### Question:
PrimitiveFloatWrapper extends FloatWrapper { @Override public Float getDefault() { return defaultValue; } PrimitiveFloatWrapper();  PrimitiveFloatWrapper(float value); @Override void set(Number v); @Override Float getDefault(); @Override boolean isPrimitiveWrapper(); @Override R accept(WrapperVisitor<R, P, Q, TH> visitor, P p, Q q);  }### Answer:
@Test void getDefault() { PrimitiveFloatWrapper wrapper = new PrimitiveFloatWrapper(); assertEquals(0f, wrapper.getDefault()); }
