how to close a stream in a try/catch block

I have written a method to compare two file:

-----------------------------------------------------------------
  public static boolean compareFile(File file1, File file2) {
    BufferedInputStream in1, in2;
    try {
      in1 = new BufferedInputStream(new FileInputStream(
          file1));
      in2 = new BufferedInputStream(new FileInputStream(
          file2));
      int i;
      while ( (i = in1.read()) != -1) {
        if (i != in2.read()) {
          in1.close();
          in2.close();
          return false;
        }
      }
      if (in2.read() != -1) {
        in1.close();
        in2.close();
        return false;
      }
      in1.close();
      in2.close();
      return true;
    }
    catch (FileNotFoundException ex) {
      ex.printStackTrace();
    }
    catch (IOException ex) {
      ex.printStackTrace();
    }
    finally {
      //in1.close(); // compile error:might not been initialized
      //in2.close();
    }
      //in1.close(); // compile error:might not been initialized
      //in2.close();
    return false;
  }
----------------------------------------------------------------

I can't put the in1.close() into the finally block
the compiler say" variable in1 might not have been initialized"

so I must write it three times before every return sentence
it's so bothering...do you have any better idea?

and it still have a problem
when it catch a exception,it will not reach the in1.close()
so when it bring on exception the stream can't be closed

Thank you very much in advance
