[Java001]자바(Java)란 무엇인가?
1. 자바의 탄생
자바는 1991년1991년 6월 가정용 전자제품에서 작동하는 프로그램을 개발할 목적적인셋톱 프로젝트를 위해 제임스 고슬링(James Gosling)이 만들었다. 당시 Sun은 가전제품용 프로그램을 C++로 작성하였다. 하지만 C++에서 제공하는 기능들이 너무 다양하고 문법이 복잡해서 단순한 가전제품에 어울리지 않다고 판단하였다. 그래서 가전제품에 탑재가능한 언어를 만들게 된다. 이것이 현재 의 모체가 되는 오크(Oak)라는 언어이다.원래 제임스 고슬링의 사무실 밖에 있던 오크 나무를 따라 오크(Oak), 혹은 그린(Green) 이라고도 불렀으나 단어 리스트 중 무작위로 뽑은 자바(Java)를 선택했다.
자바의 목표이자, 고슬링의 목표는 개발자의 확보와 사용자 편의성을 고려하여 C/C++ 스타일의 언어를 만드는 것과 어떤 기계에서도 동작할 수 있도록 하는 것이였다. 모든 기계에서 독립적으로 실행 가능하도록 만들기 위해서 가상 머신을 설계하고 구현하였다. 그 당시 회사내에서 월드와이드웹이 활발하게 사용되기 시작한 시점에, Sun의 창업자의 한 명인 빌 조이(Billjoy)는 오크가 인터넷과 웰드 와이드 웹에 사용될 수 있다는 가능성을 발견하게 되었고 빌 조이의 판단에 따라 FirstPerson 프로젝트를 이끌던 제임스 고슬링(James Gosling)과 패트릭 녹턴(patrick Naughton)이 오크 언어를 완벽한 인터넷 개발 환경으로 만드는 작업을 시작하여 1995년 중반에 자바 언어가 공식적으로 발표되기 이르렀다.

첫 공개 버전은 1995년의 자바 1.0 이었다. 한번 쓰고 어느 곳에도 실행 "Write Once, Run Anywhere" 하는 것을 약속하였고 인기 플랫폼에 무료 런타임을 제공하였다. 이 플랫폼은 꽤 안정성을 지녔고 보안 시스템은 여러 설정을 통해 네트워크 및 파일 접근을 통제할 수 있었다. 대부분의 브라우저들은 곧 자바 애플릿(Java Applet) 을 웹 페이지 안에서 실행할 수 있었고 자바의 인기는 급상승했다.
국내에선 1999년 새롬기술이 ‘다이얼패드’라는 인터넷 무료전화 서비스를 출시해 이른바 ‘대박’을 터뜨렸다. 광고를 보면 해외에 있는 지인과도 무료 통화를 할 수 있게 한 시스템이였는데, 새롬기술은 서비스 출시 한 달 만에 주가 30만원을 기록하며 삼성전자 시가총액을 능가하는 황제주로 부상했다1. 비록 다이얼 패드는 성공하지 못했지만 한 때 미국시장에 성공적으로 진출했다는 평가를 받았고 전성기일 때는 1000만명에 이르는 가입자를 확보한 적도 있었다. 그런데 다이얼 패드가 사용했던 기술이 바로 Java Applet이었다. 성공은 못했지만 사람들의 관심을 끌기 시작했고 자바 자체가 인터넷을 염두에 두고 고안했던 언어였기 때문에 인터넷의 급속한 발전과 함께 자바 또한 급속하게 성장하게 된다. 이를 시기한 마이크로소프트에 의해 웹브라우저에서 VM이 빠진 적도 있었지만 열화와 같은 대중의 욕지거리에 힘입어 VM을 다시는 뺄 수 없게 된적도 있었다.
자바 2 (JDK 1.2 ~ 1.4) 의 출현으로 여러 다양한 플랫폼에서 사용 할 수 있는 설정(Configuration) 들을 만들었다. 예를 들어 J2EE 는 엔터프라이즈 애플리케이션을 실행할 수 있고 J2ME 는 모바일 애플리케이션을 실행할 수 있다. J2SE는 스탠다드 에디션 으로 지정되었다. 2006년에 마케팅 용으로 Java EE, Java ME, Java SE 순서대로 명칭을 바꾸었다.
