Scanner in = new Scanner(System.in); int N = in.nextInt();

As I understand it, the first line creates an in instance of the Scanner class (the default constructor is used). And in the second integer variable N using the nextInt() method, which reads the first number entered from the keyboard, the value we entered is assigned. Did I understand this correctly? And what in the first case does the entry in brackets in the first line mean?

    The nextInt() method reads an integer value from the input stream. In this case, this value is stored in the variable N

    And what in the first case does the entry in brackets in the first line mean?

    To create a Scanner object, you must specify for which particular input stream it is created.

     Scanner in = new Scanner(System.in);

    In this particular case, a Scanner object is created for the standard input stream (keyboard).
