使用Java语言编写程序，输出某公司员工的基本信息
public class Test0 {
public static void main(String[] args) {
Employee ZhangSan = new Employee("001", "张三", '男', "销售部", 6000, 1000, "普通员工");
Employee LiSi = new Employee("002", "李四", '女', "人事部", 7000, 2000, "超级员工");
System.out.println(ZhangSan.toString()); //打印张三信息
System.out.println(LiSi.toString()); //打印李四信息
}
}
class Employee{
private String id; //员工ID
private String name; //姓名
private char sex; //性别
private String department; //部门
private int basic_salary; //基本工资
private int extra_salary; //薪金
private String classify; //类别
/**
* 构造方法
*/
public Employee(String id, String name, char sex, String department,
int basic_salary, int extra_salary, String classify) {
this.id = id;
this.name = name;
this.sex = sex;
this.department = department;
this.basic_salary = basic_salary;
this.extra_salary = extra_salary;
this.classify = classify;
}
public Employee(){
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public char getSex() {
return sex;
}
public void setSex(char sex) {
this.sex = sex;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
public int getBasic_salary() {
return basic_salary;
}
public void setBasic_salary(int basic_salary) {
this.basic_salary = basic_salary;
}
public int getExtra_salary() {
return extra_salary;
}
public void setExtra_salary(int extra_salary) {
this.extra_salary = extra_salary;
}
public String getClassify() {
return classify;
}
public void setClassify(String classify) {
this.classify = classify;
}
public String toString(){
String str ="[员工ID:"+id+"|姓名:"+name+"|性别:"+sex+
"|部门:"+department+"|基本工资:+"+basic_salary+
"|薪金:"+extra_salary+"|类别:"+classify+"]";
return str;
}
}

Q1: 用Java编写一个员工类程序:1.属性：员工编号，员工姓名，基本工资，奖金，2.构造方法：至少两个
用Java编写一个员工类程序:1.属性员工信息代码java语言：员工编号员工信息代码java语言，员工姓名员工信息代码java语言，基本工资员工信息代码java语言，奖金，2.构造方法员工信息代码java语言：至少两个。如下：
package com.test;
public class Employee {
/**
* 员工编号
*/
private String number;
/**
* 员工姓名
*/
private String name;
/**
* 员工薪水
*/
private double salary;
/**
* 无参数构造函数
*/
public Employee() {
}
/**
* 给属性赋值构造函数
* @param number
* @param name
* @param salary
*/
public Employee(String number, String name, double salary) {
super();
this.number = number;
this.name = name;
this.salary = salary;
}
public static void main(String[] args) {
//员工一，并且构造函数里设置值
Employee e1 = new Employee("e0001", "xiaoming", 5000.0);
System.out.println("员工一：" + e1);
//员工二，用set设置值，get的话可以获取到员工某个属性
Employee e2 = new Employee();
e2.setName("小二");
e2.setNumber("e0002");
e2.setSalary(5500.1);
System.out.println("员工二：" + e2);
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getSalary() {
return salary;
}
public void setSalary(double salary) {
this.salary = salary;
}
@Override
public String toString() {
return "Employee [number=" + number + ", name=" + name + ", salary=" +
salary + "]";
}
}
运行结果：
员工一：Employee [number=e0001, name=xiaoming, salary=5000.0]
员工二：Employee [number=e0002, name=小二, salary=5500.1]
Q2: 利用java代码,编写JDBC连接数据库新增员工信息的步骤. 员工信息表:t_emp(id int？
第一步：新建数据库
连接的是本地localhost，新建一个新的数据库名是jdbctest
然后建表t_emp
不会的话可通过执行下方的sql语句建表
CREATE TABLE `t_emp` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
`salary` double DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
第二步：新建java项目
新建完以后添加mysql驱动的jar包，jar包自己下载
在项目上右键鼠标属性，然后
添加jar包，我这里已经加载过了
第三步：编写代码
package com.gf;
import java.sql.DriverManager;
import java.sql.SQLException;
import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;
public class Test {
public static void main(String[] args) throws Exception {
int flag=0;
//1.加载驱动
Class.forName("com.mysql.jdbc.Driver");
//2.获取连接
Connection conn=(Connection) DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/jdbctest?user=rootpassword=123456useUnicode=truecharacterEncoding=UTF-8");
//3.创建statement
Statement sm=(Statement) conn.createStatement();
//4.执行sql语句
flag=sm.executeUpdate("insert into t_emp(name,salary) values('菲菲',34.9)");
if(flag!=0) {
System.out.println("员工信息增加成功");
}else {
System.out.println("添加失败");
}
}
}
注意点：
---------------------------------------------------------------------------------
DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/jdbctest?user=rootpassword=123456useUnicode=truecharacterEncoding=UTF-8");
这里需要修改自己本机的连接信息，不然会出现连接失败