현재 자바는 3가지 에디션을 가지고 있는 데 Java ME, Java SE, Java EE가 그것이다. 휴대폰, PC, 대기업 서버에 각각 사용된다. 라고 생각해도 크게 무방할 것이다.
자바 플랫폼 마이크로 에디션(Java Platform, Micro Edition, 약자 Java ME)을 말한다. Java 2 Platform, Micro Edition라고도 불리며, Java ME 혹은 J2ME 등으로도 널리 알려져 있다. 제한된 자원을 가진 휴대전화, PDA, 세트톱박스 등에서 Java 프로그래밍 언어를 지원하기 위해 만들어진 플랫폼 중 하나를 가리킨다.
자바 플랫폼 스탠더드 에디션(Java Platform, Standard Edition, 약자 Java SE)는 자바 플랫폼에서 가장 널리 쓰이는 자바 API의 집합체이다. 예전에는 J2SE로 불리었으나 버전 6.0이후에 Java SE로 변경되었다. 이전에는 썬 마이크로시스템즈에서 관리하였으나, J2SE 1.4 이후는 JCP 주도하에 개발되고 있다. 따라서, JSR 59에는 J2SE 1.4를, JSR 176에는 J2SE 5.0(프로젝트명 타이거)를, Java SE 6 (프로젝트명 무스탕)은 JSR 170 하에 개발되었다.
자바 플랫폼, 엔터프라이즈 에디션(Java Platform, Enterprise Edition, 약자 Java EE)은 자바를 이용한 서버측 개발을 위한 플랫폼이다. Java EE 플랫폼은 PC에서 동작하는 표준 플랫폼인 Java SE에 부가하여, 웹 애플리케이션 서버에서 동작하는 장애복구 및 분산 멀티티어를 제공하는 자바 소프트웨어의 기능을 추가한 서버를 위한 플랫폼이다. 이전에는 J2EE라 불리었으나 버전 5.0 이후로 Java EE로 개칭되었다. (출처 : 위키피디아)
썬 마이크로시스템즈는 1997년 ISO/IEC JTC1 표준화 그룹, 그리고 나중에는 ECMA International 그룹과 접촉하여 정식 승인 받으려 했으나 곧 이 프로세스에서 철수 했다. 자바는 사실상 (de facto) 의 표준이며 자바 커뮤니티 프로세스(Java Community Process) 를 통해 관리가 된다.
썬 마이크로시스템즈는 자바의 대부분을 무료로 배포하였으나 오픈이 아닌 Proprietary 소프트웨어였다. 썬 마이크로시스템즈는 자바 엔터프라이즈 시스템같은 특정 라이선스를 팔아서 수입을 올렸다. 썬사는 자사의 개발용(소프트웨어 개발 키트 (SDK))과 개발용의 일부인 실행용 (자바 런타임 환경, JRE) 을 구분한다. 실행용에는 컴파일러, 유틸리티 및 여러 개발용 헤더 파일이 포함되어 있지 않다.
2006년 11월 13일 썬 마이크로시스템즈는 대부분은 자바를 GPL 라이선스로 소스를 오픈하였으며 2007년 5월 8일 이 과정을 마쳤다. 썬 마이크로시스템즈가 권한을 가지고 있지 않은 대부분의 코어 부분을 오픈하였다.
2009년 4월 20일 제작사인 썬 마이크로시스템즈가 오라클과 인수합병됨에 따라 자바에 대한 권리 및 유지보수 또한 오라클로 넘어가게 되었다.
2. 자바의 발전
자바의 버전은 보통 Java SE 또는 JDK/JRE의 버전으로 말한다.JDK(Java Development Kit)는 표준 라이브러리를 포함하며, JDK 버전이 바뀜에 따라 이 라이브러리가 확대되고 API가 바뀐다.초기 1.0/1.1 버전에서 JDK/JRE의 명칭을 사용하다가 Java 1.2가 발표되면서 J2SDK/J2RE라고 개명하여 사용했으나 기존의 명칭으로 사용하는 사람들이 많아 현재는 다시 JDK/JRE의 명칭으로 돌아왔다.또한 J2SE(Java2 Standard Edition)라는 명칭 또한 Java SE(Java Standard Edition)으로 변경하였다.또한 버전체계의 메이저 버전(소숫점 위)이 계속 1.x로 고정되어 마이너 업데이트로 여기는 경우들이 있어 1.5 버전부터 5.0(1.5), 6.0(1.6)의 형태로 제품 버전을 코드버전과 별개로 발표하고 있다.
