교육개요

* 09:30 ~ 17:00 (30시간 / 5일) (점심시간:1시간30분)

이 과정은 자바 기반의 객체 지향 어플리케이션을 설계하는 데 사용되는 핵심적인 응용
프로그래밍 인터페이스(API)들을 다루고, 기존 클래스의 서브 클래스를 만들거나 추상 클래스를 확장하는 방법, 인터페이스를 사용하는 프로그래밍 기법을 배우게 됩니다.
예외를 적절하게 활용하는 방법과 컬렉션 프레임워크의 사용 방법 등을 학습하고 파일 시스템의 파일과 디렉터리를 조작하는 응용 프로그램을 개발해 볼 수 있습니다.
또한 멀티스레드 프로그램을 올바르게 작성하는 방법과 JDBC를 사용하여 데이터베이스와
연동하는 프로그램을 작성하는 방법도 학습할 수 있습니다. 아울러 자바 SE 7에 추가된 자바
언어의 새로운 모습과 NIO.2 등 향상되고 개선된 사항들을 확인하실 수 있습니다.

이 과정은 자바 언어를 활용한 개발 능력을 향상시킬 수 있을 뿐만 아니라 오라클 인증 자바
프로그래머 자격(Oracle Certified Professional, Java SE 7 Programmer)의 준비에도 도움이
됩니다.
