Applet in Java and what should programmers learn about it

What is Java Applet? Well, Java Applet is nothing but small applications written in Java for developing attractive web applications. It is often written within the web page and thrown into the browser of the client or user. Once it is projected to the browser, it runs on the client hardware through the JVM i.e. Java Virtual Machine. It runs separately on the JVM hence it never hampers the resources of the browser. Sometimes it appears in a new window in the web page or in the appletviewer or even in a standalone frame. Anyway, it is always provides boost to the application. Though it is often written in Java but it also can be written in any other language that has the potential to compile Java bite code like Python, Pascal, JRuby etc. Java applets can run at a lightning speed like C++ hence it is extremely helpful for client side communications.

Java for Smart Business Solution - A Language to Survive Long

Java is extensively used in a wide range of platforms, starting from various embedded devices and mobile devices to different enterprise servers as well as supercomputers. Such has been the impact of Java on the fraternity of development that when it comes to providing smart as well a long term business solution, the language has become almost an obvious choice. This is mainly because of the features that the language comes up with. Experts are of the belief that much due to these unique features, Java will survive for long. Let us look into some of the features that have made the language an indisputably dominant force in the world of development.

Why Do Employers Search For Java Developers More Than Anything Else?

There is no doubt that Java today is one of the most popular as well as sought after software systems. Such has been the popularity of Java developers who have mastered Java skills that companies nowadays can go to any extent to hire a certified Java developer. Java has gone paces ahead of other languages in terms of demand.

The rise in this popularity can be attributed to the value added features that have made Java so popular.

Will Java 8 Adoption Rate Increase Amongst Developers?

Its design and programming features make Java one of the most popular computer programming languages. Despite being easy to learn and use, Java is platform independent, object oriented, multithreaded, robust and secure. Java also comes with networking capabilities to facilitate distributed computing. The developers can further write applications in Java SE 8 to avail a set of new features at the language as well as JVM level. Since its release in March 2014, the adoption rate of Java 8 is growing gradually among developers across the world. An increasing number of developers are switching to the most recent version of Java to avail several innovative features.

Hibernate in Java and Its Features

As an open source persistence library, Hibernate Object Relational Mapping (ORM) is used widely by Java developers. The framework provided by Hibernate makes it easier for Java developers to map an object-oriented domain model to a traditional relational database. Thus, Hibernate in Java uses direct persistence-related database access to resolve problems related to object-relational impedance mismatch. It comes with high-level object handling functions to facilitate object-relational mapping.

Struts - In What Ways Does It Support Java Programming

Apache Software Foundation (ASF) has developers Struts as an open source web application development. The framework is being used widely by programmers to create Java EE internet applications. It enables web developers to create application by using model-view-controller (MVC) architecture by adopting and extending the Java Servlet API. The Java programmers also have option to use WebWork, a framework spun from Struts. Despite retaining the original architecture of Struts, WebWork comes with several enhancements and refinements. Thus, the Java programmers can rely on Struts to create large and complex enterprise application by keeping the model separate from view and controller.

Java Strings - Few things that Java Programmer Should Know

A Java class that is very widely used is known as string. It is considered quite special since compared to a normal class it contains some unique, special characteristics. It consists of some characters in a sequence; through the class the object can be created. There are many concepts which can be carried on through this and are worth knowing by most Java programmers.

Creation of objects or instantiation- The object can be created in two different ways- through new keywords and through string literal. Through double quote a string literal can be created. With its creation each time, the constant pool is checked by JVM first. If the pool already has the string then it returns the pooled instance’s reference. If the pool does not contain it then a new object is instantiated which is then placed there. Memory efficiency is increased by this. Through keywords, the object is created in a straight-forward manner by JVM.

Java for E-Commerce business - Is it good?

The computing platform, Java is independent, secure as well as robust, ensuring high performance. This network savvy, portable as well as architecturally neutral language uses automatic memory management. The programming language can be used to develop ecommerce applications easily due to the several feature sets that make it an effective ecommerce platform. It is platform-independent, network-aware, multi-threaded as well as object-oriented which make it really flexible. Near about any platform can be used for its running. Some of the reasons that have made it suitable for ecommerce business are discussed here.

