      public static <T, E extends Throwable> T[] fill(T[] array, FailableIntFunction<? extends T,E> generator) throws E
      Fills and returns the given array, using the provided generator supplier to compute each element. Like Arrays.setAll(Object[], IntFunction) with exception support.

      If the generator supplier throws an exception, it is relayed to the caller and the array is left in an indeterminate state.

      Type Parameters:
      T - type of elements of the array.
      E - The kind of thrown exception or error.
      Parameters:
      array - array to be initialized.
      generator - a function accepting an index and producing the desired value for that position.
      Returns:
      the input array
      Throws:
      E - Thrown by the given generator.