언어 자체는 자바언어명세(Java Language Specification, JLS)에서 정의되며 판(edition)으로 구분한다. JDK가 확장되는 동안 언어는 2판에서 거의 변화가 없었으나, JDK 5와 함께 바뀐 JLS 3판에서 제네릭(generic) 타입, 애너테이션(annotation) 같은 기능이 도입되면서 상당히 바뀌었다.JDK 7에서는 자바 언어에 상당한 변화가 계획되어 있었으나 JDK 7로 예정되었던 변화가 JDK 7와 JDK 8으로 나눠지면서 JDK 7에는 상대적으로 사소한 언어 특성만이 추가되었다. 구체적으로 이진수 표기 추가, 가독성을 위해 수 표기에 밑줄(underscore)을 허용, 스위치 문(switch에서 문자열 사용, 제네릭 타입 객체 생성 시 타입 추론(type inference), 자동 자원 해제를 위한 try 문법, 여러 예외 타입을 동시에 잡도록 허용하는 문법 등이 추가되었다.현재 자바언어는 JLS 3판, JDK는 버전 7이다.
JLS 1판
JLS 2판 :JDK 1.4: assertion 기능 추가
JLS 3판 : JDK 5
3. 자바언어의 특징
1) 자바 언어는 C/C++ 언어에서 문법을 차용해서 C/C++ 개발자를 흡수하고,개발 진입장벽을 낮춘 언어이다. 프로그램의 개념적인 내용은C/C++ 언어가 아니라 스몰토크(small talk)의 영향을 받았다. 그리고 C++의 복잡하고 난해한 문법은 모두 삭제하거나 변경하여 언어의 폭잡성을 대폭 낮췄다. C++에서 지원하는 포인터의 개념을 레퍼런스 개념으로 대처하도록 유도한다.
2) 자바의 가장 독특한 특징은 JVM이란 장치를 가지고 있다. C언어는 컴파일된 결과가 운영체제와 통신을 하지만, 자바는 가상의 운영체제인 JVM과 통신하게 된다. 자바는 JVM과 통신이 가독하도록 컴파일을 수행하고 JVM은 코드를 해석해서 운영체제와 통신한다. 이러한 운영형태는 C/C++에 비해서 실행 속도가 느리다는 단점이 있지만, JVM 덕분에 운영체제에 독립적인 실행이 가능하다. 또한 메모리 제어가 불가능하기 때문에 하드웨어에 직접적인 접근이 약간 어렵다는 단점이 있고, 메모리 제어가 불가능하기 떄문에 C언어의 고질적인 단점인 포인터 연산에 의한 오류가 일어나지 않는다.

JAVASOFT SHIPS JAVA 1.0
JAVASOFT SHIPS JAVA 1.0
Programming environment available free for developers
Palo Alto, CA - January 23, 1996 - JavaSoft, the newly-formed operating company of Sun Microsystems, Inc., today announced that the Java™ 1.0 programming environment is now available for download at http://java.sun.com.
"Java's write-once-run-everywhere capability along with its easy accessibility have propelled the software and Internet communities to embrace it as the de facto standard for writing applications for complex networks," said Alan Baratz, JavaSoft's newly appointed president. "We're delighted to invite developers to download Java 1.0 immediately and start building the next killer application."
"Improving Java to create this strong 1.0 general release has been a great achievement for our team," said Ruth Hennigar, general manager of Java language and applications, JavaSoft. "Since our first alpha release to the web in March we have received a lot of developer feedback and have improved functionality and reliability. This release incorporates the components that software developers have told us they need -- the Java Applet Viewer for running and testing applets; the Java Compiler; a prototype debugger and the Java Virtual Machine to run Java-based programs. We've also included class libraries for graphics, audio, animation and networking."
Since its announcement in May 1995, Java has been widely used to create hundreds of "applets" or small applications which can be downloaded across a network and can run locally. Companies as perse as National Semiconductor, Precision Systems, Inc. and Starwave have already announced significant Java-based programs.
Available for free over the Internet
Developers will continue to have access to Java 1.0, free of charge. It is available for download at http://java.sun.com. In addition, a number of companies have licensed the Java source code to enhance their browsers, create development tools for Java programming, and to port the Java Virtual Machine to various operating systems. To date, 15 companies, including IBM, SGI, Netscape, Oracle and Toshiba have licensed Java Source, and Microsoft has announced that it intends to license Java.Java 1.0 is available for the Windows 95 and NT on Intel® and Solaris™ on SPARC™ platforms today. Java 1.0 for Mac OS 7.5 is expected by the end of the first quarter of 1996.
