System.out.println(" Income Statement"); System.out.print("Year: ");

                                Arrays.sort(Year);
                                System.out.print(Arrays.toString(Year));

The problem of this coding is that it will show null values before my user input value. Like this : Income Statement Year: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 2011] Month: Jan-Dec

I don't know how to sort the array in such a way that it still can function like this but without the null values.My array has a size of 20.
