### Question:
LoincId implements Serializable { @Override @JsonValue public String toString() { return String.format("%d-%d",num,suffix); } LoincId(String loinccode);  LoincId(String loinccode, boolean hasPrefix); @Override boolean equals(Object o); @Override int hashCode(); @Override @JsonValue String toString();  }### Answer:
@Test public void testConstructor() throws MalformedLoincCodeException { String code = "15074-8"; LoincId id = new LoincId(code); assertEquals(code,id.toString()); }
@Test public void testConstructor2() throws MalformedLoincCodeException { String code = "3141-9"; LoincId id = new LoincId(code); assertEquals(code,id.toString()); }
@Test public void testBadCode() { Assertions.assertThrows(MalformedLoincCodeException.class, () -> { String code = "15074-"; LoincId id = new LoincId(code); assertEquals(code,id.toString()); }); }
@Test public void testBadCode2() throws MalformedLoincCodeException { Assertions.assertThrows(MalformedLoincCodeException.class, () -> { String code = "1507423"; LoincId id = new LoincId(code); assertEquals(code, id.toString()); }); }
