Create Tables on Very Furst Run of the Application

Question

Hi,
I'm trying to create a derby(Java DB) database and its tables on the very first run of the application, but when I run second time, obviously it throws an exception of TABLE/VIEW already exists.
So, once the database and its tables are created, how do I check for the second time so that it does not try to create it again.
heres the code
            System.setProperty("derby.system.home", System.getProperty("user.dir"));
            Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();
            Global.con = DriverManager.getConnection("jdbc:derby:emails;create=true");
            Statement stat = Global.con.createStatement();
            stat.executeUpdate("CREATE TABLE emails(" +
                    "email VARCHAR(100) DEFAULT ''," +
                    "category VARCHAR(80) DEFAULT ''," +
                    "status VARCHAR(30) DEFAULT ''," +
                    "website VARCHAR(100) DEFAULT ''" +
            stat.executeUpdate("INSERT INTO emails(email, status, website) VALUES('[email protected]', 'unsubscribed', 'alsharia.org')");
            ResultSet rs = stat.executeQuery("Select * from emails");
            while (rs.next()) {
                System.out.println(rs.getString("email"));
                System.out.println(rs.getString("status"));
                System.out.println(rs.getString("website"));
            }

Great. Heres the complete code with the solution.
        try {
            System.setProperty("derby.system.home", System.getProperty("user.dir"));
            Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();
            Global.con = DriverManager.getConnection("jdbc:derby:emails;create=true");
            metaData = Global.con.getMetaData();
            rs = metaData.getTables(null, null, "%", null);
            while (rs.next()) {
                if (rs.getString(3).equals("EMAILS")) {
                    System.out.println("database found");
                    databaseFound = true;
            if (databaseFound == false) {
                System.out.println("creating database");
                stat = Global.con.createStatement();
                stat.executeUpdate("CREATE TABLE emails(" +
                        "email VARCHAR(100) DEFAULT ''," +
                        "category VARCHAR(80) DEFAULT ''," +
                        "status VARCHAR(30) DEFAULT ''," +
                        "website VARCHAR(100) DEFAULT ''" +
                stat.executeUpdate("INSERT INTO emails(email, category, status, website) VALUES('[email protected]', 'Education', 'subscribed', 'website.org')");
            rs = stat.executeQuery("Select * from emails");
            while (rs.next()) {
                System.out.println(rs.getString("email"));
                System.out.println(rs.getString("status"));
                System.out.println(rs.getString("website"));
        } catch (Exception e) {
            e.printStackTrace();
        }
