    Default ascending sort

    Hi, i'm having problems making the sort be in ascending order instead of descending order.
    public static void main(String[] args) throws IOException, FileNotFoundException {
          int[] intArray = processFile("c:\\scores.txt");
            writeToFile ("c:\\scores.txt",intArray);    
        public static int[] processFile (String filename) throws IOException, FileNotFoundException 
                    int []intArray = new int[25];
                    int counter = 0;
    		int number;
    		BufferedReader inputReader = new BufferedReader (new InputStreamReader(new FileInputStream(filename)));
    		String line;
    		while((line = inputReader.readLine()) != null)
    			number= Integer.parseInt(line); 
                            intArray[counter] = number;
                    return intArray;
        public static int indexOfMaxInRange(int[] arr, int lowIndex, int highIndex) {
    	int indexOfMax = lowIndex;
    	for (int i = lowIndex+1; i <= highIndex; i++) {
    		if (arr[i] > arr[indexOfMax]) {
    			indexOfMax = i;
    		return indexOfMax; 
          public static void swapElement(int[] arr, int index1, int index2) {
    	int tempv = arr[index1];
    	arr[index1] = arr[index2];
    	arr[index2] = tempv; 
        public static int[] sortArray (int[] a) {
        for (int i=0; i>a.length; i++) {
          int j = indexOfMaxInRange (a, i, a.length-1);
          swapElement (a, i, j);}
            return a;
         public static void writeToFile (String filename, int[] Array) throws IOException {  
            BufferedWriter outputWriter = new BufferedWriter(new FileWriter(filename));
            int Num;
                for (int i = 0; i < 25; i++) {
                   if(i!=24) outputWriter.newLine();
    this is the output
    but i want it to be 1-25 in order....

    What - in your words - does the sortArray() do, and how does it do it?