"JavaSoft has targeted these four platforms that are all critical to Java's success," said Ruth Hennigar. "In addition, ports to other significant operating systems are underway outside of JavaSoft. For example, IBM has announced it would build ports for Microsoft Windows 3.1 and OS/2, and OSF has announced that it will build ports for additional versions of the UNIX® operating system."
Java-based applications are platform-independent; only the Java Virtual Machine needs to be ported to each platform. It acts as an interpreter between an end user's computer and the Java-based application. An application written in the Java environment can run anywhere, ending the need for porting applications to multiple platforms. The Java Virtual Machine is currently available to end users through JavaSoft's HotJava™, Netscape Navigator 2.0™ web browsers and will be available in Oracle's PowerBrowser™ and Spyglass' Mosaic™ browsers.
JavaSoft, headquartered in Palo Alto, is an operating company of Sun Microsystems Inc. The company's mission is to develop, market and support the Java technology and products based on it. Java supports networked applications and enables developers to write applications once that will run on any machine. JavaSoft develops applications, tools and systems platforms to further enhance Java as the programming standard for complex networks such as the Internet and corporate intranets.

- Robust new features including JDBC[tm] for database connectivity, RMI for remote object access, and additional Java Security APIs
- Global language support based on Unicode 2.0 standards
There has been an enormous amount of discussion in the media in the last few weeks regarding Microsoft's AFC. A few key points have been buried in the dialogue, and we'd like to resurface them.
First, Microsoft's AFC might have been a good improvement on the AWT in Sun's JDK 1.0.2, but the new JDK 1.1 AWT -- which ships today -- is an even more dramatic step forward in Java foundation classes. If Microsoft would like to compete against our last generation product, they're welcome to. We're moving on, and we suggest our developers do too.
Second, Microsoft's AFCs won't ship until May. JDK 1.1 with the new AWT is available today. Now. Download it at http://java.sun.com/products/jdk/1.1 and see how much stronger it is.
Third, Of course we're happy to see Microsoft becoming converted to cross platform technology. We invite Microsoft to submit them to the 100% Pure Java test at that time.
Developers can look to JavaSoft for the technologies they need to create any and all groundbreaking Java applications.

Sun Ships New Version of Java Platform
Sun Ships New Version of Java Platform
Over 100 New Features Set J2SE 5.0 for Next Generation of Java Developers
SANTA CLARA, Calif. - September 30, 2004 - Sun Microsystems, Inc. (Nasdaq: SUNW), the creator and leading advocate of Java(tm) technology, today announced the general availability ofJava 2 Platform Standard Edition (J2SE(tm)) 5.0. As one of the largest-scale projects developed through theJava Community Process(sm) (JCP(sm)), J2SE 5.0 involved nearly 160 expert members designing over 100 features that drive extensive developer benefits including ease of use, overall performance and scalability, system monitoring and management, and rich client desktop development. Easier to use with record breaking performance and quality, J2SE 5.0 is being heralded as the most significant upgrade to the Java platform and programming language in nearly a decade.
"J2SE 5.0 is delivering greatly improved developer productivity and outstanding quality by relying on the deep values of the Java language," said Graham Hamilton, vice president, Sun fellow and lead architect for the J2SE 5.0 release. "Working through 15 Java Community Process expert groups, the Java community has delivered the most significant update ever to the Java platform. It sets the stage for the next wave of network systems innovation."
Java Evolves to Meet Emerging Needs of Programmers and Applications
J2SE 5.0 is derived from the work of 15 component Java Specification Requests (JSRs) encompassing advanced capabilities for the language and platform. Industry leaders participating in the J2SE 5.0 expert group include Apache Software Foundation, Apple Computer, BEA Systems, Borland Software Corporation, Cisco Systems, Fujitsu Limited, HP, IBM, Macromedia, Nokia Corporation, Oracle, SAP AG, SAS Institute, SavaJe Technologies and Sun Microsystems. Highlights of the new Java platform include:
- Ease of development: Java language programmers can be more efficient and productive with new Java language features that enable faster and more secure coding. Generics, enumerated types, metadata and autoboxing of primitive types enable easier and faster coding.
