Answer
Using concatenated strings for SQL queries; use prepared statements instead.
SQL Injection is a vulnerability that allows attackers to manipulate SQL queries by injecting malicious input. This often occurs when queries are constructed using string concatenation. Prepared statements in Java use placeholders for parameters, safely handling input values and preventing injection. For example, in a login feature, use `PreparedStatement` to safely incorporate user input into a SQL query.
