The Java EE server will assist the developer in configuring the component at deployment and runtime automatically. Instead, developers enter the information in the form of an annotation directly into a Java source file. Since the Java EE version 5, the XML Deployment descriptors have gone optional. The primary motto of introducing the Java EE was to reduce the complexities associated with the application development time. The Java EE since the version is consistently upgrading and finding ways to improve API and programming models for the latest applications and incorporate the features requested by the worldwide developers' community. The following are the few significant reasons for which we need Java EE in real-time. The advanced Java specifications in Java EE are incorporated to make a few requirements meet.

Generics are a powerful feature of the Java programming language. Numbers and Strings This lesson describes how to use Number and String objects The lesson also shows you how to format data for output. You will learn that all classes are derived from the Object class, and how to modify the methods that a subclass inherits from superclasses.