Java 2 Enterprise Edition- Also known as J2EE, it has proved to be a revolutionary influence in the arena of e-commerce. Strong server side application can be build through the robust and solid solution of J2EE. The technology is fully-able and is extremely beneficial as a development tool. Some of the tools included in it that helps in this respect are Servlets, JSPs or Java Server Pages, Enterprise JavaBeans or EJB, JNDI or Java Naming and Directory Interface, JDBC or Java Database Connectivity, JTA, JMS along with Java Mail.

No programmatic configuration of navigation- To set navigation, a specified pattern has to be implemented which can be really complicated as well as a time-consuming process. But when you are using JSF, all the complicated procedures can be avoided altogether. The framework handles the navigation entirely. All that is needed is to associate page views, URL patterns as well as logical outcomes together by using Faces configuration file. Developers can also follow another method- using the implicit navigation feature of JSF 2.0 that forwards requests automatically to a view having the same name as that of the requested URL pattern.

Good templating support- The Facelets technology can be used for templating and it helps maximize markup reuse so that redundancy in page views can be reduced. It also allows the preparation of views through standard XHTML syntax. It allows easy creation of template layout which is common for all page views. In fact the views can be rendered with the insertion of content that is view-specific in the template.

Neutral platform- Several kinds of communications are required in ecommerce and there is a lot of data that changes hands. For the interaction of so many various kinds of systems and platform, you need a neutral standard platform that helps in this data exchange. This requirement can be filled up with XML or eXtensible Markup Language. It is quite crucial; the role of Java here is that it provides a great support to XML which combines well with this programming language.

Validation support is in-built- Server side validation support is provided by JSF. All validation can be performed by creation of validator class as well as logic that is manually coded. The server-side validation will occur automatically by virtue of JSF at the particular phase.

View rendered with several markup languages- The API technology boasts of flexible rendering that enables the attaching of several renderers to component tree of an application that is JSF-enabled. Thus custom components can be created.

Server support- Java is supported by several application servers like IBM WebSphere, BEA WebLogic, etc which are full of different types of features. Now, any one of them can be easily chosen due to the support extended.

Labour division well-defined- A huge advantage of this technology is that there is a clean separation between presentation and behaviour of web apps. This is especially great for large projects since it provides separate development areas where various team members can focus differently.

Ecommerce developers prefer Java over any other platform since it offers a number of benefits in areas such as security, ease of use, portability, flexibility and accessibility. It is present at both server as well as client sides and coupled with its efficacy this makes for an unmatched killer combination.

Why is Java considered as the most secure language?

The development language called Java is used mainly for the creation of software which may be used regularly. Most people have downloaded some program or the other that requires Java runtime. The design of the platform puts strong emphasis on the security factor. The core of the language is type-safe, providing automatic garbage collection to enhance the application code’s robustness. A verification mechanism and secure class loading ensures the execution of legitimate Java codes only. Initially the platform version resulted in the creation of safe environment to run codes that are potentially untrusted like Java applets that have been downloaded from public networks. With the widening as well as growth of the range of deployment, there has been corresponding evolvement of its security architecture so that a bigger range of services can be supported. The architecture constitutes of a large number of tools, APIs as well as algorithms, protocols and mechanisms that may be implemented.

The platform has a set of APIs that span major security areas counting public key infrastructure, cryptography, secure communication, access control as well as authentication.

Public Key Infrastructure- PKI for short, this refers to a framework which enables secure information exchange through public key cryptography. Identities are bound to digital certificates, providing a means to verify authenticity of certificates. Certificates, keys, trusted Certification Authorities which generate as well digitally sign certificates and public key encryptions are encompassed by PKI. It has two tools in-built called keytool which is used for the creation as well as management of key stores and jarsigner which is used for signing or verifying signatures of JAR files.

Cryptography- This framework helps to access as well as develop cryptographic functionality. There are some APIs which render many kinds of cryptographic services that include symmetric bulk encryption, message digest algorithm, symmetric stream encryption, digital signature algorithm, elliptic curve cryptology, password based encryption, key generators, key agreement algorithms and message authentication codes.

Secure communication- Data travelling across network is susceptible to security risks since anybody can access it; it is especially a risky business if the data is concerned with private information like credit card numbers or passwords. So the data must be made unintelligible so that unauthorized parties cannot understand it. You should also ensure that the data is being sent to the appropriate party without any intentional or unintentional modification during transport. For the best secure communication, cryptography acts as a base through SSL/TLS, SASL, Kerberos and GSS-API.

