### Question:
NoPointSensitivity implements PointSensitivityBuilder { @Override public NoPointSensitivity cloned() { return this; } private  NoPointSensitivity(); @Override PointSensitivityBuilder withCurrency(Currency currency); @Override PointSensitivityBuilder mapSensitivity(DoubleUnaryOperator operator); @Override PointSensitivityBuilder combinedWith(PointSensitivityBuilder other); @Override NoPointSensitivity normalize(); @Override MutablePointSensitivities buildInto(MutablePointSensitivities combination); @Override NoPointSensitivity cloned(); @Override String toString();  }### Answer:
@Test public void test_cloned() { PointSensitivityBuilder base = PointSensitivityBuilder.none(); PointSensitivityBuilder test = base.cloned(); assertThat(test).isSameAs(base); }
