Answer 1

避免將任何輸出格式放入原始數據中。 如果您養成了現在檢查的習慣，它將為您節省更多復雜程序的時間。 所以寫一下：

{"Montana", "Bitterroot ", "Western meadowlark"}, // removed space at end, too

然后當你打印出來時，你不會打印兩次標簽。 然后只需檢查索引號。 System.exit且不說，當你可以寫return時，請避免使用System.exit 。 祝好運！

Answer 2

// Print bird information
System.out.print( states[row][column+2]);
// Print Flower information
System.out.println(states[row][column+1] + "\n");

外觀看起來像

Enter a state: 
New York
Bird: Eastern bluebird Flower: Rose

Enter a state: 
New York
Bird: Eastern bluebird Flower: Rose

Enter a state: 
None
