### Question:
Converter implements TreeConverter<E, MutableSettableStructuredNode<E>, LinkedTree<E>> { @Override public Class<? extends Tree> forClass() { return LinkedTree.class; }  @Override LinkedTree<E> build(Tree<E, S> sourceTree); @Override Class<? extends Tree> forClass();  }### Answer:
@Test public void forClass() { final Converter<String> converter = new Converter<>(); assertEquals(LinkedTree.class, converter.forClass()); }
