Ok, so I managed to come up with:

        	String []array=strLine.split("\n");
        	for(String s: array)
        	{
        		System.out.println(s);
        	}

...which seems to work. Any hints on how I could sort the ints (with attached strings) in ascending order, without changing the order of the strings ?

I am actually required to use a BST, and although I've read through some tutorials, I still can't seem to understand the application of it...

I did try that, but then it prints everything on one line without spaces, i.e.:

1catsdogs2menwomen3applespears4bricksstones

Also, some of the words aren't alphabetically, but I don't want to sort that out... The strings must only be re-arranged based on their key/int values

Uhm, it's actually compulsory for me to use the BST though... That's why I was trying to figure out a way to use String Tokenizer

So I tried using the String split (never used it before):

    while ((strLine = br.readLine()) != null)   
    {
        String firstWord, restOfString=" ";
        
        String [] aSplit= strLine.split (" ");
        firstWord=aSplit[0];
        
        for (int i=1; i<aSplit.length; i++)
        {
        	restOfString += aSplit[i];
        	restOfString += " ";
        	
        	System.out.println (firstWord + restOfString);
        	}
    }

But my prints out:

3 apples
3 apples pears
1 cats
1 cats dogs
4 bricks
4 bricks stones
2 men
2 men women

Any suggestions?

I tried

 public static String [] readFile (String fileName) throws IOException
   {
Scanner s = new Scanner (new FileReader (fileName));
	 while (s.hasNextLine()) {
     String [] file = scanner.nextLine();   
       { int i=0;
         file[i] = s.nextLine ();
      }
      s.close ();
      return file;
      }
   } 

It says "Exception in thread "main" java.lang.Error: Unresolved compilation problem:
scanner cannot be resolved"
