### Question:
Impression implements Serializable { public H3 getH3() { return h3; } Impression();  Impression(H0 h0, H1 h1, H2 h2, H3 h3);  Impression(Double[] dayCounts);  Impression(double[] dayCounts);  Impression(Map map); Long getTotal(); double getValueForHIndex(int h_index); long countImpressions(double price, TargetingChannel.PriceModel priceModel); H1 getH1(); void setH1(H1 h1); H0 getH0(); void setH0(H0 h0); H2 getH2(); void setH2(H2 h2); H3 getH3(); void setH3(H3 h3); Integer getH_index(); void setH_index(Integer h_index); void adjustPositive(); List<Double> getHs(); static Impression add(Impression i1, Impression i2); static Impression subtract(Impression i1, Impression i2); static Impression multiply(Impression i1, double r); long getCountByPriceCategory(int priceCategory); long getIndividualHistogramCountByPriceCategory(int priceCategory); void adjustValue(int priceCategory, long t); @Override String toString(); static final int TOTAL_NUM_OF_PRICE_CATEGORIES; }### Answer:
@Test public void getH3() { H3 h3 = new H3(); h3.setH("33"); h3.setT((long) 3); Impression imp = new Impression(new H0(), new H1(), new H2(), h3); assertEquals(h3, imp.getH3()); }
