### Question:
ParseChar implements IsParser<Character> { @Override public Character parse(Object o, Field field) { return isValid(o) ? o.toString().charAt(0) : null; }  @Override Character parse(Object o, Field field); @Override void setCell(Character o, Cell cell, Field field);  }### Answer:
@Test public void parse() throws Exception { Character actual = parseChar.parse(null, null); assertEquals(null, actual); actual = parseChar.parse(expected, null); assertEquals(expected, actual); }
