    Default FIle Won't Delete

    Hello, I"m trying to delete a text file but to no avail.

    Here is the code
    File myFile = new File("test.txt");
    Scanner input = new Scanner(myFile);
    String oldText = "";
    while(inputOld.hasNextLine())
    {
    oldText = oldText + inputOld.nextLine();
    }
    input.close();
    myFile.delete();

    File is still there when I look. Path is correct, and the weird thing is if I create a new File in the code and point it an existing file without using scanners I can delete it.

    Example is:

    File myFile = new File("test.txt");
    myFile.delete()

    and that works... So my assumption is that because the file is being used by program I cannot delete it. How can I force my program to stop using the file since .close() method appears to not be working...

    First, you should evaluate the returned value by the delete method which tells you if the file has been deleted or not. If this returns true you should make sure you are pointing to the file you think you are pointing to. Second, do you ever you the scanner you created? Third, I'd recommend using a StringBuilder rather than String addition.

    I found the solution, input was not being closed in another method while reading the file. Thanks for the help, it had me confused for a while.
