Java Programming

Maybe I'm just missing something, but I thought this code should work. The program never ends. It's supposed to read a text file, and combine the ASCII values of each letter of each word to come up with "total". It then divides total by the hash value to get its corresponding place in the array. After it's all said and done, I want to print the each word and hash value of the word in the array, along with the number of collisions. Would someone please help me with the problem and offer any helpful hints or solutions? Thanks!

public class HashTable {
  private HashObject[] hashArray; 
  private String word;
  private HashObject hashItem;

  private int arraySize;

  public HashTable(int size) {
    arraySize = size;
    hashArray = new HashObject[arraySize];
  }

  public void displayTable() {
    System.out.print("Table: ");
    for (int j = 0; j < arraySize; j++) {
      if (hashArray[j] != null)
        System.out.print(hashArray[j].getValue() + " " + hashArray[j].getWord() + " ");
      else
        System.out.print("#");
    }
    System.out.println("");
  }

  public int hashFunction(int key) {
    return key % arraySize; 
  }
  
  private void insert(HashObject item){
    int key = item.getValue(); 
    int hashVal = hashFunction(key); // hash the key
    // until empty cell,
    while (hashArray[hashVal] != null) {
      ++hashVal; // go to next cell
      hashVal %= arraySize; // wraparound if necessary
    }
    hashArray[hashVal] = item; // insert item
  }

  public HashObject find(int key) // find item with key
  {
    int hashVal = hashFunction(key); // hash the key

    while (hashArray[hashVal] != null) // until empty cell,
    { 
      if (hashArray[hashVal].getValue() == key)
        return hashArray[hashVal]; // found, return item
      ++hashVal; // go to next cell
      hashVal %= arraySize; // wraparound if necessary
    }
    return null; // can't find item
}

				hashItem = new HashObject(total, word);
				insert(hashItem);
				} // end for
