[Exception] throw 와 throw(ex) 의 차이점... 목요일, 12월 26, 2013 <span style="font-family: inherit;">개발을 진행하다 보면 Exception 정보의 중요성을 무시하는.. 아니 관심이 없는 개발자들을 많이 본다. Exception 정보야 말로 문제 해결의 근본적인 요소인데 말이다.</span><br /> <span style="font-family: inherit;"><br /> 그리고 많이 헷갈리는 것 중에 하나가 바로 throw 와 throw(ex) 의 차이점이다.</span><br /> <span style="font-family: inherit;"><br /> [ throw vs throw(ex) ]</span><br /> <span style="font-family: inherit;"><br /> 그냥 보기에는 이 둘에는 차이점이 전혀 없어 보인다. 그러나 명확한 차이점이 존재한다.</span><br /> <span style="font-family: inherit;"><br /> </span><br /> <div class="line number1 index0 alt2" style="background-color: rgb(242, 247, 249) !important;
