雇员查询系统java代码 查询雇员姓名,职位,领导姓名

java编写程序。。

import java.util.Scanner;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class EmployeeTest{

public EmployeeTest(){

}

public static void main(String[] args) {

Employee employee=getInfo();

System.out.println("您输入的雇员信息为：");

System.out.println("编号："+employee.getNumber()+

"\n姓名："+employee.getName()+

"\n部门号："+employee.getDeptNumber());

}

private static Employee getInfo(){

Employee employee=new Employee();

Scanner s=new Scanner(System.in);

String info="";

System.out.print("请输入姓名：");

info=s.nextLine();

employee.setName(info);

System.out.print("请输入编号：");

info=s.nextLine();

Pattern p=Pattern.compile("^[1-9]{1}\\d+$");

Matcher matcher=p.matcher(info);

while(!matcher.matches()){

System.out.print("格式错误，请重新输入编号：");

info=s.nextLine();

matcher=p.matcher(info);

}

employee.setNumber(Integer.parseInt(info));

System.out.print("请输入部门号：");

info=s.nextLine();

Pattern p2=Pattern.compile("^[1-5]{1}$");

matcher=p2.matcher(info);

while(!matcher.matches()){

System.out.print("格式错误，请重新输入部门号：");

info=s.nextLine();

matcher=p2.matcher(info);

}

employee.setDeptNumber(Integer.parseInt(info));

return employee;

}

}

public class Employee{

private String name;

private int number;

private int deptNumber;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getNumber() {

return number;

}

public void setNumber(int number) {

this.number = number;

}

public int getDeptNumber() {

return deptNumber;

}

public void setDeptNumber(int deptNumber) {

this.deptNumber = deptNumber;

}

}

一、java编写一个雇员类：1.属性：员工编号，姓名，职位，工资，2.方法包括：输出基本信息，计算

class Worker {

private String no;

private String name;

private String job;

private double wages;

public Worker() {

super();

}

public Worker(String no, String name, String job, double wages) {

super();

this.no = no;

this.name = name;

this.job = job;

this.wages = wages;

}

public String getWorkerInfo() {

return "员工编号：" + no + "；姓名：" + name + "；职位：" + job + "；工资：" + wages;

}

public double getPackage() {

return wages * 12;

}

}

class Salesman extends Worker {

private double bonus;

public Salesman() {

super();

}

public Salesman(double bonus) {

super();

this.bonus = bonus;

}

@Override

public String getWorkerInfo() {

return super.getWorkerInfo() + "；奖金：" + bonus;

}

@Override

public double getPackage() {

return super.getPackage() + bonus;

}

}

用Java定义一个类来描述公司雇员,类命名为Employee

公司雇员类代码：

/**

 * 公司雇员类

 * 

 * @author qd

 *

 */

public class Employee {

    private String first_name;

    private String last_name;

    // 雇员id

    private long employee_id;

    private String email;

    private String phone_number;

    // 入职日前

    private String hire_date;

    // 工作id

    private long job_id;

    private double salary;

    // 经理id号

    private long manager_id;

    public Employee() {

        super();

    }

    public Employee(String first_name, String last_name, long employee_id, String email, String phone_number,

            String hire_date, long job_id, double salary, long manager_id) {

        super();

        this.first_name = first_name;

        this.last_name = last_name;

        this.employee_id = employee_id;

        this.email = email;

        this.phone_number = phone_number;

        this.hire_date = hire_date;

        this.job_id = job_id;

        this.salary = salary;

        this.manager_id = manager_id;

    }

    public String getFirst_name() {

        return first_name;

    }

    public void setFirst_name(String first_name) {

        this.first_name = first_name;

    }

    public String getLast_name() {

        return last_name;

    }

    public void setLast_name(String last_name) {

        this.last_name = last_name;

    }

    public long getEmployee_id() {

        return employee_id;

    }

    public void setEmployee_id(long employee_id) {

        this.employee_id = employee_id;

    }

    public String getEmail() {

        return email;

    }

    public void setEmail(String email) {

        this.email = email;

    }

    public String getPhone_number() {

        return phone_number;

    }

    public void setPhone_number(String phone_number) {

        this.phone_number = phone_number;

    }

    public String getHire_date() {

        return hire_date;

    }

    public void setHire_date(String hire_date) {

        this.hire_date = hire_date;

    }

    public long getJob_id() {

        return job_id;

    }

    public void setJob_id(long job_id) {

        this.job_id = job_id;

    }

    public double getSalary() {

        return salary;

    }

    public void setSalary(double salary) {

        this.salary = salary;

    }

    public long getManager_id() {

        return manager_id;

    }

    public void setManager_id(long manager_id) {

        this.manager_id = manager_id;

    }

    @Override

    public String toString() {

        return "Employee [first_name=" + first_name + ", last_name=" + last_name + ", employee_id=" + employee_id

                + ", email=" + email + ", phone_number=" + phone_number + ", hire_date=" + hire_date + ", job_id="

                + job_id + ", salary=" + salary + ", manager_id=" + manager_id + "]";

    }

}

测试类代码以及效果：

JAVA创建5个雇员对象，设计程序找出五个雇员对象中年龄最大的员工，并将该员工的信息输出到控制台的代码。

class Employee {//雇员类

int age;

//所有信息

}

class Test{

List list = new ArrayList();

//声明创建五个对象

//比如Employee a = new Employee();

//......a.age = 30;

list.add(a);

//五个对象都加入List集合中

//然后遍历取出雇员查询系统java代码，比较年龄

for(int i=0;ilist.size;i++)

{

//取出年龄最大雇员查询系统java代码的对象 e

}

//输出e雇员查询系统java代码的所有信息

System.out.println(e.age + "其雇员查询系统java代码他信息");

}
