Question

ok so i’ve nearly got this. But it seems there is some logic error that i can’t get around. Note that i cannot use try/catch. No need to ask why

---

EDIT

for(String File : List){


        final String FilePath = getPath() + "/" + File;
        Render renderer = renderFile(FilePath);
        Runtime.getRuntime().addShutdownHook(new Thread(){
             public void run() {
                    deleteFile(FilePath);
                }
            });

        deleteFile(FilePath);
        updateReport(stuff);
        writeReportToFile(Report.toString());

I want it to delete the file that’s causing my crash .. if the app crashes but it doesn’t seem to be working. Am i calling it wrongly or what? confused

FINAL EDIT

OK after much toying around i finally got it to work!! Thanks everyone

Answer 1

From your last question I see, that you

• process images,
• one or more images will crash the JVM,
• we can’t catch that exception/error and
• we want to delete the corrupt image on the next run

An easy solution goes like that:

1. Each time, before you read bytes from an image file, persist the name of that image to a file (like: processingImage.txt)
2. Each time, an image has been processed succesfully, delete processingImage.txt
3. If the application crashes, then processingImage.txt contains the name of the offending image
4. If you start the application, check if processingImage.txt exists, read the name of the image, delete the image and delete processingImage.txt.
