title: count amount of unique words in a text file? (Not allowed to use Hash)
body: <p>How can I count repeated words in a text file, using an array?</p>
  
  <p>My program is able to print out total words in the file, But how can I get my program to print the number of different words and also have printed out a list of the number of the repeated words like this:</p>
  
  <p>Cake: 4
  a: 320
  Piece: 2
  of 24</p>
  
  <p>   (Words with capital letters and small letters are considered the same word)</p>
  
  <pre><code>void FileReader() { 
  
  
      System.out.println("Oppgave A");
      int totalWords = 0; 
      int uniqueWords = 0; 
      String [] word = new String[35000];
      String [] wordC = new String [3500];
      try {
          File fr = new File("Alice.txt");
          Scanner sc = new Scanner (fr);
  
          while(sc.hasNext()){
          String words = sc.next();
          String[] space = words.split(" ");
          String[] comma = words.split(",");
              totalWords++;
  
  
              }
          System.out.println("Antall ord som er lest er: " + totalWords);         
      } catch (Exception e) {
  
          System.out.println("File not found");
  
      }
