Answer
Use PreparedStatement to insert parameter values safely.
PreparedStatements are used to safely include user input into SQL queries, preventing SQL injection attacks. They allow you to define a query with placeholders and bind values to those placeholders. For example, to fetch a customer by ID: 'SELECT * FROM customers WHERE id =?'. Bind the ID using 'preparedStatement.setInt(1, customerId);'.
