Question

I need to guess from user (number as string) and convert that into int array. If user put "789" array[0] should be 7. However, since two methods are in different classes and I cannot use constructors (except for main), I have no idea how I can do this.

Code should be something like this.

import java.util.Scanner;

Class Guess {

Scanner sc= new Scanner(System.in);

public String askGuess(){

String guess = sc.nextLine();

return guess;

}

Class convert is just showing the concept.

Class Convert {

public int[] convert(//Needs to be String)
   {
       String converted = //import guess somehow
       int[] conArray = new int [convert.length()];

       for(int i = 0; i < converted.length(); i++)
       {
           conArray [i] = converted.charAt(i)
       }

       return conArray;
   }

}

Class Main {

Guess guessGet = new Guess();

System.out.printf("Guess? ");

guessGet .askForGuess();

}

ANSWER:-

import java.util.*;
class Guess{
   Scanner sc = new Scanner(System.in);
   public String askGuess(){
       String guess = sc.nextLine();
       return guess;
   }
}
class Convert{
   public int[] convert(String s){
       String converted = s;
       int[] conArray = new int[converted.length()];
       for(int i = 0;i<converted.length();i++){
           // parseInt() expects string as argument, but converted.charAt(i) is character,
           // so we need to convert it to string
           conArray[i] = Integer.parseInt(String.valueOf(converted.charAt(i)));
       }
       return conArray;
   }
}
class Main{
   public static void main(String[] args) {
       Guess guessGet = new Guess();
       System.out.print("Guess? ");
       String numStr = guessGet.askGuess();
       Convert con = new Convert();
       int[] numArray = con.convert(numStr);

// Print numArray
       for(int i = 0;i<numArray.length;i++){
           System.out.print(numArray[i]+" ");
       }
   }
}
