;
case 4:
hour = getHour();
if(hour == 0){return;}
Person p4 = new Professor();
double pay4 = p4.countPay(hour);
System.out.println("教授工作" + hour + "课时的工资为：" + pay4);
break;
}
} else {
System.out.println("输入数据错误！程序提前推出！");
return;
}
}
public static int getHour() {
System.out.print("请输入工作时间：");
BufferedReader hours = new BufferedReader(new InputStreamReader(
System.in));
String strHour = null;
int hour = 0;
try {
strHour = hours.readLine();
} catch (Exception e) {
e.printStackTrace();
}
if (strHour.matches("^[0-9]+?")) {
hour = Integer.parseInt(strHour);
} else {
System.out.println("输入参数不正确！程序提前推出！");
}
return hour;
}
}
求一段简单的JAVA代码 要求员工工资管理系统的一个增删改查代码，谢谢了
对数据库进行增删改查？
以下是 sql server 2013+java.实现的是对MSC对象的增删改查.
需要下载连接驱动程序：com.microsoft.sqlserver.jdbc.SQLServerDriver
网上搜一下就行
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
class MSC
{
public String MscID;
public String MscName;
public String MscCompany;
public float MscLongitude;
public float MscLatitude;
public float MscAltitude;
public MSC(String MscID, String MscName, String MscCompany,
float MscLongitude, float MscLatitude,float MscAltitude){
this.MscID = MscID;
this.MscName = MscName;
this.MscCompany = MscCompany;

this.MscAltitude = MscAltitude;
}
}
public class sqlserverjdbc {

String userPwd = "123"; //密码

try {
Class.forName(driverName);
dbConn =DriverManager.getConnection(dbURL, userName, userPwd);
} catch (Exception e) {
e.printStackTrace();
}
return dbConn;
}
public void printUserInfo(){

}
con.close();
sta.close();
rs.close();
} catch (SQLException e) {

}
System.out.println("打印完成\n");
}
public void delete(String MscID){

public static void main(String args[]){
