Okay, let's dive deep into the differences between `Statement` and `PreparedStatement` in JDBC (Java Database Connectivity). We'll cover their purposes, syntax, performance implications, security aspects, and provide comprehensive code examples to illustrate their usage.

*Understanding JDBC and SQL Injection*

Before we get into the specifics, let's quickly recap JDBC and the importance of writing secure SQL code.

*JDBC (Java Database Connectivity):* A Java API that allows you to connect to a database, execute SQL queries, and retrieve results. It's the standard way for Java applications to interact with relational databases.

*SQL Injection:* A security vulnerability where attackers can inject malicious SQL code into your queries, potentially gaining unauthorized access to your data, modifying data, or even executing arbitrary commands on the database server.

*1. Statement*

The `Statement` interface is the most basic way to execute SQL queries using JDBC. You create a `Statement` object, build your SQL query as a string, and then execute the query.

*Purpose:*

Executes static SQL queries. "Static" means the query structure is fixed at compile time. You directly concatenate values into the SQL string.

*Syntax:*



*Explanation:*

1. *`DriverManager.getConnection()`:* Establishes a connection to the database using the provided URL, username, and password. Replace the placeholder values with your actual database connection details.

2. *`connection.createStatement()`:* Creates a `Statement` object from the connection.

3. *`statement.executeUpdate(sql)`:* Executes SQL statements that modify the database (e.g., `CREATE TABLE`, `INSERT`, `UPDATE`, `DELETE`). It returns the number of rows affected by the statement.

4. *`statement.executeQuery(sql)`:* Executes SQL `SELECT` queries. It returns a `ResultSet` object, which contains the data retrieved from the database.

5. *`ResultSet` Iteration:* The `ResultSet` is ite ...
