   javaintro.pdf Java"Java" generally refers to a combination of three things: the Java programming language (a high-level, object-oriented programming language); the Java Virtual Machine (a high-performance virtual machine that executes bytecodes on a specific computing platform, typically abbreviated JVM); and the Java platform, a JVM running compiled Java bytecodes, usually calling on a set of standard libraries such as those provided by Java Standard Edition (SE) or Enterprise Edition (EE). Though coupled by design, the language does not imply the JVM, and vice versa. In this Article The Java Programming Language The Java Platforms The Java Virtual Machine The JVM Without Java The Java Community Process Conclusions We recently received an email asking for a "...

워낙 유명한 신상철 박사님의 사이트 javapassion에서 공부한지 벌써 1년이 다되어 가지만 항상 하다가 끊기고 하다가 끊기고 해서 이번주 ~ 마음을 잡고 처음부터 한번 다시 도전을 해보기로 했다. 새해가 된 만큼 열심히 노력해서 꼭 가고 싶은 회사에 들어가고야 말곘다라고~~ 사이트는 이렇게 생겼다.  이번주내로 javase는 끝낼수 있도록 해보자~~ 파이팅~
