我写了两个java程序

FeePara1Item.java 源程序如下：

package dbbean;

public class FeePara1Item {

String FeePara1Code;
String FeePara1Name;

public FeePara1Item() {
}

public void setFeePara1Code(String code){
FeePara1Code = code;
}

public void setFeePara1Name(String name){
FeePara1Name = name;
}

public String getFeePara1Code(){
return FeePara1Code;
}

public String getFeePara1Name(){
return FeePara1Name;
}

}

上面这个编译通过了；

下面这个编译没有通过

package dbbean;
import java.sql.*;
import java.util.*;
//import dbbean;
//import FeePara1Item;

public class FeePara1 {

Vector FeePara1;

public FeePara1() {
FeePara1 = new Vector();
setFeePara1();
}

public void setFeePara1(){
dbbean db = new dbbean();
String strsql = "select scode,sname from tbl_fee1_c";
ResultSet rs = db.executeQuery(strsql);
while(rs.next()){
FeePara1Item item = new FeePara1Item();
item.setFeePara1Code(rs.getString(1));
item.setFeePara1Name(rs.getString(2));
FeePara1.addElement(item);
}
db.freeQuery();
}

public FeePara1Item getFeePara1Item(int i){
return (FeePara1Item)FeePara1.elementAt(i);
}

public int size(){
return FeePara1.size();
}

}

错误如下：
E:\webs\glgl\WEB-INF\classes\dbbean\FeePara1.java:29: cannot resolve symbol

public FeePara1Item getFeePara1Item(int i){

^
6 errors

问题：

我该如何改呢？

我刚刚开始写java，希望您能多多赐教！！
