I wanted to readchar() from a TXT pad, and store all the letters other
than spaces and dots and comma in a ONE dimensional array

So here is my questions:

FileInputStream fin = new FileInputStream("blah.txt");
                        DataInputStream infile = new DataInputStream(fin);

                        char array[] = new char[800];

                        // Read each line of the file as a string

                        while (infile.available() != 0)
                        {

                                array[i] = infile.readChar();
                                if(array[i] == 'A')
                                        i++;

                        }

first i switch to data string, so i don't think i have to worry about
end of line, and then i only reads Captial letters A
would that work?
is there any other way doing this>?

Your question is ambiguous. What has "Capital letters A" to do with
the solution to the problem? In the code that you have posted

char array[] = new char[800];

/** What if the file size is more than 800 char? Better way to create
Array would be to initialize it according to the size of the file
being read. **/

  while (infile.available() != 0) {
    array[i] = infile.readChar();
    if(array[i] == 'A') /** What's the purpose of doing this? **/
      i++; // *** i is never declared, have you declared it elsewhere?
   }

Simply create a StringBuffer Object and iterate over it, use regex if
you would like to filter out space, comma, whatever

is there any other way doing this>?

Of course there are better ways of doing it.
