一、vo实体类
package HTML;
public class Student {
private String name;
private int age;//年龄
private String number;//学号
private int grade;//成绩
private String dateTime;
public String getDateTime() {
return dateTime;
}
public void setDateTime(String dateTime) {
this.dateTime = dateTime;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public int getGrade() {
return grade;
}
public void setGrade(int grade) {
this.grade = grade;
}
}
