### Question:
LongRangeOperations extends RangeOperations<Long> { @Override public Long getValue(String valueString) { return Long.parseLong(valueString); }  @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 testGetValue() { Long actual = longRangeOperations.getValue("12"); Long expected = new Long(12); assertEquals(expected, actual); }
