### Question:
FloatParser implements ConfigurationParser { @Override public Set<Class> getResponsibleClasses() { Set<Class> responsibleClasses = new HashSet<>(); responsibleClasses.add(Float.class); responsibleClasses.add(float.class); return responsibleClasses; }  @Override Set<Class> getResponsibleClasses(); @Override Float parseValue(String value, Class targetType);  }### Answer:
@Test public void getResponsibleClasses() { Set<Class> responsibleClasses = parser.getResponsibleClasses(); assertTrue(responsibleClasses.contains(Float.class)); assertTrue(responsibleClasses.contains(float.class)); }
