电脑方面的吗??
Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.
The original and reference implementation Java compilers, virtual machines, and class libraries were developed by Sun from 1995. As of May 2007, in compliance with the specifications of the Java Community Process, Sun made available most of their Java technologies as free software under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java and GNU Classpath.
One characteristic of Java is portability, which means that computer programs written in the Java language must run similarly on any supported hardware/operating-system platform. One should be able to write a program once, compile it once, and run it anywhere.
This is achieved by compiling the Java language code, not to machine code but to Java bytecode – instructions analogous to machine code but intended to be interpreted by a virtual machine (VM) written specifically for the host hardware. End-users commonly use a Java Runtime Environment (JRE) installed on their own machine for standalone Java applications, or in a Web browser for Java applets.
Standardized libraries provide a generic way to access host specific features such as graphics, threading and networking. In some JVM versions, bytecode can be compiled to native code, either before or ring program execution, resulting in faster execution.
A major benefit of using bytecode is porting. However, the overhead of interpretation means that interpreted programs almost always run more slowly than programs compiled to native executables would, and Java suffered a reputation for poor performance. This gap has been narrowed by a number of optimization techniques introced in the more recent JVM implementations.
One such technique, known as just-in-time (JIT) compilation, translates Java bytecode into native code the first time that code is executed, then caches it. This results in a program that starts and executes faster than pure interpreted code can, at the cost of introcing occasional compilation overhead ring execution. More sophisticated VMs also use dynamic recompilation, in which the VM analyzes the behavior of the running program and selectively recompiles and optimizes parts of the program. Dynamic recompilation can achieve optimizations superior to static compilation because the dynamic compiler can base optimizations on knowledge about the runtime environment and the set of loaded classes, and can identify hot spots - parts of the program, often inner loops, that take up the most execution time. JIT compilation and dynamic recompilation allow Java programs to approach the speed of native code without losing portability.
Another technique, commonly known as static compilation, or ahead-of-time (AOT) compilation, is to compile directly into native code like a more traditional compiler. Static Java compilers translate the Java source or bytecode to native object code. This achieves good performance compared to interpretation, at the expense of portability; the output of these compilers can only be run on a single architecture. AOT could give Java something close to native performance, yet it is still not portable since there are no compiler directives, and all the pointers are indirect with no way to micro manage garbage collection.
Java's performance has improved substantially since the early versions, and performance of JIT compilers relative to native compilers has in some tests been shown to be quite similar.[12][13] The performance of the compilers does not necessarily indicate the performance of the compiled code; only careful testing can reveal the true performance issues in any system.
One of the unique advantages of the concept of a runtime engine is that even the most serious errors (exceptions) in a Java program should not 'crash' the system under any circumstances, provided the JVM itself is properly implemented. Moreover, in runtime engine environments such as Java there exist tools that attach to the runtime engine and every time that an exception of interest occurs they record debugging information that existed in memory at the time the exception was thrown (stack and heap values). These Automated Exception Handling tools provide 'root-cause' information for exceptions in Java programs that run in proction, testing or development environments. Such precise debugging is much more difficult to implement without the run-time support that the JVM offers.

Ⅵ JAVA 英文介绍
你直接打开www.sun.com 那是对java 介绍的最详细,最专业的资料,找中文翻译嘛,你就下载些什么金山词霸了什么著名软件啊。其实JDK1.5就是带有中文版的,不过不是介绍发展的,而是介绍java中的类,属性,方法。你自己想想该怎么办?java可广了,包括java,j2ee,jsp它和microsoft在斗争,microsoft的.net和广义的java只会向前发展决不会有落伍的一天,你不用谢我,大家都是搞软件的嘛!
Ⅶ java对英语要求高吗
作为一个java工程师来说。以下是我心得,希望帮到想做java的人,不要被骗;
如果你的英语不好,老师和培训机构的会告诉你,不会英语没关系,可以学编程,作为过来人我告诉你,就是扯蛋。他们是为赚钱,才不会管你后面的就业问题。
都说Java不会英语那就是扯蛋 ,我和同事们都深深的感受到了,你不认识那个单词,代码的什么东西根本记不住,你知道逻辑,你写不出来,英语别人写的代码你都不知道写的啥,你写的出来代码 ?就算是搞了10年的Java的人,他只会中文和英语,你让他用韩国或者日本的语言来写个代码,照样屁都放不出来一个。所以没有一定的英语底子,不要搞编程,因为你会后悔。就算是搞,你也只能是学个基础,不适合长远发展。
