Чтобы проверить, существует ли таблица в SQLite с использованием Java, вы можете использовать следующие методы:

1. Метод 1: использование необработанного SQL-запроса

   String tableName = "your_table_name";
   String query = "SELECT name FROM sqlite_master WHERE type='table' AND name='" + tableName + "'";
   try (Connection connection = DriverManager.getConnection("jdbc:sqlite:your_database.db");
    Statement statement = connection.createStatement();
    ResultSet resultSet = statement.executeQuery(query)) {
   if (resultSet.next()) {
       // Table exists
       System.out.println("Table exists!");
   } else {
       // Table does not exist
       System.out.println("Table does not exist!");
   }
   } catch (SQLException e) {
   e.printStackTrace();
   }

2. Метод 2: использование DatabaseMetaData

   String tableName = "your_table_name";
   try (Connection connection = DriverManager.getConnection("jdbc:sqlite:your_database.db")) {
   DatabaseMetaData metaData = connection.getMetaData();
   try (ResultSet tables = metaData.getTables(null, null, tableName, null)) {
       if (tables.next()) {
           // Table exists
           System.out.println("Table exists!");
       } else {
           // Table does not exist
           System.out.println("Table does not exist!");
       }
   }
   } catch (SQLException e) {
   e.printStackTrace();
   }

3. Метод 3: использование оператора PRAGMA, специфичного для SQLite

   String tableName = "your_table_name";
   String pragmaQuery = "PRAGMA table_info(" + tableName + ")";
   try (Connection connection = DriverManager.getConnection("jdbc:sqlite:your_database.db");
    Statement statement = connection.createStatement();
    ResultSet resultSet = statement.executeQuery(pragmaQuery)) {
   if (resultSet.next()) {
       // Table exists
       System.out.println("Table exists!");
   } else {
       // Table does not exist
       System.out.println("Table does not exist!");
   }
   } catch (SQLException e) {
   e.printStackTrace();
   }
