收起

在上一次的课堂上完成了数据库的连接，现在开始做实体类以及sql语句的编写

Record类：

package com.example.app_02.entity;

public class Record {
    private String startTime;
    private String endTime;
    private String record;

    public Record() {
    }

    public Record(String startTime, String endTime, String record) {
        this.startTime = startTime;
        this.endTime = endTime;
        this.record = record;
    }

    /**
     * 获取
     *
     * @return startTime
     */
    public String getStartTime() {
        return startTime;
    }

    /**
     * 设置
     *
     * @param startTime
     */
    public void setStartTime(String startTime) {
        this.startTime = startTime;
    }

    /**
     * 获取
     *
     * @return endTime
     */
    public String getEndTime() {
        return endTime;
    }

    /**
     * 设置
     *
     * @param endTime
     */
    public void setEndTime(String endTime) {
        this.endTime = endTime;
    }

    /**
     * 获取
     *
     * @return record
     */
    public String getRecord() {
        return record;
    }

    /**
     * 设置
     *
     * @param record
     */
    public void setRecord(String record) {
        this.record = record;
    }

    public String toString() {
        return "startTime: " + startTime + ", endTime: " + endTime + "\nrecord: " + record + "\n";
    }
}
User类

package com.example.app_02.entity;

public class User {
    private String username;
    private String password;

    public User() {
    }

    public User(String username, String password) {
        this.username = username;
        this.password = password;
    }

    /**
     * 获取
     * @return username
     */
    public String getUsername() {
        return username;
    }

    /**
     * 设置
     * @param username
     */
    public void setUsername(String username) {
        this.username = username;
    }

    /**
     * 获取
     * @return password
     */
    public String getPassword() {
        return password;
    }

    /**
     * 设置
     * @param password
     */
    public void setPassword(String password) {
        this.password = password;
    }

    public String toString() {
        return "User{username = " + username + ", password = " + password + "}";
    }
}
UserInfom类

package com.example.app_02.entity;

public class UserInfo {
    private String studentid;
    private String name;
    private String phonenumber;
    private String classname;

    public UserInfo() {
    }

    public UserInfo(String studentid, String name, String phonenumber, String classname) {
        this.studentid = studentid;
        this.name = name;
        this.phonenumber = phonenumber;
        this.classname = classname;
    }

    /**
     * 获取
     * @return studentid
     */
    public String getStudentid() {
        return studentid;
    }

    /**
     * 设置
     * @param studentid
     */
    public void setStudentid(String studentid) {
        this.studentid = studentid;
    }

    /**
     * 获取
     * @return name
     */
    public String getName() {
        return name;
    }

    /**
     * 设置
     * @param name
     */
    public void setName(String name) {
        this.name = name;
    }

    /**
     * 获取
     * @return phonenumber
     */
    public String getPhonenumber() {
        return phonenumber;
    }

    /**
     * 设置
     * @param phonenumber
     */
    public void setPhonenumber(String phonenumber) {
        this.phonenumber = phonenumber;
    }

    /**
     * 获取
     * @return classname
     */
    public String getClassname() {
        return classname;
    }

    /**
     * 设置
     * @param classname
     */
    public void setClassname(String classname) {
        this.classname = classname;
    }

    public String toString() {
        return "User{studentid = " + studentid + ", name = " + name + ", phonenumber = " + phonenumber + ", classname = " + classname + "}";
    }
}
