What are the five steps performed by a JDBC execution?

  1. Load driver: Load JDBC driver using the Class.forName() method.
  2. Establish connection: Use the DriverManager.getConnection() method to establish a connection with the database.
  3. Create SQL statement: Generate the SQL statement to be executed, which can be a query, insert, update, or delete.
  4. Execute SQL statements: Using Statement or PreparedStatement objects to execute SQL statements, you can use the executeQuery() method for querying operations and the executeUpdate() method for inserting, updating, or deleting operations.
  5. Result processing: Depending on the different SQL statements, the execution results can be obtained through the ResultSet object to retrieve query results, or by checking the number of affected rows after execution. Finally, close the connection and release resources.
