    Default Declaring an object with the static modifier

    Hello!
    I am quite new to programming in Java so I have difficulty trying to grasp why things work the way they do and such. This question is about the use of static for the declaration of an object. I attach the code below:
    public class Main {
     
        private static Scanner scanner = new Scanner(System.in);
     
        public static void main(String[] args) {
            System.out.println("Type in:");
            int count = scanner.nextInt();
            scanner.nextLine();
    }
    Can someone explain to me why it is done that way and the advantages? Thanks a lot.

    Regards.

    Default Re: Declaring an object with the static modifier

    the static modifier means a variable belongs to the class and can be referenced and used without an instance of the class.
    Code inside of a static method can only access variables outside of the method that are static.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
