getstuID()出现了标题这个错误
我的 people 类
public class people {
private String stuID;
private String name;
private int score;
people(){}
public String getstuID() {
return this.stuID;
}
public void setstuID(String id) {
this.stuID = id;
}
public String getname() {
return this.name;
}
public void setname(String name) {
this.name = name;
}
public int getscore() {
return this.score;
}
public void setscore(int score) {
this.score = score;
}
}
下面的是我出错的那个类
import java.sql.*;
import java.util.ArrayList;
import java.util.List;
public class idea {
private static idea instance = new idea();
public static idea getInstance() {
return instance;
}
private idea() {}
public boolean saveStudent(people stu) {
boolean result = false;
Connection conn = null;
try {
conn = JdbcAccess.getConnection();
String sqlInset = "insert into CJGL.student(stuID, Name, score) values(?, ?, ?)";
PreparedStatement stmt = conn.prepareStatement(sqlInset);
stmt.setString(1, stu.getstuID());
stmt.setString(2, stu.getname());
stmt.setInt(3, stu.getscore());
int i = stmt.executeUpdate();
if(i==1) {
result = true;
}
}catch(SQLException e) {
e.printStackTrace();
}finally {
try {
conn.close();
}catch(SQLException e) {
e.printStackTrace();
}
}
return result;
}
public List<people> selectPeople(){
List<people> peoList = new ArrayList<people>();
Connection conn = null;
try {
conn = JdbcAccess.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from CJGL.student");
while(rs.next()) {
people stu = new people();
stmt.setstuID(1, stu.getstuID("ID"));
stmt.setname(2, stu.getname("name"));
stmt.setscore(3, stu.getscore("score"));
peoList.add(stu);
}
}catch(Exception e) {
e.printStackTrace();
}finally {
try {
conn.close();
}catch(SQLException e) {
e.printStackTrace();
}
}
return peoList;
}
}
我的解答思路和尝试过的方法
我试过直接点那个
然后错误就去到setstuID()那边了
楼主是初学者,这该咋整
