Prepared statements separate SQL code from data, preventing malicious input from altering query execution.
Prepared statements in Java are used to safely insert user input into SQL queries. By pre-compiling the SQL query and using placeholders for parameters, the input is treated as data, not executable code. This prevents attackers from injecting malicious SQL. For example, in a Java e-commerce site, using a `PreparedStatement` ensures that user-submitted search queries cannot execute harmful SQL commands against the database.
