意外的錯誤（全局變量/枚舉）

Question

我已經寫了下面的代碼段：

import java.util.Scanner; 

public class Congress { 
    public static int age; 
    public static int ctzn; 
    public static boolean eligibleForSenate() { 
     if (age >= 25 && ctzn >= 7) { 
     return true; 
     } else { 
     return false; 
     } 
    } 
    public static boolean eligibleForHouse() { 
    if (age >= 30 && ctzn >= 9) { 
     return true; 
    } else { 
     return false; 
    } 
    public static void main(String[] args) { 
    System.out.print("Enter age of candidate: "); 
    Scanner sc = new Scanner(System.in); 
    age = sc.nextInt(); 
    System.out.println(); 
    System.out.print("Enter years of U.S. Citizenship: "); 
    ctzn = sc.nextInt(); 
} 
} 
} 

這使我在主線錯誤。我相信這與全球變數有關。我該如何解決它？

有一個錯字:: 更改代碼如下::

import java.util.Scanner; 

    public class Congress { 
     public static int age; 
     public static int ctzn; 
     public static boolean eligibleForSenate() { 
      if (age >= 25 && ctzn >= 7) { 
      return true; 
      } else { 
      return false; 
      } 
     } 
     public static boolean eligibleForHouse() { 
     if (age >= 30 && ctzn >= 9) { 
      return true; 
     } else { 
      return false; 
     } 
     } 
     public static void main(String[] args) { 
     System.out.print("Enter age of candidate: "); 
     Scanner sc = new Scanner(System.in); 
     age = sc.nextInt(); 
     System.out.println(); 
     System.out.print("Enter years of U.S. Citizenship: "); 
     ctzn = sc.nextInt(); 
    } 

    }

你的括號不匹配，添加一個右括號}您main前，從中刪除的最後一行。
