### Question:
DefaultSimilarityClassifier implements SimilarityClassifier<T> { @Override public boolean areSimilar(T obj1, T obj2) { return calculateSimilarity(obj1, obj2) >= threshold; }  @Override boolean areSimilar(T obj1, T obj2); @Override SimilarityClassifier<T> asClassifier(double newThreshold); @Override String toString();  }### Answer:
@Test public void test() { assertThat(getClassifier(0.6).areSimilar("foo", "bar")).isFalse(); assertThat(getClassifier(0.5).areSimilar("foo", "bar")).isTrue(); assertThat(getClassifier(0.4).areSimilar("foo", "bar")).isTrue(); }
