如何修復錯誤ArrayIndexOutOfBoundsException：索引1超出長度1的范圍？

Question

我不知道問題出在哪里 我正在嘗試打印客戶詳細信息 我已經嘗試更改變量但它不起作用 問題似乎是什么？ 我已經嘗試了很多東西，但仍然無法修復錯誤。

導入 java.util.Scanner；

公共 class 主要 {

public static void main(String args[]) throws Exception {

    Scanner sc = new Scanner(System.in);
    String s1[] = sc.nextLine().split(" ");

    String s2[] = sc.nextLine().split(" ");

    String s3[] = sc.nextLine().split(" ");

    int id = Integer.parseInt(s1[0]);
    String name = s1[1];

    String area = s2[0];

    String city = s2[1];

    int day = Integer.parseInt(s3[0]);
    int month = Integer.parseInt(s3[1]);

    int year = Integer.parseInt(s3[2]);

    SimpleDate date = new SimpleDate(day, month, year);

    Customer c = new Customer(id, name, add, date);

    System.out.print(c);

請提供更多細節。
究竟是哪條線導致了這個問題？
您也可以刪除除公共 static void 之外的所有代碼，因為它從未被調用
可以給出錯誤的兩個地方是這兩個：

String name = s1[1];
String city = s2[1];

問題是你給他們的輸入。 s1[1]和s2[2]指向輸入行的第二個單詞（數組從索引 0 開始）。 因此，要解決您的錯誤，您的輸入必須如下所示：

name name
area
city city

而且您可能只是以錯誤的方式編寫輸入。
或者，也許您打算這樣寫：

String name = s1[0];
String city = s2[0];

在必須在stackoverflow上發布問題之前，有很多地方解釋了索引越界錯誤。
