Answer:
Answer Choice A
Step-by-step explanation:
A. Java code
Java is a versatile programming language that is commonly used for creating applications, including user account management systems. It provides features for file handling, making it suitable for tasks like storing and updating user details in a file. Additionally, Java is known for its platform independence, making it a good choice for various applications.
Here is a simplified example of what the Java code might look like for a basic user account management system:
import java.io.FileWriter;
import java.io.IOException;
import java.util.Scanner;
public class UserManagementSystem {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("User Account Management System");
// Get user input for creating or resetting a user
System.out.print("Enter 'create' to create a new user, or 'reset' to reset a user password: ");
String action = scanner.nextLine();
if (action.equals("create")) {
createUser();
} else if (action.equals("reset")) {
resetPassword();
} else {
System.out.println("Invalid action. Please enter 'create' or 'reset'.");
}
scanner.close();
}
private static void createUser() {
// Logic for creating a new user and updating the file
// ...
System.out.println("User created successfully!");
}
private static void resetPassword() {
// Logic for resetting a user password and updating the file
// ...
System.out.println("User password reset successfully!");
}
}
This is just a simple example to illustrate the idea. The actual implementation would depend on the specific requirements and the complexity of the user account management system.
