to be be ported to a large number of platforms by simply outlining the functions of the byte-codes and leaving the implementation details to the software engineers Because the Java machine implements a set of logical or virtual services and devices, there is no need for the Java language to supply libraries for specific types of device (for example, network cards) or to cater for the internal dependencies of specific platforms (for example, byte ordering) The specification for the Java VM lays out the abstract specification and it is then the job of each implementer to translate this correctly The use of a VM provides a common development environment which is consistent across software and hardware systems, allowing both the developer and the user to deal with a single, common system and avoiding the complexities of moving between disparate platforms Java includes a full VM specification which is precise enough to outline what functions Java implementations should support, but also avoids specifying exactly how these functions should be implemented By leaving the details to the developers of the Java ports there is a greater scope for Java systems to take full advantage of client platforms without the restrictive influence of an overly detailed specification It also enables the developer to implement Java functions independently of Sun and allows the differentiation of commercial Java ports; this is sure to be good for the life of Java in the long run Is it a good idea to allow developers loose with something so important There are good and bad sides to this The bad side is that there is no guarantee that all of the features will be implemented correctly at least until some standard test suites are produced which facilitate exhaustive analysis But it is good that the specification is sufficiently open to encourage innovation and competition, two things which will benefit the Java community in the medium to long term The presence of such a thoughtful and open specification should also serve to allay fears that Sun wish to exclusively control the deployment and future of Java since, as the number of independent ports of the Java system increases, the amount of control that Sun and SunLabs can have on the language diminishes 1232 The downside of a virtual machine There are costs associated with using a virtual machine Firstly, if the VM is being designed to run across several platforms there is a tendency for the specification to gravitate towards the lowest common denominator For example, if the VM were initially intended to run on high-end 3-D workstations as well as low-end PCs, the specification will realistically have to dispense with the additional functionality offered by the workstations in favour of specifying a set of features which the PCs can implement as well after all, there is no value in a VM which is too restrictive in terms of requirements, because no one will implement a port Secondly, there is little scope for change or adapting new features into the VM As an example, the Java VM specification does not include any built-in support for 3-D graphics This effectively means that until the Java language is extended to support 3-D graphics in the core language set, Java cannot be effectively used for complex 3-D graphics applications Also, because the Java language and VM specifications will be implemented on a wide range of platforms, unless all platforms can support 3-D either the support will not be added or some platforms will no longer be supported by Java both of which would be far from ideal Native methods Java tries to solve this problem by supporting native methods Native methods are Java instance methods or class methods which are written in a language other than Java, for example C or C++ The native method is declared in the Java code and then developed in another language Dynamically loaded libraries are used to load the code into the Java environment space; the header files are generated for the target language from the Java code in order to facilitate the passing of arguments The advantage of using native methods is that it addresses the inherently static nature of the Java VM by allowing developers to write external code which can take advantage of new system features which were not incorporated in the Java language Native methods can also be used to access system libraries which may not be available to the Java system, perhaps accessing some system specific features that are not supported on other platforms Native methods can also be used to increase perform-.

If the calculation involves only constants, then the calculation will be checked by default The results of Listing 107 appear in Output 102

Status status = OnTemperatureChange(value);

OUTPUT 102:

Unhandled Exception: SystemOverflowException: Arithmetic operation resulted in an overflow at ProgramMain() in Programcs:line 12

Since OnTemperatureChange potentially corresponds to a chain of delegates, status reflects only the value of the last delegate All other values are lost entirely To overcome this issue, it is necessary to follow the same pattern that you used for error handling In other words, you must iterate through each delegate invocation list, using the GetInvocationList() method, to retrieve each individual return value Similarly, delegate types that use ref and out parameters need special consideration

In addition, depending on the version of Windows and whether a debugger is installed, a dialog may appear prompting the user to send an error message to Microsoft, check for a solution, or debug the application Also, the location information (Programcs:line X) will appear only in debug compilations compilations using the /Debug option of the Microsoft cscexe compiler The result is that an exception is thrown if, within the checked block, an overflow assignment occurs at runtime The C# compiler provides a command-line option for changing the default checked behavior from unchecked to checked C# also supports an unchecked block that truncates the data instead of throwing an exception for assignments within the block (see Listing 108)

There are two key problems with the delegates as you have used them so far To overcome these issues, C# uses the keyword event In this section, you will see why you would use events, and how they work

using System; public class Program { public static void Main() { unchecked {
