package cn.itcast.domain;
public class Student {
private String idcard;
private String examid;
private String name;
private String location;
private double grade;
public String getIdcard() {
return idcard;
}
public void setIdcard(String idcard) {
this.idcard = idcard;
}
public String getExamid() {
return examid;
}
public void setExamid(String examid) {
this.examid = examid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
public double getGrade() {
return grade;
}
public void setGrade(double grade) {
this.grade = grade;
}
}
这事操作代码
import cn.itcast.utils.XmlUtils;
public class StudentDao {
public void add(String s){
try {
Document document = XmlUtils.getDocument();
//创建封装学生信息的标签
Element student_tag = document.createElement("student");
student_tag.setAttribute("idcard", s.getIdcard());
student_tag.setAttribute("examid", s.getExamid());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
这里的getIdcard()和getExamid（）方法会出现The method getIdcard() is undefined for the type String的错误啊！
