What is the significance of using a PreparedStatement over a Statement in Java's JDBC?Question 14Answera.Improved performance and securityb.Simplicity and ease of usec.Enhanced database schemad.Compatibility with NoSQL databases

The significance of using a PreparedStatement over a Statement in Java's JDBC is primarily for improved performance and security.

Here's why:

1. Improved Performance: PreparedStatement is faster than Statement in Java's JDBC because it is precompiled. This means that when it is executed multiple times, the database software reuses the previously prepared and optimized statement, leading to improved performance.

2. Enhanced Security: PreparedStatement helps prevent SQL Injection attacks. This is because values are passed as parameters and are always treated as literals and not part of SQL command. By contrast, with Statement, concatenating strings to form SQL commands can lead to SQL Injection attacks if not handled properly.

So, the correct answer is a. Improved performance and security.

The significance of using a PreparedStatement over a Statement in Java's JDBC is primarily for improved performance and security.

Here's why:

1. Improved Performance: PreparedStatement is faster than Statement because it is precompiled. This means that when it is executed, the DBMS can just run the PreparedStatement's SQL statement without having to compile it first.

2. Security: PreparedStatement helps prevent SQL injection attacks. This is because parameters are automatically escaped before the statement is executed.

So, the correct answer to your question is a. Improved performance and security.
