用vc建立windows32api程序，编译时显示不能打开头文件windows.h 怎么弄？

Posted 2023-05-07

自己找到include 文件夹 新建个 txt文件 名字改成 windows.h
然后复制 粘贴进去保存

运行给定程序时显示编译错误

我刚刚开始在Codeforce上练习竞争性编程。在解决问题时遇到了一个问题。它显示了编译时错误

import java.util.*;
public class A71

    public static void main(String args[])
    
        Scanner sc=new Scanner(System.in);
        int n ;
        n=sc.nextInt();
        String a[] = new String[n];
        for(int i=0;i<n;i++)
        
            a[i]=sc.nextLine();
        
        for(int i=0;i<n;i++)
        
            int l=a[i].length();
            System.out.println(a[i].charAt(0)+""+(l-2)+""+a[i].charAt(l-1));
        
    

显示的错误在下面

java.lang.StringIndexOutOfBoundsException: String index out of range: 0
    at java.base/java.lang.StringLatin1.charAt(StringLatin1.java:47)
    at java.base/java.lang.String.charAt(String.java:693)
    at A71.main(A71.java:17)

Runtime error: exit code is 11

答案

如Stultuske在评论中指出，由于访问空字符串，您会收到此错误。尝试在循环中将sc.nextLine（）替换为sc.next（）
