这是一些我更愿意自己弄清楚的工作，所以如果可能的话，请你不要直接给出答案，但也许会指出正确的方向，说明为什么我从循环输出中收到错误以及为什么IF 语句未产生输出。
我必须允许用户输入“建议的最高员工工资”，然后从不同商店单位的文件中读取文本，以计算出每个商店单位的员工工资和员工总成本。
这是我必须阅读的文字

...continued up to 9 shop units.
这是我的代码:
public class Recursion {
public static void main(String[] args) {
// TODO Auto-generated method stub
int count =0;
int n = 1;
int t=0;
int triangularNumber =0;
while (n<Integer.MAX_VALUE)
{
t = isTriangularNumber(n,count,triangularNumber);
triangularNumber=0;
int starNumber= ((6*n)*(n-1)) + 1;
if (starNumber ==t)
{
System.out.println(t);
}
n++;
}
if (n==Integer.MAX_VALUE)
{
System.exit(0);
}
}
public static int isTriangularNumber(int n, int count, int triangularNumber)
{
triangularNumber =triangularNumber + (n-(n-count));
if (count<=n)
{
return isTriangularNumber(n,(count++), triangularNumber);
}
else return triangularNumber;
}
} shop unit 打印出来没问题，但是输出后就报错，if语句输出不出来，如下图:

Exception in thread "main" java.util.NoSuchElementException: No line found

知道是什么原因造成的吗？
最佳答案
以下几行给你一个错误:
Unitnum = inFile.nextLine();
Unitnum = inFile.nextLine();
您可以将它们包装在:
if (b < shopunits - 1) {
...
}
