Introduction 在编写代码过程中,我们会从基础的C语言开始学起,然后逐步进阶,而JAVA虽然比C语言稍微进阶一些,但仍然是一门基础性的编程语言。 As we write code, we start with the basic C language and work our way up. JAVA is a little bit more advanced than C, but its still a basic programming language. Java 是由 Sun Microsystems 公司于1995年 5月推出的 Java 面向对象程序设计语言和 Java 平台的总称。由 James Gosling和同事们共同研发,并在1995年正式推出。后来 Sun 公司被 Oracle (甲骨文)公司收购,Java 也随之成为 Oracle 公司的产品。 Java is the umbrella term for Java object-oriented programming language and Java platform launched by Sun Microsystems in May 1995. Developed by James Gosling and colleagues, it was launched in 1995. Sun was later acquired by Oracle (ORCL), and Java became an Oracle product. Java分为三个体系:JavaSE(J2SE)(Java2 Platform Standard Edition,java平台标准版)JavaEE(J2EE)(Java 2 Platform,Enterprise Edition,java平台企业版)JavaME(J2ME)(Java 2 Platform Micro Edition,java平台微型版) Java is divided into three systems:JavaSE (J2SE)(Java2 Platform Standard Edition, java Platform Standard Edition)JavaEE(J2EE)(Java 2 Platform,Enterprise Edition, java Platform Enterprise Edition)JavaME(J2ME)(Java 2 Platform Micro Edition, java Platform Micro Edition)在2005年 6月,JavaOne 大会召开,SUN 公司公开 Java SE 6。此时,Java 的各种版本已经更名,以取消其中的数字”2″:J2EE 更名为 Java EE,J2SE 更名为Java SE,J2ME 更名为 Java ME。 In June 2005, at the JavaOne conference, SUN unveiled Java SE 6. By this time, the various versions of Java had been renamed to remove the number “2”: J2EE was renamed Java EE, J2SE was renamed Java SE, and J2ME was renamed Java ME.三、发展历史三. Development History JAVA的发展历史较短,二十几年的历程,将其从一个不成熟的编程语言逐渐成为一门体系完整的编程语言。 The development history of JAVA is relatively short, more than 20 years, from an immature programming language gradually into a system of complete programming language.1995年 5月 23日,Java 语言诞生1996年 1月,第一个 JDK-JDK1.0诞生1996年 4月,10个最主要的操作系统供应商申明将在其产品中嵌入 JAVA 技术1996年 9月,约8.3万个网页应用了 JAVA 技术来制作1997年 2月 18日,JDK1.1发布1997年 4月 2日,JavaOne 会议召开,参与者逾一万人,创当时全球同类会议规模之纪录1997年 9月,JavaDeveloperConnection 社区成员超过十万1998年 2月,JDK1.1被下载超过2,000,000次1998年 12月 8日,JAVA2企业平台 J2EE 发布1999年 6月,SUN 公司发布 Java 的三个版本:标准版(JavaSE,以前是 J2SE)、企业版(JavaEE 以前是 J2EE)和微型版(JavaME,以前是 J2ME)2000年 5月 8日,JDK1.3发布2000年 5月 29日,JDK1.4发布2001年 6月 5日,NOKIA 宣布,到2003年将出售1 亿部支持 Java 的手机2001年 9月 24日,J2EE1.3发布2002年 2月 26日,J2SE1.4发布,自此 Java 的计算能力有了大幅提升2004年 9月 30日 18:00PM,J2SE1.5发布,成为 Java 语言发展史上的又一里程碑。为了表示该版本的重要性,J2SE1.5更名为 Java SE 5.02005年 6月,JavaOne 大会召开,SUN 公司公开 Java SE 6。此时,Java 的各种版本已经更名,以取消其中的数字”2″:J2EE 更名为 Java EE,J2SE 更名为 Java SE,J2ME 更名为 Java ME2006年 12月,SUN 公司发布 JRE6.02009年 04月 20日,甲骨文74亿美元收购 Sun,取得 Java 的版权。2010年 11月,由于甲骨文对于 Java 社区的不友善,因此 Apache 扬言将退出 JCP。2011年 7月 28日,甲骨文发布 Java7.0的正式版。2014年 3月 18日,Oracle 公司发表 Java SE 8。2017年 9月 21日,Oracle 公司发表 Java SE 92018年 3月 21日,Oracle 公司发表 Java SE 102018年 9月 25日,Java SE 11发布2019年 3月 20日,Java SE 12发布On May 23,1995, the Java language was bornIn January 1996, the first JDK-JDK1.0 was bornIn April 1996, ten major operating system vendors announced that they would embed JAVA technology in their productsIn September 1996, about 83,000 web pages were created using JAVA technologyOn February 18,1997, JDK1.1 was releasedOn April 2,1997, the JavaOne Conference was held with over 10,000 participants, which was then the largest conference of its kind in the worldIn September 1997, the Java Development Connection community had more than 100,000 membersIn February 1998, JDK1.1 was downloaded over 2,000,000 timesOn December 8,1998, the JAVA2 enterprise platform J2EE was releasedIn June 1999, SUN released three versions of Java: Standard Edition (JavaSE, formerly J2SE), Enterprise Edition (JavaEE, formerly J2EE), and Micro Edition (JavaME, formerly J2ME).On May 8,2000, JDK1.3 was releasedOn May 29,2000, JDK1.4 was releasedOn June 5,2001, NOKIA announced that it would sell 100 million Java-enabled mobile phones by 2003On September 24,2001, J2EE1.3 was releasedOn February 26,2002, J2SE1.4 was released, and since then Javas computing power has improved dramaticallyAt 18:00PM on September 30,2004, J2SE1.5 was released, becoming another milestone in the development history of Java language. In recognition of the importance of this release, J2SE1.5 was renamed Java SE 5.0In June 2005, at the JavaOne Conference, SUN unveiled Java SE 6. By this time, the various versions of Java had been renamed to remove the number “2”: J2EE was renamed Java EE, J2SE was renamed Java SE, and J2ME was renamed Java MEIn December 2006, SUN released JRE6.0On April 20,2009, Oracle bought Sun for $7.4 billion, acquiring Java rights.In November 2010, Apache threatened to quit JCP because of Oracles unkindness to the Java community.On July 28,2011, Oracle released the official version of Java7.0.On March 18,2014, Oracle announced Java SE 8.On September 21,2017, Oracle announced Java SE 9On March 21,2018, Oracle announced Java SE 10On September 25,2018, Java SE 11 was releasedOn March 20,2019, Java SE 12 was released 看了以上内容,相信你对JAVA语言已经有一定了解了,下面我们来看一个简单的案例。 After reading the above content, I believe you have a certain understanding of the JAVA language, lets look at a simple case.今天的分享就到这里了。如果您对今天的文章有独特的想法,欢迎给我们留言,让我们相约明天。祝您今天过得开心快乐!Thats all for todays sharing.
