Question

我写了以下代码：

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();
 }
}
}

它在主线上给我一个错误。我认为它与全局变量有关。我该如何解决？

有一个拼写错误:: 更改代码如下::

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();
     }

    }

您的大括号不匹配，请在}之前添加一个右大括号main，并从最后一行中删除一个大括号。

意外错误（全局变量/枚举）
