[RESOLVED] NullPointer/warnings

[kolt007]

I was going to say that exact thing keang +D. Just because, the board instructions call for me to do so.
my solution:

           public static void readOutput() throws IOException{
    String allTxt;
    int cap;
    int read;
      try 
    (BufferedReader br = new BufferedReader(new FileReader(file))) {
          allTxt = br.readLine();
           cap = allTxt.length();
if(allTxt != null) {
  CharArrayWriter caw = new CharArrayWriter(cap);
    caw.write(allTxt, 0, cap);
  char[] araFull = caw.toCharArray();
 // code continues
