아 문법 오류인 것 같은데 위 빨간색에 커서를 갖다 대면이렇게 뜹니다

음... · Answer

byPassThread 생성자의 인자가 맞질 않네요.. 런타임 오류로 가기전에 빌드 자체가 안될것 같은데요..new byPassThread(sock,this,keyboard); 가 아니고new byPassThread(sock,this.keyboard); 할려고 한게 아닌지...

물개 · Answer

그렇게 해도 안되네요 ㅠㅠ 초보라 문법 자체를 모르겠네요 ㅠㅠ

leani · Answer

코드에 대한 이해 없이 그냥 control c v 하니까 이러지요..인자값이 안맞는데 코드가 어떻게 굴러갑니까..
