This chapter highlights the differences between applications and applets We decided to approach applications in this manner for two reasons: firstly, because a large number of similarities exist between writing an applet and writing an application a chapter covering a ground-up tutorial for application writing would duplicate a large amount of the material covered in the previous chapter Secondly, since most Java developers will start writing applets and only switch to applications when confronted by one of the limitations discussed in this chapter, we felt it made some sense to concentrate on applets initially, and then detail what other information is needed to write an application Having read the initial chapters especially the applet chapter ( 10) the information in this chapter should be sufficient to allow you to write an application with little difficulty The most important part of this chapter is the section that describes what an application can do that an applet cannot and, equally, what an applet can do that an application cannot This chapter should make clear that there are many similarities between applets and applications, and that one of the differences is the lack of external calls which are provided for applets by a browser We have also introduced the notion of code that will execute as both an applet and an application and made clear the advantages and disadvantages that this technique involves Finally, we described the additional information required to use AWT elements and threads in an application Although the same libraries are used in both applets and applications, applications require some glue code which compensates for the lack of external messages and inheritance which is implicit with an applet At the end of this chapter you should be aware that applications written in Java embody much of the flexibility of an applet, but do not incur the same security limitations that are required for applets However, this developmental freedom comes at the price of losing the ability for a Java-compatible browser to load Java code dynamically and execute it By writing applications you must arrange to have the user download the compiled application beforehand; users would typically expect to have access to the source code if the code is not commercial or is unsupported However, applications written in Java will be developed and, while possibly not as attractive to developers as writing applets, application development can produce powerful and flexible code using the Java package libraries allied with the cross-platform support that Java provides as a function of using byte-codes.

ADVANCED TOPIC Lazy Loading with Generics and Lambda Expressions Starting with NET Framework 40, a new class was added to the CLR to assist with lazy initialization: SystemLazy<T> Listing 925 demonstrates how to use it

using SystemIO; class DataCache { // public string FileStreamName { get; set; } public DataCache() { _FileStream = new Lazy<TemporaryFileStream>( () => new TemporaryFileStream(FileStreamName)); } public TemporaryFileStream FileStream { get { return _FileStreamValue; } } private Lazy<TemporaryFileStream> _FileStream; // }

public class Thermostat { public float CurrentTemperature { get{return _CurrentTemperature;} set { if (value != CurrentTemperature) { _CurrentTemperature = value; // INCOMPLETE: Check for null needed // Call subscribers OnTemperatureChange(value); } } } private float _CurrentTemperature; }

The SystemLazy<T> class takes a type parameter (T) that identifies what type the Value property on SystemLazy<T> will return Instead of assigning a fully constructed TemporaryFileStream to the _ FileStream field, an instance of Lazy<TemporaryFileStream> is assigned (a lightweight call), delaying the instantiation of the TemporaryFileStream itself, until the Value property (and therefore the FileStream property) is accessed If in addition to type parameters (generics) you use delegates, you can even provide a function for how to initialize an object when the Value property is accessed Listing 925 demonstrates passing the delegate, a lambda expression in this case, into the constructor for SystemLazy<T> It is important to note that the lambda expression itself, () => new TemporaryFileStream(FileStreamName), does not execute until Value is called Rather, the lambda expression provides a means of passing the instructions for what will happen, but not actually performing those instructions until explicitly requested

Now the assignment of CurrentTemperature includes some special logic to notify subscribers of changes in CurrentTemperature The call to notify all subscribers is simply the single C# statement, OnTemperatureChange(value) This single statement publishes the temperature change to the cooler and heater objects Here, you see in practice that the ability to notify multiple subscribers using a single call is why delegates are more specifically known as multicast delegates
