more project help please....?

ok this is a really tricky one that i cant figure out what to do i kind of know whats wrong but i cant figure out how to fix it, i've tried several things but to no avail...

i've created a slectionsort object that creates an array of strings from reading in from a text file, it also has methods to display the array and sort the array.

public class SelectionSort {
  private String[] a;

  private int nElems;
  String sWord;

  public SelectionSort(int max) {
    a = new String[max];
    nElems = 0;
  }

  public void insert(String value) {
    a[nElems] = value;
    nElems++;
  }

  public void display() {
    for (int j = 0; j < nElems; j++)
      System.out.print(a[j] + " ");
    System.out.println();
  }

  public void selectionSort() {
    int out, in, min;


    for (out = 0; out < nElems - 1; out++) // outer loop
    {

      min = out; // minimum

      for (in = out + 1; in < nElems; in++){
        // inner loop

        int x = a[in].compareTo(a[min]);

        if (x < 0) // if min greater,
            min = in; // a new min

        }

      swap(out, min); // swap them
    }
  }



  private void swap(int one, int two) {
    String temp = a[one];
    a[one] = a[two];
    a[two] = temp;
  }

  public String getWord()
  {
	  for(int i = 0; i< nElems; i++)
	  {
		  sWord = a[i];


	  }
		return sWord;
  }

this part works fine but i added a method called search array which is meant to search through the array and make a new array of wordcountobjects which searches the original array of strings for individual words, creates a new wordcountobject with the word and the number of times it appears

public void SearchArray(SelectionSort[] a)
{

WordCountObject []wordcount = new WordCountObject[1000000];


	for (int i=0; i<a.length; i++)

  	{
    	boolean found = false;
    	int nElems = 0;

			for(int k=0;k<nElems;k++)
			{
				if (a[i].getWord() == wordcount[k].getWord())
    			{
      				wordcount[k].increment();
      				found = true;
      				break;
    			}

    			else
    			{
					wordcount[k].addWord(a[i].getWord());
					wordcount[k].increment();
					nElems++;

				}


  			}

	}


}
}

the problem is when i go to use the searcharray method on the original array i get this error...

G:\Algo\project\FileTest2.java:63: SearchArray(SelectionSort[]) in SelectionSort cannot be applied to (SelectionSort)
wordArray.SearchArray(wordArray);
^
1 error

I believe this is because the searcharray method is incompatible with the selectionsort??

I have tried changing it to take in just a string array and added methods to get the strings out of the objects to no avail, is there something missing or is my code just a big mess that wont work at all?
