// get the additional info IDictionary d = ex.Data; foreach (object o in d.Keys) { Console.WriteLine("Info: {0} = {1}", o, d[o]); } } // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } The catch clause of the inner try statement in the example handles a NullReferenceException, adds some additional data, and rethrows the exception. The modified exception is then handled by the outer try statement, which also has a handler for NullReferenceException and which prints out the additional data. There is no convention for the use of the name/value pairs, but you should try to provide information useful to someone trying to figure out why the exception was thrown. The IDictionary returned by the Data property can be modified by exception handlers, so you should not rely on the contents being secure or immutable. Compiling and running the code in Listing 14-16 produces the following results: Outer Info: Info: Press try statement - Exception handled: System.NullReferenceException Additional Information = This is some helpful state info More Information = This is some extra helpful state info enter to finish

There are a lot of ready-made exception classes in the .NET class library, but sometimes you will need to create an exception class that is specific to your program. You can easily do this by deriving from System.Exception.

You also have more control over the resource bundle cache On a smaller scale, there are some smaller-scale changes The Arrays class has new methods for making copies; the Collections class has new support methods; Scanner gets a method to reset its delimiters, radix, and locale; and Calendar gets new methods to avoid using DateFormat for getting the display name of a single field One last aspect of javautil worth mentioning was first explored in 1 The javautilspi and javatextspi packages take advantage of a new service provider lookup facility offered by the Service class Without knowing it, you saw how to configure the service via the provider configuration file found under the META-INF/services directory In javautilconcurrent, you ll find concurrent implementations for Deque and NavigableMap In addition, the Future interface has been extended with Runnable to give you a RunnableFuture or RunnableScheduledFuture.

Earlier versions of .NET included a convention that the exception classes included in the System namespace would derive from System.SystemException, while non-Microsoft programmers would derive their exceptions from System.ApplicationException. This convention has been dropped, and you should derive your exceptions directly from System.Exception or from another custom exception type. You can still see the earlier convention in the way that some of the built-in exceptions use

1. Compute the lifetime value, after 3 years, of newly acquired customers given these facts: 400,000 customers; retention rates 62 percent, 70 percent, 74 percent; average purchase $320,

Listing 14-17 demonstrates a custom exception class. Listing 14-17. Defining a Custom Exception Class class CustomException : Exception { public CustomException() : base() { } public CustomException(string message) : base(message) { } public CustomException(string message, Exception inner) : base(message, inner) { } } This is the simplest custom exception possible. It doesn t define any additional program-specific members. The value in this exception comes from the convention to use different exception types to represent different exception conditions. It follows the convention for a custom exception, which is a name that ends with Exception and the set of constructors shown. You can define additional constructors as required, but you should always include the three that are shown in the listing. Throwing a custom exception is just like throwing one of the system exceptions. You create a new instance and then use the throw keyword. catch clauses can be defined to handle your exception as normal; this is shown in Listing 14-18. Listing 14-18. Throwing and Catching a Custom Exception using System; class CalculationException : Exception { private int param1, param2; public CalculationException() : base() { } public CalculationException(string message) : base(message) { } public CalculationException(string message, Exception inner) : base(message, inner) { } public CalculationException(string message, int p1, int p2) : base(message) { param1 = p1; param2 = p2;
