问如何在Java中对用户从扫描仪输入的时间进行计时，并根据特定的时间间隔将输入放入一个类别中？

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);  // Create a Scanner object
        
        System.out.println("What is the powerhouse of the cell?"); // First question

        long startTime = System.currentTimeMillis(); // Save start time
        String answer = scanner.nextLine();  // Read user input
        long endTime = System.currentTimeMillis(); // Save time after enter
        long questionTime = (endTime - startTime) / 1000; // Calculate difference and convert to seconds

        if (answer.equals("Mitochondria")) { // Check if answer is correct and print output
            System.out.println("The answer is correct, and user took " + questionTime + " seconds to press enter");
        } else {
            System.out.println("The answer is wrong, and user took " + questionTime + " seconds to press enter");
        }
    }
}

What is the powerhouse of the cell?
Mitochondria
The answer is correct, and user took 3 seconds to press enter
