package edu.uwec.cs.jorandbe.assignment5;
import java.awt.HeadlessException;
import java.sql.*;
import javax.swing.*;
public class OracleDBConnection {
String username;
String host;
String password;
Driver theOracleDriver;
Connection myConn;
String sqlQuery;
ResultSet rs;
Statement stmt;
public OracleDBConnection() {
public OracleDBConnection(String hostn, String usern, String passw) {
this.host = hostn;
this.username = usern;
this.password = passw;
public void Open() {
try {
theOracleDriver = (Driver) (Class
.forName("oracle.jdbc.driver.OracleDriver")).newInstance();
DriverManager.registerDriver(theOracleDriver);
Connection myConn = DriverManager.getConnection(this.host,
this.username, this.password);
stmt = myConn.createStatement();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
public void Close() {
try {
if (rs != null)
rs.close();
if (myConn != null)
myConn.close();
if (stmt != null)
stmt.close();
} catch (SQLException e) {
e.printStackTrace();
public void setQueryString(String Query) {
sqlQuery = Query;
public void getQueryString(String Query) {
System.out.println("Current SqlQuery : " + sqlQuery);
//public String [][] executeSELECT() {
//rs = stmt.executeUpdate(sql);
// return rs;
public static void main(String[] args) {
OracleDBConnection Oracle1 = new OracleDBConnection("jdbc:oracle:thin:@stef.cs.uwec.edu:1521:csdev","Jorandbe","j8114");
//CLASS 2
package edu.uwec.cs.jorandbe.assignment5;
public class NFL_DDL {
     public static void main(String[] args) {
          OracleDBConnection Oracle1 = new OracleDBConnection("jdbc:oracle:thin:@stef.cs.uwec.edu:1521:csdev","Jorandbe","j8114");
Oracle1.Open();
Oracle1.Close();
public void createTables(Object Oracle1){
//Oracle1.Open();
can anyone tell me why Oracle1.Oen(); works in my main method
but in my create Table method as well??

Answer 1

public class NFL_DDL {
     public static void main(String[] args) {
          OracleDBConnection Oracle1 = new OracleDBConnection("jdbc:oracle:thin:@stef.cs.uwec.edu:1521:csdev","Jorandbe","j8114");
Oracle1.Open();
Oracle1.Close();
public void createTables(Object Oracle1){
//Oracle1.Open();
In the main up top, i can get the connection to open/ Oarcle1.Open works and it gives me no compile errors
but when i try to do the same thing in the createTables it gives me the evil red line under open and says
"The method Open() is undefined for the type Object"Where are you calling the createTables method ? How will the compiler know that it has to start off with the createTables ?
Open() is not a static method either ...?!?!?!?
what are you trying to do ?
