问题描述
首先，我想说的是，我在编程方面是个新手，所以这个问题看似微不足道，但我无法弄清楚。 每当我尝试提交此问题的答案时，即使输出似乎是正确的，我也会不断遇到运行时错误
这是代码：
import java.util.Scanner;
public class PrimeGenerator{
public static void main(String[] args){
Scanner userInput = new Scanner(System.in);
String wordLength = new String();
String output = new String();
int linenumber = 1;
int i = userInput.nextInt();
while(i>=1||i<=1000){
int wordlength;
String dataset = userInput.next();
String dataset2 = userInput.next();
boolean haslowercase = !dataset2.equals(dataset2.toLowerCase());
if(!haslowercase){
break;
}else{
wordLength = String.valueOf(dataset);
int dataset2length = dataset2.length();
wordlength = Integer.parseInt(wordLength);
if(wordlength>80){
break;
}
else{
if(wordlength>dataset2length){
break;
}else{
output = dataset2.substring(0,wordlength-1)+ dataset2.substring(wordlength,dataset2.length());
System.out.println(linenumber+" "+output);
linenumber++;
}
}
}
}
}
}
