### Question:
BooleanType implements ExtendedType<Boolean> { @Override public String getClassName() { return Boolean.class.getName(); }  @Override String getClassName(); @Override void setJdbcObject(
            PreparedStatement st,
            Boolean val,
            int pos,
            int type,
            int precision); @Override Boolean materializeObject(ResultSet rs, int index, int type); @Override Boolean materializeObject(CallableStatement st, int index, int type); @Override String toString(Boolean value);  }### Answer:
@Test public void testClassName() { BooleanType type = new BooleanType(); assertEquals(Boolean.class.getName(), type.getClassName()); }
