### Question:
LongRangeOperations extends RangeOperations<Long> { @Override public Long getMaxValue() { return Long.MAX_VALUE; }  @Override Long getValue(String valueString); @Override Long getMinValue(); @Override Long getMaxValue(); @Override Long add(Long value, int step); @Override Long subtract(Long value, int step);  }### Answer:
@Test public void testMaxValue() { Long actual = longRangeOperations.getMaxValue(); Long expected = Long.MAX_VALUE; assertEquals(expected, actual); }
