### Question:
DIMACSExporter extends AbstractBaseExporter<V, E> implements GraphExporter<V, E> { public DIMACSFormat getFormat() { return format; } DIMACSExporter();  DIMACSExporter(ComponentNameProvider<V> vertexIDProvider);  DIMACSExporter(ComponentNameProvider<V> vertexIDProvider, DIMACSFormat format); @Override void exportGraph(Graph<V, E> g, Writer writer); boolean isParameter(Parameter p); void setParameter(Parameter p, boolean value); DIMACSFormat getFormat(); void setFormat(DIMACSFormat format); static final DIMACSFormat DEFAULT_DIMACS_FORMAT; }### Answer:
@Test public void testDefaultFormat() { DIMACSExporter<String, DefaultWeightedEdge> exporter = new DIMACSExporter<>(); assertEquals(DIMACSFormat.MAX_CLIQUE, exporter.getFormat()); }
