Java Web Services: Integrating Web Services with a Database
Price on Request
1 hour 55 minutes
SOAP-based web services for Java applications offer a standardized and scalable means to communicate with external applications. In this course, you'll build a SOAP-based web service app for a fictitious book store that will enable client apps to view, add, update, and delete books whose details are stored in a database. Begin by defining a Book class whose instances can be transmitted between applications using the SOAP protocol. Then, integrate a MySQL database with the web services app and load it with data that will be made accessible to client applications using CRUD techniques. Lastly, host your web service application in a production environment by deploying it to an Apache Tomcat web server. When you're done, you'll know how to use the SOAP protocol to enable client apps to interact with a remote database.

Java: Getting Started with Reflection
Price on Request
1 hour 55 minutes
Reflection is a popular programming technique that accesses and modifies class and object information at runtime. Reflection is available in many programming languages, but Java has an especially powerful set of reflection APIs that reflect - no pun intended - the emphasis that Java lays on type safety. Learn how to access a Java class object. Use reflection APIs to view class fields, constructors, and methods. Create objects for various built-in classes and use reflection to view the class of an object. Investigate the significance of the fully qualified name of a class and how you can use the .forName() method from the built-in class java.lang.Class. Use this method to obtain variables of primitive types and arrays of differing dimensionality. Then use reflection to access modifiers applied to member fields. Upon completion, you'll be able to use reflection in your Java operations with confidence.

Annotations on Java code allow you to associate additional metadata with classes, member variables, constructors, and methods. These annotations can be used to perform additional checks or add functionality to your Java code. Use this course to practice using annotations with reflection. Work with both built-in and custom annotations and see how you can access the annotations applied on classes, fields, and methods. Learn why not all annotations can be accessed via reflection. Create your own custom annotation and experiment with various retention policies. Next, examine accessing generics and arrays with reflection.

Pointers and References in C++: Allocating Memory with New & Delete Operators
Price on Request
1 hour 25 minutes
C++, like C, has powerful support for memory allocation and deallocation. In the world of C, these operations are performed using malloc() and free(), which are not to be used in the C++ world. In classic C++, memory allocation and deallocation are performed using the new and delete operators. You will begin this course by understanding the new and delete keywords, and note how these lead to the invocation of the underlying constructors and destructors on whatever objects are being worked with. In contrast, the C versions, that is, malloc() and free(), do not invoke constructors or destructors. You will then move on to the use of array new and array delete, which is how the new and delete followed by square brackets are referred to. Finally, you will look at the differences between const pointers and pointers to consts.
