Thread: How do i user a Scanner that was imported in another Class? (student, beginner)

Hi, first year student here, first post!

I've attached the diagram of the program in question, question is: in the CharacterHolder class I am required to get input, but the Scanner is the PokemonBattler class.
(specifically, input needs to happen in the UserPicksCharacterFromHand() method)

We are required to use the Scanner imported in the PokemonBatter Class, but i cant find any specific examples in my notes on how to do this.

the program is complete and currently working with an instance of Scanner being imported from inside the CharacterHolder class.

I hope this is enough information.

Yes! thank you!

all i had to do was change:

int number = in.nextInt();

to:

int number = PokemonBattler.in.nextInt();

Sorry for not posting code in the first place, but thanks for the reply!

Thank you for the reply again, I'm not sure if I understand what you mean though? Could you give me an example of what you are describing? I can post more code, but I'm not sure what would help.

Currently what is happening is:

The class with the main method contains -

import java.util.Scanner;
public class PokemonBattler
{
public static Scanner in = new Scanner(System.in);
}

and the class calling it is doing something like -

System.out.print("\n\t\tYou have the following pokemon:\n ");
        for (int i = 0; i < characters.length; i++)
        {
            System.out.print("\n" + (i + 1) + ". " + characters[i].toString());
        }
 
        do
        {
            System.out.print("\n\n\tEnter your choice: ");
            boolean isInt = PokemonBattler.in.hasNextInt();
