### Question:
VectorMatchResultMap { @Nonnull static String[] splitFieldMatchNames(String theFieldMatchNames) { return theFieldMatchNames.split(",\\s*"); } VectorMatchResultMap(EmpiRulesJson theEmpiRulesJson); @Nonnull EmpiMatchResultEnum get(Long theMatchVector); long getVector(String theFieldMatchNames); String getFieldMatchNames(long theVector);  }### Answer:
@Test public void splitFieldMatchNames() { { String[] result = VectorMatchResultMap.splitFieldMatchNames("a,b"); assertEquals(2, result.length); assertEquals("a", result[0]); assertEquals("b", result[1]); } { String[] result = VectorMatchResultMap.splitFieldMatchNames("a, b"); assertEquals(2, result.length); assertEquals("a", result[0]); assertEquals("b", result[1]); } }
