Creating a JAVA database from code. Statement wont execute and create table?

Question

I'm not sure why my program isn't creating the table but I also need some ideas on how to fill the table with code like this once it's created? I need to add two more tables to this database too.

This is the error I'm getting :

java.sql.SQLSyntaxErrorException: Table/View 'PIZZASIZE' does not exist.
Caused by: ERROR 42X05: Table/View 'PIZZASIZE' does not exist.
Caused by: java.lang.RuntimeException: Exception in Application start method
Caused by: javafx.fxml.LoadException: file:/C:/Users/Allie/Documents/NetBeansProjects/Pizzeria_AllieBeckman/dist/run1674141987/Pizzeria_AllieBeckman.jar!/pizzeria_alliebeckman/FXMLDocument.fxml

This is the code that's supposed to create the table:

        // connect to the derby URL using the given username and password
        connect = DriverManager.getConnection("jdbc:derby://localhost:1527/pizzeria;create=true", connectProps);
        // current url for pre created database "jdbc:derby://localhost:1527/pizza"
        // if connection is successful print that it succeeded.
        System.out.println("database created");

        stmt = connect.createStatement();

        String sqlCreate = "CREATE TABLE PIZZASIZE "
            + "(id int NOT NULL, "
            + "size char(20) NOT NULL, "
            + "PRIMARY KEY (id))";

        stmt.execute(sqlCreate);

Depending on the IDE you are using you could manually create the table in a console without going through the trouble of writing it in code. Here are some examples of how you could get the information from the tables.

Connection conn = CreatingDerbyDJB.dbConnection();

            try{
                String query = "INSERT INTO  Items (Name,Color,ItemName,SchoolName, Description) VALUES(?,?,?,?, ?)";
                PreparedStatement pstmt = conn.prepareStatement(query);


                pstmt.execute();
                conn.close();
              }catch(Exception e)
            {
                  e.printStackTrace();
            }       }

Here is what the Connection class should look like: package main;

import java.sql.Connection;
import java.sql.DriverManager;

import javax.swing.JOptionPane;

public class CreatingDerbyDJB 
{
    public static final String DRIVER = "org.apache.derby.jdbc.EmbeddedDriver";
    public static final String JDBC_URL  = "jdbc:derby:LostAndFoundDB";
    public static Connection dbConnection()
    {
        try
        {
            Class.forName(DRIVER).newInstance();
            Connection c = DriverManager.getConnection(JDBC_URL);
            return c;
        }catch(Exception e)
        {
            JOptionPane.showMessageDialog(null, e);
            return null;
        }
    }
}
