not implemented, but you will not need those details. Assume filename is a String, x is an int, a
is a double array and i is an int. Use the comments i1, i2, i3, e1, e2, e3, e4, e5 to answer the
questions (i for instruction, e for exception handler).

An exception raised by the instruction in i1 would be caught by the catch statement labeled




try { BufferedReader infile = new BufferedReader(new FileReader(filename)); // i1 int x =
Integer.parseInt(infile.readLine( )); // i2 a[++i] = (double) (1 / x); // i3 } catch
(FileNotFoundException ex) {...} // e1 catch (NumberFormatException ex) {...} // e2 catch
(ArithmeticException ex) {...} // e3 catch (ArrayIndexOutOfBounds ex) {...} // e4 catch
(IOException ex) {...} // e5
