Please describe\n\nYes, for issue #100, support JDBC database operations.\n\n### Describe the solution you'd like\n\nThe generated `analysis.json` must be able to capture JDBC including operations using `Connection`, `Statement`, `PreparedStatement`, and `ResultSet`.\n\n#### 1. If the callsite ReceiverType is **`Statement`**, **`PreparedStatement`**, and **`CallableStatement`**\nWe want to look for the following methods:\n\n**Class** | **Method** | **Description** | **CRUD Operation**\n-- | -- | -- | --\n**`Statement`** | `addBatch(String sql)` | Adds an SQL command to batch. | ANY (C/U/D)\n  | `execute(String sql)` | Executes an SQL statement that may return multiple results. | ANY (C/R/U/D)\n  | `executeBatch()` | Executes a batch of SQL commands. | ANY (C/U/D)\n  | `executeLargeBatch()` | Executes a large batch of SQL commands. | ANY (C/U/D)\n  | `executeLargeUpdate(String sql)` | Executes `INSERT`, `UPDATE`, `DELETE`, or DDL statements. | C/U/D\n  | `executeQuery(String sql)` | Executes a `SELECT` query and returns a ResultSet. | READ\n  | `executeUpdate(String sql)` | Executes `INSERT`, `UPDATE`, `DELETE`, or DDL statements. | C/U/D\n  | `getResultSet()` | Retrieves the current ResultSet. | READ\n  | `getGeneratedKeys()` | Retrieves auto-generated keys from an `INSERT` operation. | READ (post-C)\n  | `getUpdateCount()` | Returns the number of rows affected by an `UPDATE`, `INSERT`, or `DELETE`. | READ (post-U/D)\n**`PreparedStatement`** | addBatch() | Adds the current parameters to the batch of commands. | ANY (C/U/D)\n  | `execute()` | Executes any SQL statement. | ANY (C/R/U/D)\n  | `executeLargeUpdate()` | Executes `INSERT`, `UPDATE`, `DELETE`, or DDL statements. | C/U/D\n  | `executeQuery()` | Executes a `SELECT` query and returns a ResultSet. | READ\n  | `executeUpdate()` |

| READ\n**`CallableStatement`** | execute() | Executes a stored procedure. | ANY (C/R/U/D)\n  | `executeQuery()` | Executes a stored procedure that returns a ResultSet. | READ\n  | `executeUpdate()` | Executes a stored procedure that performs `INSERT`, `UPDATE`, or `DELETE`. | C/U/D\n  | `getXxx(int parameterIndex)` | Retrieves output parameters from the stored procedure (e.g., `getInt`,
