아주 많은 텍스트 필드가있는 애플리케이션을 만들었습니다. 내가 응용 프로그램을 실행할 때, 응용 프로그램은 abolutely 잘 작동합니다. 그런 다음 메뉴를 만들었습니다.이 메뉴는 응용 프로그램을 열거 나 FileWriter가 작성한 txt를 열 수 있습니다. 이제 메뉴를 사용하여 응용 프로그램을 실행하면 첫 번째 텍스트 필드에 초점을 맞 춥니 다. 첫 번째 textfield에 초점을 두지 않고 메뉴를 응용 프로그램에서 실행하게하려면 어떻게해야합니까 ?? 내가 말했듯이, 내가 메뉴없이 응용 프로그램을 실행할 때, 초점이 .. 희망 u는 도울 수있다! 최고 감사합니다.Java JTextfield 포커스

여기서'filewriter'는 무엇을 의미합니까? 그 기능이 내장되어 있습니까? 내 말은'FileWriter'가 아닌가? – vivek1794
