### Question:
PageRange { @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; PageRange pageRange = (PageRange) o; if (mLowerBound != pageRange.mLowerBound) return false; if (mUpperBound != pageRange.mUpperBound) return false; return true; } private  PageRange(int lowerBound, int upperBound); int getLowerBound(); int getUpperBound(); boolean isRange(); @NotNull static PageRange parse(@NotNull String pages); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testEquals() throws Exception { EqualsVerifier.forClass(PageRange.class).verify(); }
