Answer
They separate SQL logic from data. Frame the concept in practical terms so you can explain it during interview discussion.
PreparedStatements in Java prevent SQL Injection by precompiling the SQL query and using placeholders for parameters. This ensures user input is treated as data, not executable code. For example, `PreparedStatement pstmt = connection.prepareStatement("SELECT * FROM users WHERE username =?")` safely inserts a username without altering the SQL structure.
