### Question:
NumberFormatAtomicSignID implements SignIDProvider { @Override public int parse(String id) { return Integer.parseInt(id); } NumberFormatAtomicSignID();  NumberFormatAtomicSignID(String maxSignID); @Override void setCurrentMaxSignId(String maxSignId); @Override String incrementAndGet(); @Override String get(); @Override int parse(String id);  }### Answer:
@Test void parse() { NumberFormatAtomicSignID val = new NumberFormatAtomicSignID(); int actual = val.parse("079"); assertEquals(79, actual); }
