What is the difference between Statement and PreparedStatement in JDBC?

In JDBC, both Statement and PreparedStatement are used to execute SQL queries against a database. However, there are some key differences between them:

• Performance: PreparedStatement is precompiled at the time of creation, which makes it faster than Statement for executing multiple similar queries.
• Security: PreparedStatement is more secure as it provides protection against SQL injection attacks by automatically escaping special characters in the query parameters.
• Caching: Some JDBC drivers cache PreparedStatement objects, which can further improve performance in certain scenarios.
• Parameterized queries: PreparedStatement supports parameterized queries, allowing for the easier and safer passing of parameters into the query.

Overall, PreparedStatement is recommended for most situations due to its performance, security, and ease of use when working with SQL queries in JDBC.
