Sql exception access denied

Question

well as the topic says I get an access denied exception. This is when I try to connect to the database
java.sql.SQLException: Access denied for user 'Java'@'localhost' (using password: YES)
I get the same problem when I try to connect with the root user.
this is the code I'm using, ignore the threads as they do not matter

I have tried the org driver too and I have tried (url, user, pass) and (url?user=user&password=pass)

Answer 1

well it's pretty weird, because I'm trying to make some kind of pattern with the install file I made, although... the install file works and looks like this
import java.io.*;
import java.net.*;
import java.sql.*;
public class install
    public static void main(String[] args) {
        try {
            // The newInstance() call is a work around for some
               //older java implementations
               //org.gjt.mm.mysql.Driver or com.mysql.jdbc.driver
            Class.forName("org.gjt.mm.mysql.Driver").newInstance();
        } catch (Exception ex) {
            ex.printStackTrace();
          try {
          System.out.println("write the user used to access the mysql database with Devil Chat");
          String user = Keyboard.readString(); //read mysql username from keyboard
          System.out.println("write the password used to access the mysql database with Devil Chat");
          String pass = Keyboard.readString(); //read password for user from keyboard
          Connection conn = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/mysql", user, pass);
          Statement stmt = conn.createStatement();
          stmt.executeUpdate("CREATE DATABASE IF NOT EXISTS Java");
          System.out.println("Database has been created");
          Connection con = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/Java", user, pass);
          Statement nstmt = con.createStatement();
          nstmt.executeUpdate("CREATE TABLE IF NOT EXISTS devilchat_users ("+
          "uid int NOT NULL AUTO_INCREMENT, PRIMARY KEY(uid), "
          +"username varchar(25), isadmin bool, spoken int, ip varchar(15))");
          System.out.println("Table has been created");
          con.close();
          conn.close();
               } catch (SQLException ex) {
    // handle any errors
    System.out.println("SQLException: " + ex.getMessage());
    System.out.println("SQLState: " + ex.getSQLState());
    System.out.println("VendorError: " + ex.getErrorCode() + "\n");
}
