Java.io.filenotfoundexception文件路径（访问被拒绝）

Question

我制作了.exe文件（使用launchj4和inno install creater）。在java文件（Netbeans Project）中，它可以正常工作，我可以编辑和更改数据，但是当我尝试在exe文件中使用它时，它会给出Exception，它只读取文件。

它还显示了Customer.txt和其他2的确切路径，但是当我尝试编写它时：

  

java.io.FileNotFoundException C：\ Program Files（x86）\ MyApp \ Customer.txt（拒绝访问）

代码：

public DataInOut()
    {
    customer = new File("Customer.txt");
    Sale = new File("SaleReport.txt");
    Salesman = new File("SaleMan.txt");
    path_Customer = customer.getAbsolutePath();
    path_Sale = Salesman.getAbsolutePath();
    path_Report = Sale.getAbsolutePath();
    WriteCustomer = new File(path_Customer);
    WriteSale = new File(path_Report);
    WriteSalesMan = new File(path_Sale);
}

public void dataIn()

        int i =0;

                String text = CBR.readLine();
                if(text!=null)
                {
                    String[] arr = text.split("=");
                    int index = Integer.parseInt(arr[5]);
                    arr_customer[index] = text;