- Monitoring and management: A key focus for the new platform release, the Java Virtual Machine and Java technology-based applications can be monitored and managed with the built-in support for Java Management Extensions. This helps ensure your employees', customer's and partner's systems stay up and running longer. Support for SNMP-based enterprise management systems is also viable.
- Rich client desktop: A new, more modern default Java technology-based application look and feel provides an up-to-date GUI for Java technology-based applications. J2SE 5.0 has full internationalization support and also features support for hardware acceleration via the OpenGL(R) API for Linux and Solaris(tm) operating systems.
- Greater Performance and scalability: The new release includes performance improvements such as faster startup time, a smaller memory footprint, and JVM auto-tuning to drive greater overall application and development performance on J2SE 5.0 over previous versions.
"In accord with the increasingly open Java Community Process policies and guidelines, several major components of J2SE 5.0 were conceived and led by members of the Java development community," said Doug Lea, professor at the State University of New York, Oswego. "All 15 component JSRs had plenty of community involvement, leading to more advice, feedback, review, testing and midcourse improvements than ever before in a major Java platform release. As specification lead for the Concurrency Utilities specification, it's great to see the results of all these component JSRs efficiently coordinated and available in J2SE."
"Above all else, this is a developer-focused release. When the Java platform was introduced by James Gosling and his team in 1995, it took off like a rocket because it struck a chord with developers A? and J2SE 5.0 is building on that legacy," said Joshua Bloch, specification lead for new language features (JSR-201), metadata (JSR-175) and author ofEffective Java(Addison Wesley, 2001). "I've had the good fortune to use the new features for the last year-and-a-half in the course of their development. I find them a joy to use and I have every confidence that other developers will too."
The Java technology platform's leadership and impact on innovation in the network computing industry is undisputed. The J2SE platform is the foundation platform for delivering Java on the desktop and throughout the enterprise. Over the course of both beta phases for the release, over a half million downloads of the Java Runtime Environment (JRE) and Software Development Kit (SDK) have signaled tremendous interest in the Java platform among developers.
The installed base of Java-based technology users continues to dominate in the enterprise and on the desktop with an estimated 150 million downloads of J2SE since its availability in December 1998. Additionally, nine out of the 10 leading PC manufacturers, cumulatively representing over 60 percent of the PC market, are now factory-installing the Java Runtime Environment on their systems. These manufacturers include Acer, Apple, Dell, Gateway, HP, Fujitsu-Siemens, Samsung, Tsinghua Tongfang and Toshiba.
"Beyond the technical improvements delivered by J2SE 5.0 over its predecessors, we were pleased to observe tight collaboration across the community in the development of this new platform," said Geir Magnusson Jr., The Apache Software Foundation's JCP SE/EE Executive Committee member. "Inpidual, academic, open source and corporate entities have worked together to deliver what is now the best Java Platform the Java development community has ever seen," added Pier Fumagalli, The Apache Software Foundation's representative on the J2SE Expert Group. "This is a major step in the right direction, and we are looking forward to even broader community participation and process transparency for J2SE 6."
"J2SE 5.0 is the culmination of many years' work and a major step forward for the Java community" said George Paolini, Vice President and General Manager of Borland's Developer Tools Business Unit. "Enterprises around the globe will benefit from the ability to extend legacy systems through its implementation of web services and be able to integrate heterogeneous environments much more easily than before. Borland's Jbuilder 2005 is among the first Java development tools to fully support J2SE 5.0. and make this a reality."
In conjunction with todayA?s news, Zero G Software announced that it is the first to deliver full installer support for J2SE 5.0. Users of InstallAnywhere from Zero G, the de facto standard for multiplatform software deployment and delivery and the most widely used installer authoring tool for Java-enabled software, will reap the benefits of the newest Java features including the ability to bundle the J2SE virtual machine with installers, and have their applications use J2SE 5.0. The integration of J2SE 5.0 functionality also provides InstallAnywhere users with a significant increase in installer and build performance.
"InstallAnywhere has always been the first to support the latest innovations in Java technology," said Eric N. Shapiro, CEO at Zero G Software. "Working with Sun, we are continuing our commitment to provide customers with the latest technologies to improve the software installation process by integrating support for J2SE 5.0, and jump-starting its adoption by the thousands of developers who use InstallAnywhere for deploying Java-based applications."
