Question

I wrote two java classes. One is main and other one is getter and setter. I brought methods from Digit class to Main class to print result. However, for some reason, only welcome print statement got printed and others got ignored. On the output screen, only welcome statement appear. nDigit should be input from user.

import java.util.Scanner;

public class Main
{

   public static void main(String[] args)
   {
       Digit digitGet = new Digit();
      
       System.out.println("Welcome ");
      
       int eDigit = 0;
       digitGet .setDigits(eDigit);
       eDigit= digitGet .getDigit();
      
       System.out.println("Enter the number of digits to use: " + nDigit);

   }

}

import java.util.Scanner;

public class Digit
{
  
   private int digit;
   Scanner sc= new Scanner(System.in);

public int getDigit()
{
       return this.digit;
}

public void setDigits(int i)
   {
       i= keyboard.nextInt();
       this.digit= i;
   }

}

import java.util.Scanner;

public class Main {

   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
      
       Digit digitGet = new Digit();
       System.out.println("Welcome ");
       // you need to read here only
       System.out.println("Enter digit: ");
       int eDigit = sc.nextInt();
       digitGet.setDigits(eDigit);
       eDigit = digitGet.getDigit();
       System.out.println("Enter the number of digits to use: " + eDigit);

   }

}

class Digit {

   private int digit;

   public int getDigit() {
       return this.digit;
   }

   public void setDigits(int i) {
      
   // i= keyboard.nextInt(); because of this line it is waiting here so that is the
       //reason your not getting anything
       this.digit = i;
   }

}
