    Default Radix sort Issues??? Help

    I am having issues getting this Radix sort program to work properly. I know I am overlooking something but I am at a loss to what it is.

    public class SortArrayAll{
     
    	public static void radixSort(String[] array, int n, int d){
    	    ADTQueue<String>[] sort = new ADTQueue[n];
            for (int k = 0; k < n; k++){ // create ADTQueue based on size of array
                sort[k] = new ADTQueue();
            }
            for(int i=0; i<d;i++){
                for(int j=0; j<n;j++){
                   char num = (array[j].charAt(i));
                   int sort1 = Integer.parseInt(Character.toString(num));
                     sort[sort1].enqueue(array[j]);
                }
               int Counter=0;
                  for(int k=0; k<sort.length;k++){
     
                   while(!sort[k].isEmpty()){
                     array[Counter]=(String)sort[k].dequeue();
                     Counter++;
                   }
     
                   //you need to implement this sorting method
                 }
              }
           }
     
     
    	public static void main(String[] args){
    		String[] array = GenerateData.getData(20);
    		int n = array.length;
    		int d = array[0].length();
     
    		System.out.println("Origianl Data");
    		displayArray(array);
     
    		radixSort(array, n, d);
     
    		System.out.println("\nSorted Data");
    		displayArray(array);
     
    	}
     
    	static <T> void displayArray(T[] array){
    		for(int i=0;i<array.length; i++){
    			System.out.print(array[i]+" ");
    		}
    			System.out.print("\n");
    	}
     
    }

    The sort method will only sort single digit variables it will not sort double digit variable correctly.
