Java: Repository Pattern
Answer
PreparedStatement is used for executing precompiled SQL queries.
A PreparedStatement in JDBC helps in executing SQL queries that are precompiled, reducing the risk of SQL injection and improving performance. For instance, in an e-commerce application, you might use a PreparedStatement to safely query a product by its ID: `SELECT * FROM products WHERE id =?`. The '?' is a placeholder that gets replaced by the actual ID when the query is executed.
