### Question:
SplitLevel { @Override public int hashCode() { return Objects.hash(level, orientation); } private  SplitLevel(int level); int getLevel(); Orientation getOrientation(); static SplitLevel valueOf(int level); @Override int hashCode(); @Override boolean equals(Object obj); @Override String toString(); static final SplitLevel ROOT; }### Answer:
@Test @Disabled public void testHashCode() { System.out.println("hashCode"); SplitLevel instance = null; int expResult = 0; int result = instance.hashCode(); assertEquals(expResult, result); fail("The test case is a prototype."); }
