  題解

  參考課堂範例A262

  import java.util.ArrayList;
  import java.util.Scanner;
  
  public class OddPlusOne {
  
      public static void main(String[] args) {
          ArrayList<Integer> numbers = new ArrayList<>();
          Scanner scanner = new Scanner(System.in);
  
          int num;
          while (scanner.hasNextInt()) {  // 當下一筆輸入不是數字時 結束迴圈
              num = scanner.nextInt();
              if (num % 2 != 0)           // 接值後，判斷是否為奇數
                  num++;
              numbers.add(num);           // 處理完奇數後，加到ArrayList
          }
          scanner.close();
  
          // 用for-each依序印出ArrayList裡的東西
          for (int number : numbers) {
              System.out.print(number + " ");
          }
  
      }
  
  }
