### Question:
Library { @Override public boolean equals(final Object other) { if (!(other instanceof Library)) return false; Library castOther = (Library) other; return new EqualsBuilder().append(uuid, castOther.uuid).isEquals(); } protected  Library();   Library(String uuid);  Library(Date dateAdded); String getUuid(); Date getDateAdded(); Set<Stat> getStats(); void addStat(StatInfo defaultStatInfo); @Override int hashCode(); @Override boolean equals(final Object other); @Override String toString();  }### Answer:
@Test public void testEquals() { Date dateAdded = new Date(); Library library1 = new Library(dateAdded); Library library2 = new Library(dateAdded); assertFalse("Two libraries created in the same moment " + "should not be equal.", library1.equals(library2)); }
