如何修复错误ArrayIndexOutOfBoundsException：索引1超出长度1的范围？

Question

我不知道问题出在哪里 我正在尝试打印客户详细信息 我已经尝试更改变量但它不起作用 问题似乎是什么？ 我已经尝试了很多东西，但仍然无法修复错误。

导入 java.util.Scanner；

公共 class 主要 {

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

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

    String area = s2[0];

    String city = s2[1];

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

请提供更多细节。
究竟是哪条线导致了这个问题？
您也可以删除除公共 static void 之外的所有代码，因为它从未被调用
可以给出错误的两个地方是这两个：

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

问题是你给他们的输入。 s1[1]和s2[2]指向输入行的第二个单词（数组从索引 0 开始）。 因此，要解决您的错误，您的输入必须如下所示：

name name
area
city city

而且您可能只是以错误的方式编写输入。
或者，也许您打算这样写：

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

在必须在stackoverflow上发布问题之前，有很多地方解释了索引越界错误。
