### Question:
ByValueAscComparator implements Comparator<NumericIDValue>, Serializable { @Override public int compare(NumericIDValue a, NumericIDValue b) { float aValue = a.getValue(); float bValue = b.getValue(); if (aValue < bValue) { return -1; } if (aValue > bValue) { return 1; } long aItem = a.getID(); long bItem = b.getID(); if (aItem > bItem) { return -1; } if (aItem < bItem) { return 1; } return 0; } private  ByValueAscComparator(); @Override int compare(NumericIDValue a, NumericIDValue b);  }### Answer:
@Test public void testCompare() { NumericIDValue a = new NumericIDValue(1L, 2.0f); NumericIDValue b = new NumericIDValue(5L, 1.0f); assertTrue(ByValueAscComparator.INSTANCE.compare(a, b) > 0); assertTrue(ByValueAscComparator.INSTANCE.compare(b, a) < 0); assertEquals(0, ByValueAscComparator.INSTANCE.compare(a, a)); }
@Test public void testSameValue() { NumericIDValue a = new NumericIDValue(1L, 2.0f); NumericIDValue b = new NumericIDValue(5L, 2.0f); assertTrue(ByValueAscComparator.INSTANCE.compare(a, b) > 0); assertTrue(ByValueAscComparator.INSTANCE.compare(b, a) < 0); assertEquals(0, ByValueAscComparator.INSTANCE.compare(a, a)); }
