You cannot create class objects directly from a generic class. First, you need to tell the compiler what actual types should be substituted for the placeholders (the type parameters). The compiler takes those actual types and creates a template from which it creates actual class objects. To construct a class type from a generic class, list the class name and supply real types between the angle brackets, in place of the type parameters. The real types being substituted for the type parameters are called type arguments. Type arguments SomeClass< short, int > The compiler takes the type arguments and substitutes them for their corresponding type parameters throughout the body of the generic class, producing the constructed type from which actual class instances are created. Figure 19-4 shows the declaration of generic class SomeClass on the left. On the right, it shows the constructed class created by using the type arguments short and int.

corner with rounded edges, as shown in Figure 11-18. Mine is roughly 100 display units wide and 50 display units tall.

If the exception was raised in a section of code that was not guarded by a try statement, or if the try statement does not have a matching exception handler, the system will have to look further for a matching handler. It will do this by searching down the call stack, in sequence, to see whether there is an enclosing try block with a matching handler. Figure 11-7 illustrates the search process. On the left of the figure is the calling structure of the code, and on the right is the call stack. The figure shows that Method2 is called from inside the try block of Method1. If an exception occurs inside the try block in Method2, the system does the following: First, it checks to see whether Method2 has exception handlers that can handle the exception. If so, Method2 handles it, and program execution continues. If not, the system continues down the call stack to Method1, searching for an appropriate handler. If Method1 has an appropriate catch clause, the system does the following: Goes back to the top of the call stack which is Method2 Executes Method2 s finally block, and pops Method2 off the stack Executes Method1 s catch clause and its finally block If Method1 doesn t have an appropriate catch clause, the system continues searching down the call stack.

If the string cannot be parsed, the system raises an exception. There is another static method, TryParse, that returns true if the string was successfully parsed and false otherwise. It does not raise an exception if the parse fails.
