해결하고자 하는 문제

MainScreen, MultiClient, MultiClientThread, MultiServer, MultiServerThread로 되어 있습니다. MainScreen에서 chat버튼을 누르면 MultiClient로 만든 GUI가 나오면서 채팅이 시작되게 하고 싶습니다.

지금은 Client에 직접 id(nickname)과 ip를 명령행 인자로 받아서 MultiClient를 실행시키고 있는데 어떻게 하면 MainScreen에서 chat버튼을 누르면 MainScreen에서 설정했던 값들을 적용시켜서 MultiClient를 실행시킬 수 있을까요 ㅠ 방법을 모르겠습니다
코드 혹은 오류
