我写的程序如下:
import java.sql.*;
public class database{
public static void main(String[] args){
Connection conn=null;
Statement st=null;
ResultSet rs=null;
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance(); // JDBC-ODBC bridge
String dbUrl = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};";
dbUrl += "DBQ=d:\\Java\\student.mdb";
conn =DriverManager.getConnection(dbUrl, "", "");
st=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,Result.CONCUR_READ_ONLY);
String sql="select * from student";
rs=st.executeQuery(sql);
if (rs.next()){
System.out.println("have data");
}
else{
System.out.println("no data");
}
}
catch (SQLException ex){
while (ex!=null){
System.out.println("message"+ex.getMessage());
}
}
catch(Exception e){
e.printStackTrace();

}

finally {
try {
if (st!=null)
{st.close();}
if (conn!=null)
{conn.close();}
}
catch(SQLException ex){
System.out.println("message"+ex.getMessage());
}
}
}

}

提示这一句错了
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstace();
请问这是怎么回事?