Access control- This ensures that the Java platform is protected from access to sensitive application code or sensitive resources. A security manager mediates all decisions for access control. APIs that help in this process are permissions, access control enforcement and policy.

Authentication- The process helps in the determination of a user’s identity when a Java program is being executed. Sometimes login module plug-ins while in some cases cryptography related services, are needed for authentication.

Bytecode- After successful java program compilation, a class file is generated by java compiler with .class extension containing the program’s Bytecodes. The generated Bytecodes are secure which may be run on any JVM containing machine. There is a verifier which is invoked so as to ensure the execution of just legitimate bytecodes in Java runtime. It ensures that bytecodes and Java language conform to each other so that namespace restrictions or rules are not violated. Verifier also looks for stack overflows or underflows, memory management violations as well as illegal data typecasts. After verification, the execution may be conducted.

Java is often considered as the most secure language amongst all other languages. However, still some people feel that it is not secure since the plug-ins pose some problems. In fact, they certainly do that, but the inherent nature of the language is very secure. The security infrastructure is very strong with so many APIs and tools which contribute towards making it more secure than many other languages.

The story of JavaScript's Success

As a hugely popular coding language, JavaScript is commonly used along with HTML to develop all types of websites. Many experts even include JavaScript in the list of top ten widely used programming languages. Despite having similarity in syntax to Java, the interpreted computer programming language allows developers to develop cross platform web application. However, the popularity of JavaScript was affected temporarily due to launch of specialized web application development platforms by large companies like Microsoft.

As each user has options to choose from a range of operating systems, web browsers, and devices; most developers, nowadays, use JavaScript as a powerful cross platform programming language. Also, each developer has option to choose from a number of cross platform versions of JavaScript, to target all major platforms including Mac, Windows and Linux. The similarity of its syntax to C, C++, C#, and Java further makes it easier for the code writers to write programs without putting much time and effort.

What Makes JavaScript Popular as a Cross Platform Programming Language

Making Websites Interactive

The frequently changing web browsing habits of users have made it essential for businesses to develop engaging and interactive website. As a flexible language, JavaScript enables you to make your website more interactive in adding drop-down menus and specialized text effects. At the same time, the powerful scripting language can also be used to develop interactive games, and full JavaScript chat rooms. Some of these features can also be used to improve the user experience by optimizing the navigation options that will encourage users to access the web application regularly.

Compatibility with Major Web Browsers and Operating Systems

No developer can decide the way a user will access the web application. But each developer has to ensure that the application can be accessed with major operating systems and web browsers. As major web browsers like Internet Explorer, Mozilla Firefox, and Google Chrome have built-in support for JavaScript; the end users can access the website without downloading any additional software or plug-ins. However, the script will change the look of your website based on the web browser used by the end-user. Regardless of their choice of websites, the users can enjoy the interactivity of the website. Also, a user also has option to turn the JavaScript code on and off to suit his requirements.

Reducing the Web Server Load Often webmasters and website developers look for options to reduce the web server load. Some web application development platforms like Microsoft Dot Net allows you to develop server-side controls. But developers still use JavaScript a dynamic client-side scripting language, The features further contribute towards loading and executing web pages directly on the web browser, without waiting for response for the server. The web browser will automatically download and launch JavaScript, and display the web pages to the user within a few seconds.

Special Compilers Not Required

Unlike some other programming languages, JavaScript does not require any special compiler or editor to run. So a developer can easily learn the coding language without putting any additional time and effort. You can simply use Notepad, WordPad or any other text editor, and write the JavaScript code to achieve certain objectives. At the same time, the JavaScript code can also be inserted directly into HTML pages of a website. Further, the code can be uploaded to the web without using any specialized software or script.

Already Integrated with Popular Web Technologies

The huge popularity of JavaScript has encouraged many companies to incorporate the scripting language with other technologies. For instance, the animation technology Flash integrates JavaScript into its XML-based technology. Similarly, JavaScript is also supported in PDF files by popular Adobe products like Acrobat and Adobe Reader. Further, JavaScript can easily interact with control java applets used in designing a web page. So a developer can use these advanced technologies to design interactive website as well as powerful internet applications including java game development projects.

Before few years, many developers were using JavaScript to control the look and presentation of web pages. Normally, the scripting language was used for randomization of content, validating web forms, controlling cookies, and adding visual tricks to a web page. But the developers, now, use JavaScript as a full-featured and powerful language to develop web application compatible with major web browsers, operating systems and devices.
