Внедрение того же кода разными способами

Question

Я написал следующий код, однако попытался выяснить, как его переписать, включив параметры и логические значения, если это возможно, когда основной метод запрашивает ввод пользователя, а затем вызывает методы для получения результата:

import java.util.*; 

class Congress 
{ 
    public static void main (String [] args) 
    { 
      int age, citizen, i, r; 
      citizen = 0; 
      i = 0; 
      r = 0; 
      age = -1; 
      Scanner keyboard = new Scanner(System.in); 
      System.out.println ("CONGRESS ELIGIBILITY"); 
      for (age = -1; age < 0; r++) 
      { 
        System.out.println(); 
        System.out.print ("Enter age of candidate: "); 
        age = keyboard.nextInt(); 
        System.out.print ("Enter years of US citizenship: "); 
        citizen = keyboard.nextInt(); 
        if (age <= 0) 
        { 
         System.out.print ("Please enter a proper age. "); 
        } 
      } 
      if (age >= 25 && citizen >= 7) { 
        i++; 
      } 
      if (age >= 30 && citizen >= 9) { 
        i++; 
      } 
      if (i == 0) { 
      System.out.println ("The candidate is not eligible for election to either the House of Representatives or the Senate."); 
      } 
      if (i == 1) { 
        System.out.println ("The candidate is eligible for election to the House of Representatives but is not eligible for election to the Senate."); 
      } 
      if (i == 2) { 
        System.out.println ("The candidate is eligible for election to both the House of Representatives and the Senate."); 
      } 
    } 

}
