不断要求更多投入

Question

我已经对此进行了多次测试，但是我不知道出了什么问题。 每次我编译时，它都会按预期的那样要求范围，但是在设置upperRange之后，它会继续要求更多输入，而从未进入程序的其余部分。
这是最重要的部分：

   Scanner in = new Scanner(System.in);

    System.out.printf("%30s%n","Range of Years");
    System.out.println("Enter the lowest year of the range:");
    int lowerRange = in.nextInt();
    System.out.println("Enter the highest year of the range:");
    int upperRange = in.nextInt();

    if(lowerRange>upperRange){
    System.out.println("Please make sure the upper range is later than the lower range.");
    System.out.println("Enter the lowest year of the range:");
    lowerRange = in.nextInt();
    System.out.println("Enter the highest year of the range:");
    upperRange = in.nextInt();
}
   else if(lowerRange<1995){
    System.out.println("Sorry, no data on hurricanes from before 1995. Please try 1995 or later.");
    System.out.println("Enter the lowest year of the range:");
    lowerRange = in.nextInt();
    System.out.println("Enter the highest year of the range:");
    upperRange = in.nextInt();
}
  else if(upperRange>2015){
    System.out.println("Sorry, no data on hurricanes from after 2015. Please try 2015 or earlier.");
    System.out.println("Enter the highest year of the range:");
    upperRange = in.nextInt();
}

    String token = "";
    File hurricaneData = new File("hurricanedata.txt");
    Scanner inFile = new Scanner(hurricaneData);


int counter = 0;
while(inFile.hasNextLine()){
    counter++;
    inFile.hasNextLine();
}
