数据库表未在JavaFx中创建

Question

private DatabaseHandler() {
    createConnection();
    COUNTRYNAME();
    STATETBL();
}

void createConnection() {
    try {
            Class.forName("org.postgresql.Driver").newInstance();
            conn = DriverManager.getConnection(DB_URL,"postgres", "root");
        } catch (Exception e) {
            e.printStackTrace();
        }
}

国家/地区表

void COUNTRYNAME() {
    String TABLE_NAME = "COUNTRY_TBL";
    try {
        stmt = conn.createStatement();
        DatabaseMetaData dbm = conn.getMetaData();
        ResultSet tables = dbm.getTables(null, null, TABLE_NAME.toUpperCase(), null);
        if (tables.next()) {
          System.out.println("Table " + TABLE_NAME + "already exists. Ready for go!");
        } else {
            stmt.execute("CREATE TABLE " + TABLE_NAME + "(id SERIAL PRIMARY KEY,\n"
                    + " COUNTRYname varchar(20),\n"
                    + " COUNTRY2CHAR varchar(50),\n"
                    + " DESCR varchar(50),\n"
                    + " DESCRSHORT varchar(50)"+")");
        }
    } catch (SQLException e) {
        System.err.println(e.getMessage() + " --- setupDatabase");
    } finally {
    }
}

州表

void STATETBL() {
    String TABLE_NAME = "STATE_TBL";
    try {
        stmt = conn.createStatement();
        DatabaseMetaData dbm = conn.getMetaData();
        ResultSet tables = dbm.getTables(null, null, TABLE_NAME.toUpperCase(), null);
        if (tables.next()) {
            System.out.println("Table " + TABLE_NAME + "already exists. Ready for go!");
        } else {
            stmt.execute("CREATE TABLE " + TABLE_NAME + "("
                    + " id SERIAL PRIMARY KEY,\n"
                    + " COUNTRYid varchar(20),\n"
                    + " STATE varchar(50),\n"
                    + " DESCR varchar(50),\n"
                    + " DESCRSHORT varchar(50),\n"
                    + " NUMERIC_CD varchar(50),\n"
                    + " FOREIGN KEY (COUNTRYid) REFERENCES COUNTRY_TBL(id)"+")");
        }
    } catch (SQLException e) {
        System.err.println(e.getMessage() + " --- setupDatabase");
    } finally {
    }
}

当我执行上面的代码时，CountryName表在我的数据库中生成，但我的State表没有生成
