在进行数据交互的过程中，我们必须将表抽象成一个类，然后对类进行调用，实现相关操作，在任何语言中都是差不多的。

我们需要根据表的属性来创建类

package employee;public class emp {    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    private String name ;    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }    private int age ;    public String getSex() {        return sex;    }    public void setSex(String sex) {        this.sex = sex;    }    private String sex ;    public int getWorkyears() {        return workyears;    }    public void setWorkyears(int workyears) {        this.workyears = workyears;    }    private int workyears ;    public String getCometime() {        return cometime;    }    public void setCometime(String cometime) {        this.cometime = cometime;    }    private String cometime ;    public String getOuttime() {        return outtime;    }    public void setOuttime(String outtime) {        this.outtime = outtime;    }    private String outtime ;    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    private  int id;    public String getPosition() {        return position;    }    public void setPosition(String position) {        this.position = position;    }    private String position ;    public emp(){};    public emp(int id,String name,int age ,int workyears ,String cometime,String outtime, String position,String sex){        this.id = id;        this.name = name;        this.sex= sex;        this.age = age;        this.workyears = workyears;        this.cometime = cometime;        this.outtime = outtime;        this.position = position;    };    @Override    public String toString() {        return "members{" +                "id=" + id +                ", sex=" + sex +                ", name=" + name +                ", age=" + age +                ", workyears=" + workyears +                ", cometime=" + cometime +                ", outtime=" + outtime +                ", position=" + position +                '}';    }}
