我已经实现了搜索功能以获取客户的详细信息，但是当我选择搜索的项目时，它给我一个错误
java.lang.ArrayIndexOutOfBoundsException: length=1; index=1
依此类推
这是我使用Json搜索客户详细信息并存储在数组中的代码，但是当我搜索数据并选择它时，出现上述错误。请帮帮我。谢谢

答案 0 :(得分：0)
错误ArrayIndexOutOfBoundsException：length = 1; index = 1表示索引1处的数组无效；换句话说，您正在尝试访问只有一个元素的数组的第二个元素。
下面的代码将给出类似的错误：
public class ReplicateError {
public static void main(String args[]) {
// reproducing java.lang.ArrayIndexOutOfBoundsException : 1 error
String[] clients = {"John"};
String client = clients[1];
// this will throw java.lang.ArrayIndexOutOfBoundsException : 1
System.out.println(client);
}
}
我建议您进行装订检查：
if (args.length < 2) {
System.err.println("Not enough arguments received.");
return;
}
