Question

我有这段代码：

ArrayList<Employee> ArrEmployee = new ArrayList<Employee>(); //  array for employee objects

        try {
            Scanner txtIn = new Scanner(new File("/Users/PatrickBui/Documents/workspace/COMP 249 - Assignment 3/src/payroll.txt"));

        for (int i = 0; i < ArrEmployee.size(); ++i){   
            while (txtIn.hasNext()) { // looping through the payroll.txt file and creating Employee objects from its data
                try{
                long EmployeeNumber = txtIn.nextLong();
                String EmployeeName = txtIn.next();
                String LastName = txtIn.next();
                double HoursWorked = txtIn.nextDouble();
                double HourlyWage = txtIn.nextDouble();
                    if (ArrEmployee.get(i).getHourlyWage() > 10.35){ 
                    throw new InputMismatchException(); // throws exception if the hourly wage is less than 10.35$
                }
                    ArrEmployee.add(new Employee(EmployeeNumber,EmployeeName,LastName,HoursWorked,HourlyWage));

                }
                catch (InputMismatchException n) { // catching long,strings and doubles in the payroll.txt that aren't valid
                    PrintWriter txtOut = new PrintWriter("/Users/PatrickBui/Documents/workspace/COMP 249 - Assignment 3/src/payrollError.txt");
                    txtOut.println(Employee.EmployeeNumber + " " + Employee.EmployeeName + " " + Employee.LastName + " " + Employee.HoursWorked + " " + Employee.HourlyWage);
                    txtOut.close();
                      }
            }
        }

我试图找出一种可以看到的方法，因为我的catch (InputMismatchException n)将变量EmployeeNumber，[...]，HourlyWage写入名为payrollError.txt的文件

我已经尝试了很多次但是payrollError.txt文件没有任何问题......我的代码肯定有问题，但我似乎无法弄清楚

我会评论，但声誉不让我......

以下代码适用于我：

public class Test {

    public static void main(String[] args) throws InterruptedException, IOException {
    File f = new File("test.txt");
    f.createNewFile();
    PrintWriter txt = new PrintWriter("test.txt");
        txt.println("testing, testing, 1 2 3");
         txt.close();
    }
}

打印输出对象到java中的.txt文件
