With this new implementation, the code throws an exception if LastName is assigned an invalid value, either from another member of the same class or via a direct assignment to LastName from inside ProgramMain() The ability to intercept an assignment and validate the parameters by providing a field-like API is one of the advantages of properties4 It is a good practice to only access a property-backing field from inside the property implementation In other words, always use the property, rather than calling the field directly In many cases, this is true even from code within the same class as the property If following this practice, when code such as validation code is added, the entire class immediately takes advantage of it (As described later in the chapter, one exception to this occurs when the field is marked as read-only because then the value cannot be set once class instantiation completes, even in a property setter) Although rare, it is possible to assign a value inside the setter, as Listing 519 does In this case, the call to valueTrim() removes any whitespace surrounding the new last name value

If you supply multiple interfaces or class constraints for a type parameter, the compiler always assumes an AND relationship between constraints For example, where TKey : IComparable, IFormattable requires that both IComparable and IFormattable are supported There is no way to specify an OR relationship between constraints Hence, an equivalent of Listing 1128 is not supported

Read-Only and Write-Only Properties By removing either the getter or the setter portion of a property, you can change a property s accessibility Properties with only a setter are writeonly, which is a relatively rare occurrence Similarly, providing only a getter will cause the property to be read-only; any attempts to assign a value will cause a compile error To make Id read-only, for example, you would code it as shown in Listing 520

public class BinaryTree<T> // Error: OR is not supported where T: SystemIComparable || SystemIFormattable<T> { }

class Program { static void Main() { Employee employee1 = new Employee(); employee1Initialize(42); // ERROR: Property or indexer 'EmployeeId' // cannot be assigned to -- it is read-only employee1Id = "490"; } } class Employee { public void Initialize(int id) { // Use field because Id property has no setter, // it is read-only _Id = idToString(); } // // Id property declaration public string Id { get { return _Id; } // No setter provided } private string _Id; }

Listing 520 assigns the field from within the Employee constructor rather than the property (_Id = id) Assigning via the property causes a compile error, as it does in ProgramMain()

features will be familiar with the concept of delegates, which are covered in 13 One additional constraint that is not allowed is the use of any delegate type as a class constraint For example, the compiler will output an error for the class declaration in Listing 1129

In general this set of seven methods will form the core of the events that you are interested in Be careful when typing screen updates to user events to ensure that you make the most efficient use of the paint and update methods The flow of events, particularly with those related to mouse motion, can be so fast that the screen updates will cause the applet to flicker While it is possible to override the handleEvent class you should consider if it is essential before doing so 1035 Adding event handling to HelloWorld To demonstrate the event methods, we ll extend the HelloWorld class to have two extra features When the mouse moves over the area of the applet, we ll have the string move with the cursor, and when the user presses a key, we ll append the key character to the string The code to do this is: import javaawtGraphics; import javaawtColor; import javaawtEvent; public class HelloWorld extends javaappletApplet { int sx,sy; // The coordinates of the string StringBuffer hw;// The string to display public void init() { sx = 5; sy = 20;
