小错误

是一段数据库访问的例程
急用


import java.sql.*;
public class DBconn {
String DBDriver = "sun.jdbc.odbc.JdbcOdbcDriver";
String ConnStr = "jdbc:odbc:SPDSM";
Nonnection conn = null;
ResultSet rs = null;
public DBconn { //此句有错
try {
Class.forName(DBDriver);
//加载数据库驱动程序
}
catch(java.lang.ClassNotFoundException e) {
System.err.println("DBconn (): " + e.getMessage());
}
}
public ResultSet executeQuery(String sql) {
rs = null;
try {
conn = DriverManager.getConnection(ConnStr);
//与DBMS建立连接
Statement stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
}
catch(SQLException ex) {
System.err.println("aq.executeQuery: " + ex.getMessage());
}
return rs;
}
}

出错信息：

C:\My Documents\DBconn.java:13: Identifier expected.
public DBconn {
