why can't i compile the 'ControlUser.java' file below?

there are two files
1st file : Mahasiswa.java
---------------------------------
package model.bean;
public class Mahasiswa
{
private String nim;
private String nama;

public Mahasiswa() {}

public Mahasiswa(String nim, String nama)

setNim(nim);
setNama(nama);
}

public void setNim(String n)
{
nim = n;
}

public void setNama(String n)

public String getNim()
{
return nim;
}

public String getNama()

}
}

2nd file :ControlUser.java
------------------------------------------
package model;
import model.bean.Mahasiswa;
import java.sql.*;
import java.util.Vector;

public class ControlUser {

private String dbPath;
Connection con = null;
Statement st = null;

public ControlUser(String db){
dbPath = db;
}

//koneksi ke database

public void connectDb(){
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection("jdbc:odbc:driver={Mic rosoft Access Driver (*.mdb)};DBQ="+dbPath);
st = con.createStatement(1004,1008);
}catch(Exception e){ e.printStackTrace();}
}
public void closeDb(){
try{
st.close();
con.close();
}catch(Exception e){ e.printStackTrace();}
}

//ambil data mahasiswa dari database
public Mahasiswa [] loadMahasiswa(String query)
{
try{
connectDb();
ResultSet rs = st.executeQuery(query);
Vector <Mahasiswa> v = new Vector <Mahasiswa>();
while (rs.next()){
Mahasiswa temp = new Mahasiswa(rs.getString("nim"), rs.getString("nama"));
v.add(temp);
}
Mahasiswa [] arr = new Mahasiswa[v.size()];
v.toArray(arr);
rs.close();
closeDb();
return arr;
}catch(Exception e){e.printStackTrace();}
return null;
}
}
-------------------------------------------

thanx for your answer :)

Hi,

Try the following syntax to compile the code
1. Go to the directory where your .java files were placed and try the following command

javac -d . *.java

-d tells the compiler to create folder structure according to the package structure and place the class file in that directory.
And the '.' says that the directories should be created in the current directory.
*.java to compile all java files.

Hope it solves your problem.

NOTE: you need to have java 1.5 to use generic objects.

Rakesh
