Question

当我尝试测试文件读取时，出现堆栈溢出错误。我知道为什么会这样，但我不知道为什么它会在我的程序中发生以及如何解决它。这是我的主要，加载方法，显示方法和文件：

public static void main(String[] args) 
{
    try 
    {
        loadEmployeesFromFile("employees.txt");
        displayEmployees();    
    }catch (FileNotFoundException e) 
    {
        System.err.println("File error: " + e.getMessage());
    }catch (IOException e) 
    {
        System.err.println("IO error: " + e.getMessage());
    }
}

private static void loadEmployeesFromFile(String filename) throws IOException {
    try (Scanner fin = new Scanner(new File(filename));) 
    {
        String employeeRecord;
        String fields[];

        while (fin.hasNext()) 
        {
            employeeRecord = fin.nextLine();
            fields = employeeRecord.split(",");

            switch (fields[0]) {
                case "F":
                    staff[numberOfRecords] = new FullTime(Double.parseDouble(fields[1]), fields[2], fields[3]);
                    break;
                case "P":
                    staff[numberOfRecords] = new PartTime(Double.parseDouble(fields[2]), Double.parseDouble(fields[3]), fields[4], fields[5]);
                    break;    
                case "I":
                    staff[numberOfRecords] = new Intern(fields[1], fields[2]);
                    break;
            }
            numberOfRecords++;
        }// end while
    }
}

private static void displayEmployees() 
{
    for (int i = 0; i <= numberOfRecords - 1; i++) 
    {
        System.out.println(staff[i]);
    }
}

I，i1First，i1Last

您已检查bundles.Add(new ScriptBundle("~/bundles/jquery").Include( "~/Scripts/jquery-{version}.js")); bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include( "~/Scripts/jquery.validate*", "~/Scripts/jquery.unobtrusive-ajax.min.js"));但尚未执行while(fin.hasNext())，因此迭代器永远不会前进尝试做

fin.next()

希望这有帮助！

祝你好运！
