### Question:
MemoryRange { public static MemoryRange empty() { return NULL_RANGE; } private  MemoryRange(final long min, final long max); static MemoryRange of(final long value); static MemoryRange of(final long min, final long max); static MemoryRange empty(); MemoryRange add(final MemoryRange other); MemoryRange times(final long count); MemoryRange union(MemoryRange other); boolean isEmpty(); @Override boolean equals(final Object o); @Override int hashCode(); @Override String toString(); final long min; final long max; }### Answer:
@Test void emptyHasZeroMinMax() { MemoryRange empty = MemoryRange.empty(); assertEquals(0L, empty.min); assertEquals(0L, empty.max); }
