手撸出来的，觉得不错就采纳（当然，最好自己也去打，对你有好处）

public class Student {

private String name;

private int stuNum;

private String birthday;//出生日期Date类型也好

private String profession;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getStuNum() {

return stuNum;

}

public void setStuNum(int stuNum) {

this.stuNum = stuNum;

}

public String getBirthday() {

return birthday;

}

public void setBirthday(String birthday) {

this.birthday = birthday;

}

public String getProfession() {

return profession;

}

public void setProfession(String profession) {

this.profession = profession;

}

我在main中声明了2个学生，截图如下：

public class Student {

// 姓名,学号,出生日期,专业
private String name;
private int id;
// 这里生日可以选择字符串形式。看你需求
private Date birthday;
private String prof;

public Student() {
}

public Student(String name, int id, Date birthday, String prof) {
this.name = name;
this.id = id;
this.birthday = birthday;
this.prof = prof;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public Date getBirthday() {
return birthday;
}

public void setBirthday(Date birthday) {
this.birthday = birthday;
}

public String getProf() {
return prof;
}

public void setProf(String prof) {
this.prof = prof;
}
}

直接给出具体代码
public class StudentDto implements Serializable {
private static final long serialVersionUID = -3824346741464362152L;
String student_id;
String name;
String birthday;
String professiona;
public StudentDto(String student_id, String name, String birthday,
String professiona) {
super();
this.student_id = student_id;
this.name = name;
this.birthday = birthday;
this.professiona = professiona;
}
@Override
public String toString() {
return "StudentDto [student_id=" + student_id + ", name=" + name
+ ", birthday=" + birthday + ", professiona=" + professiona
+ "]";
}
public String getStudent_id() {
return student_id;
}
public void setStudent_id(String student_id) {
this.student_id = student_id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
public String getProfessiona() {
return professiona;
}
public void setProfessiona(String professiona) {
this.professiona = professiona;
}

}

该方法主要提供了，问题中所需要的具体参数和必要的set，get方法，已经重构tostring和构造方法，防止远程调用增加了序列化数据。

整体其实没有什么难度，希望楼主多看看书，学习阶段不要老copy代码，对你没好处。

创建实体类主要是参数的命名合理，类型合理以及提供一些必要的方法。
