I am having problems writing the contents of an array to file.

The following is the code I am using to show the array on the screen with correct formatting:

public void output()

    {

    System.out.println("Item Cost  Quantity  Description" );

    System.out.println("==================================================" );

    for (int outputIndex = 0; outputIndex < countItems; outputIndex++)

        {

        System.out.printf("%9.2f %10d   %s\n", items[outputIndex].getCost(), items[outputIndex].getQuantity(), items[outputIndex].getDescription());

        }

    System.out.println("==================================================" );

    System.out.println(" ");

    }

Which works just fine. However, when I use similar code for outputting to file it fails to write anything and instead saves a blank page in the file:

public void save() throws IOException

    {

    FileWriter fwriter = new FileWriter("shopping.dat");

    PrintWriter outputFile = new PrintWriter(fwriter);

 

    for (int saveIndex = 0; saveIndex < countItems; saveIndex++)

        {

        outputFile.printf("%9.2f %10d   %s\n", items[saveIndex].getCost(), items[saveIndex].getQuantity(), items[saveIndex].getDescription());

        }

    upToDate = true;

    }

Please help me???

Try adding

outputFile.close(); 

in the end
