I completed the task but still unsure

It doesn't matter in which order you read values from keyboard, for example you can read some value first, save it in some variable, and then print it very last.

public static void main(String[] args) throws Exception {
    BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
    String value1 = reader.readLine();
    String value2 = reader.readLine();
    String value3 = reader.readLine();

    System.out.println(value3);
    System.out.println(value1);
    System.out.println(value2);
    System.out.println(value1 + value3 + value2);
}

But! The condition says: Enter the number and name from the keyboard And then: The order in which the data is input matters a lot. So, think about it.

When you make a "scanner" you should only make it once! when you make it it does not call nor start itself, the "typing input box" would appear when you use something like NAME.nextInt() that is the place which call the scanner and makes you type text into a box.
