Help me to display result

Question

this is my class that i want to get result from :
class QuickSorter
     long StartTime, EndTime,Compare=0, Move=0;
     int[] array;
     public QuickSorter(int[] unSorted)
          array=unSorted;
public void quickSort(int lowIndex, int highIndex)
          int lowToHighIndex;
     int highToLowIndex;
     int pivotIndex;
     int pivotValue;
     int lowToHighValue;
     int highToLowValue;
     int parking;
     int newLowIndex;
     int newHighIndex;
     int compareResult;
     lowToHighIndex = lowIndex;
     highToLowIndex = highIndex;
     pivotIndex = (lowToHighIndex + highToLowIndex) / 2;
     pivotValue = array[pivotIndex];
     newLowIndex = highIndex + 1;
     newHighIndex = lowIndex - 1;
     while ((newHighIndex + 1) < newLowIndex) // loop until partition complete
          { // loop from low to high to find a candidate for swapping
          lowToHighValue = array[lowToHighIndex];
          while ((lowToHighIndex < newLowIndex)&& (pivotValue>lowToHighValue ))
               newHighIndex = lowToHighIndex; // add element to lower part
          lowToHighIndex ++;
          lowToHighValue = array[lowToHighIndex];
// loop from high to low find other candidate for swapping
          highToLowValue = array[highToLowIndex];
          while (newHighIndex <= highToLowIndex && pivotValue<highToLowValue)
               newLowIndex = highToLowIndex; // add element to higher part
          highToLowIndex --;
          highToLowValue = array[highToLowIndex];
// swap if needed
if (lowToHighIndex == highToLowIndex) // one last element, may go in either part
{ newHighIndex = lowToHighIndex; // move element arbitrary to lower part
else if (lowToHighIndex < highToLowIndex) // not last element yet
{ compareResult = array[highToLowValue];
if (compareResult >= 0) // low >= high, swap, even if equal
{ parking = lowToHighValue;
array[lowToHighIndex]=highToLowValue;
array[highToLowIndex]=parking;
newLowIndex = highToLowIndex;
newHighIndex = lowToHighIndex;
lowToHighIndex ++;
highToLowIndex --;
if (lowIndex < newHighIndex)
     quickSort(lowIndex, newHighIndex); // sort lower subpart
if (newLowIndex < highIndex)
     quickSort(newLowIndex, highIndex); // sort higher subpart
then i want to get the result from call the method quickSort to a JPanel
public void actionPerformed(ActionEvent evt)
if(evt.getActionCommand().equals("3")&&passed3!=true)
          QuickSorter QSort=new QuickSorter(array);
               QSort.quickSort(0,array.length-1);
          TF3.setText(""+QSort.EndTime);
          CF3.setText(""+QSort.Compare);
          MF3.setText(""+QSort.Move);
               passed3=true;
               int[] sortedarray=array;
               System.out.println("the list sorted by Quicksort is:");
               display(sortedarray);
               array=getBack(n);
but the run time error is display when i run it, plz help

Answer 1

1) Use the code tags when posting code
2) So there's a runtime error. Do you expect us to guess what it is or will you tell us?
