Java Generics – A Basic Introduction
Java Generics is facilities of additional generic programming, which were introduced into the Java language in 2004, along with version J2SE5. They are designed to support “a powerful type or instance to operate directly on objects of different kinds while providing significantly improved type safety at the same time”. More on the topic, “type safety” is a phrase used to represent the notion that a program’s code will be well typed at run time without requiring any extra overhead at runtime. In other words, type safety means that a program’s value or references will not change during its execution.
Java Generics can be regarded as defining the syntax of Java code generators. It enables one to create and use generic classes and objects. This facility allows code writers to more conveniently extract the most meaningful portions of source code from existing Java source code. It also allows source code to become more flexible and generic in nature. Java generics thus allow programmers to more conveniently define and reuse generic objects and classes.
The main benefit of Java generics is that they enable programmers to more conveniently specialize Java code. For example, when writing XML, programmers need to be concerned about which character characters would be interpreted as text characters or as numerals. However, when writing Java code, programmers needn’t worry about such details. Since the generic nature of Java code allows it to be specialized, all these concerns can be easily taken care of. Moreover, the resulting classes and objects would satisfy the requirements of the target language.
Java Generics makes it easier to implement generic code. Java code generators are able to generate a wide variety of code types that can be used in the different Java applications. This way, programmers are spared from writing too much boilerplate code for each and every kind of object.
Another advantage of Java generics is that they enable the programmer to create reusable generic objects. The programmer can easily create generic versions of collections, including list, Map, Set, Tree, or Bag. He can also create generic versions of methods on any type of object. For example, a Java programmer can convert a List of int s into an ArrayList of int s without much effort. Such examples clearly demonstrate the power of generics.
Java code generators are also responsible for generating source code for the various interfaces. For example, a Java programmer can easily create interfaces that satisfy the requirements of the XML specification. Similarly, a Java programmer can reuse the generic methods of other objects in order to obtain the desired results. In fact, whenever an existing generic object is re-used to provide a functionality, the implementation of that generic class is changed. This means that the generic code generator has to re-generate the code for every use of that generic object.
However, Java code generators face certain disadvantages as well. Firstly, they generate a large number of boilerplate code that many programmers find difficult to follow. Secondly, they are limited in the amount of code they can use to implement their project. Thirdly, they often generate code that does not make sense in the specific situation. Finally, Java code generators often fail to adequately express the logic behind the generic type. In some cases, this can lead to unexpected behaviors when the code is executed.
On the other hand, the Java platform’s generic programming tools provide a flexible vocabulary and powerful tools for managing generic objects. Java applets are one such example. These toolkit applications allow the programmer to create applications that run on the Java platform by wrapping standard Java code in a convenient application framework. Java applets are written in high-quality proprietary libraries, allowing them to be integrated seamlessly with the rest of the Java language.
Java Auto Boxing – A Powerful scripting Language
Java Auto boxing is one of the first things that come to mind when one thinks about Java. Java is a highly popular programming language that can be used for writing code that will run on the desktop, laptop and web-browser. But what is Auto boxing? It is a tool that helps in formatting the HTML code so that it appears more uniform. This helps it to read just as well from various systems including HTML, XML and SOAP.

This is where Java Auto boxing steps in. It is a type of formatting tool that helps in transforming the HTML code into a more readable form. One such example is the XHTML code. Once the code is transformed, it becomes easier for a reader to understand and decode the meaning. Java has made things easy for all by introducing a number of tools that make formatting jobs simple and easy.
In order to begin with it is necessary to download and install the correct Java Runtime Environment. Without the correct JRE it is impossible to run any program under the Java Virtual Machine. Once this is installed a default configuration for the Java virtual machine is used. This is an excellent convenience as there is no need to select a specific one.
There are a few ways in which the Java virtual machine is embedded into the applications. Primarily, it is utilized during the compilation process. The generated code then links with the programs that depend on the external Java libraries. Since most of the popular libraries are written in Java, it can be easy to locate and install them. One just needs to search for the library and install it.
Java Auto boxing provides facilities to create, manipulate and customize the Swing components. It also extends support to the various control surfaces such as the Text object, the View object, the listeners and many others. It is a high speed web application framework that can be used for developing robust web applications. Moreover it has a rich set of tools that allows its users to construct, create, manipulate and maintain GUI applications with ease.
This powerful scripting language can be used both to create lightweight web applications and to build sophisticated web applications. To build simple web pages, it can be used as a simple scripting language while writing more complex web pages with ease can be done through the use of Java’s own compiled database features. In addition it also supports the use of a Java Beans Environment that makes it easy to create customized components. These components can be used in a Java application to create reusable objects. Furthermore it supports the concept of pattern matching and generic programming that make it a safe and convenient programming language for all.
As it can be used as a programming language it comes with a large collection of tools and libraries. It comes with the Apache server and a number of other libraries that provide support for different types of servers and web servers. Apart from being a safe and simple scripting language, it is fast. Moreover, one will never get bored as it keeps its users entertained. It is free from any type of bugs that can hamper one’s productivity while using it.
