Description: BeanShell是一个小型的，免费的，可嵌入式的，具有面向对象脚本语言特性的Java代码解释器。它是用Java语言写的。它能执行标准的Java语句和表达式，还自带简单的脚本命令和语法。它把编程对象当成一个简单的方法，这很像Perl和JavaScript.
你可以在写Java测试或调试时使用BeanShell，也可以用它作为你的应用程序的脚本引挚。简而言之，BeanShell可以动态的解释JAVA语言。也就是说BeanShell在许多方面对于Java的用处就像Tcl/Tk对于C的用处一样：BeanShell是可嵌入式的---你可以在运行时从你的应用程序调用BeanShell去动态的执行Java代码或是为你的应用程序提供脚本扩展。相反，你也可以从BeanShell调用你的应用程序及其对象，它可以让JAVA对象和API动态运行。正因为BeanShell是用JAVA写的，所以它可以和你的应用程序运行在同一个JVM空间内，你也可以自由的传递实时对象的参照(References)到脚本代码中并且作为结果返回。-BeanShell is a small, free of charge, to be embedded with object-oriented scripting language features of Java code interpreter. It is written in the Java language. It implementation of the standards Java language and expression, also own simple script commands and syntax. Programming Object put it as a simple method, much like Perl and JavaScript. You can write Java testing or debugging use BeanShell can also use it as your application's scripting engine. In short, the dynamics of BeanShell can explain Java language. BeanShell is in many respects for the usefulness of Java as Tcl / Tk for the usefulness of the same C : BeanShell can be embedded -- you can run from your application to BeanShell called dynamic execution of Java code, or for your application for extension of the script.

Description: 使用spring构建一个简单的工作流引擎，便于初学者了解工作流引擎的开发模式。-The API discussed here is bundled as the main source code under the src/java directory.
Three unit tests exist in the src/testdirectory including
SimpleSequenceTestCase, RateDropTestCase and PoolingTestCase.
To run all the tests type "maven test" in a command shell and Maven will download
all the necessary jar files before compiling and running. To see all output in the console,
set maven.junit.usefile=false in the build.properties file. Otherwise, use all JUnit test
output will be logged to the files under the target/test-reports dirctory.
Actual XSL transforms will take place for two of the tests with results piped to output via log4j.
After successful execution of the test suite, you may wish to run the tests individually and watch
output real time. Try using "maven test:ui" to pull up the graphical test
runer, the select the test you want to run and watch the output in the console.

Description: This example shows the ability of Java to declaratively restrict access to certain packages when run with SecurityManager.
By default, access to classes in "sun.*" packages is restricted. However, since Java runs without SecurityManager by default, these checks may not be always performed.
An explanation of example:
1. RestrictedPackageAccess class creates and calls sun.misc.BASE64Encoder
2. First, the default execution happens without SecurityManager, and everything is permitted
3. Secondly, SecurityManager is enabled, and the code doesn t pass the security check
4. However, when the code is run with a different policy, that allows access, the excution goes fine again. Platform: |

马萨诸塞州技术学院的一篇论文，共21页，本文讨论了JAVA支持参数多态性，描述了执行机制
-This paper extends Java in one area where more power is
needed: support for parametric polymorphism,which allows
the defi nition and implementation of generic abstractions.
The paper discusses both the rationale for our design
decisions and the impact of the extension on other parts
of Java, including arrays and the class library. It also
describes an implementation of the mechanism, including
extensions to the Java virtual machine, and designs for the
bytecode verifi er and interpreter. The bytecode interpreter
has been implemented it provides good performance for
parameterized code in both execution speed and code
size, and does not slow down programs that do not use
parameterized code. Platform: |

Description: This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.

Description: 由于嵌入式系统多数为实时系统，传统Java技术应用于嵌入式系统的主要不足之处表现为：由于Java虚拟机是在运行中对引用到的类进行动态装载、解析和连接，影响了系统的实时性；垃圾收集器(GC)的自动运行导致了任务执行时间的不可预测性；另外，Java语言规范和Java虚拟机规范讨论线程调度的地方非常笼统，导致在不同虚拟机实现中线程调度特性表现不一致。-Because embedded systems mostly real-time systems, Java technology in embedded systems traditionally the main shortcomings were as follows: As the Java virtual machine is running the classes of the reference to dynamic loading, analysis and connectivity, affected the system real-time garbage collector (GC) to run automatically lead to a job execution time unpredictability addition, Java Language Specification and Java Virtual Machine specification where the discussion thread scheduling is very general, leading to virtual machine implementations in different thread scheduling features inconsistent performance.

Description: 异常指的是程序运行时出现的非正常情况，又称为差错、违例等。在上一节中介绍的运行错误就是异常的主要现象。当异常现象发生时，会造成程序运行中断、系统死机等问题。Java程序可以用特定语句来处理异常并继续程序执行，而不让程序中断。Java语言提供一个异常处理类Exception类，专门处理程序执行期间的错误。每当Java程序运行过程中发生一个可识别的运行错误时，即该错误有一个异常类与之相对应时，系统都会产生一个相应的该异常类的对象，即产生一个异常。Java语言异常处理机制有以下一些优点
-Abnormal refers to the program running when the abnormal situation of, also known as discrepancies, violations, etc. In the previous section of the mistake is abnormal operation introduced the main phenomenon. When abnormal phenomenon occurs, can cause to run the program interrupt, system crash. Java program can use specific statements to deal with problems and continue program execution, and don t let the interruption of the program. Java language provides a Exception handling class Exception classes, special processing program during the execution of mistakes. Whenever Java program running occurred in the process of identification of a runtime error, the wrong when there is an exception class and the relative, the system will generate a timely corresponding the abnormal objects of a class, which produce an exception. Java language exception handling mechanism has the following some advantages
