Java File I/O problem

Hello,

I am trying to read in all the data from a file and return it in an array of the appropriate type.
Here is my code but i always get the following error:

cannot resolve symbol
symbol : variable available
location: class java.io.BufferedReader
while (din.available != 0)

Here is my code:

public static String[] readAllStrings ( String filename )
      throws FileIOException
{
      try {
      String temp;
      int j = 0;

      FileInputStream fin = new FileInputStream(filename);
      BufferedReader din = new BufferedReader(new InputStreamReader(fin));

      while (din.available != 0)
      {
            temp.concat(din.readLine());
      }

      StringTokenizer st = new StringTokenizer(temp);

      String[] strArray = new String(st.countTokens());


      while(st.hasMoreTokens()){
            strArray[j] = st.nextToken();
            j++;
      }


      }
      catch (IOException e)
      {
      }

}

Please help.

Thanks

PS: This is my assignment.

Hello,

I am sorry but I have one more error:

cannot resolve symbol
symbol : constructor String (int)
location: class java.lang.String
String[] strArray = new String(st.countTokens())

THanks
