Newbie has simple question

I wrote a loop that reads a text file (NVRAM.TXT) and stores it in a big
character array and prints it out. It works fine. Just for the heck of
it I tried to break it into two files: one that does the reading and the
creation of the array, and another (with main) that prints out the first
10 characters of the array. It doesn't work. There's something wrong
with how I reference the array in the main program. The two files are
shown below, along with the error message that is generated. The
statement causing the error is:

System.out.print(bstr.nvchr[n]);

Please tell me how to make it work (if possible). Here are the two files:

public class NvrWork {
     public static void main(String[] args) {
         int n;
         BigString bstr = new BigString();
         for (n = 1; n < 10; n++) {

         System.out.print(bstr.nvchr[n]);

             }
         }
     }

public class BigString {

         public BigString() {
         int fin = 1;
         int count = 1;
         try {
         FileInputStream file = new FileInputStream("NVRAM.TXT");
         char[] nvchr = new char [30000];

             while (fin != -1) {
              fin = file.read();
              nvchr[count] = (char) fin;
              //System.out.print(nvchr[count]);
              count++;
             }
         System.out.println("Bytes read : " + count);
         file.close();
     } catch (IOException e){
         System.out.println("Could not read file");
     }

}
}

OUTPUT:

run:
Bytes read : 26017
Exception in thread "main" java.lang.RuntimeException: Uncompilable
source code - Erroneous tree type: <any>
    at NvrWork.main(NvrWork.java:9)
