Java is one of the fundamental programming languages that have been used in many product developments. The simple reason for this is because Java can be put to use in various platforms due to its multi-platform nature. In fact, because of this, Java is the most used and a must learn programming language for any computer programmer.
Product vs. Application Development
While people often hear about application development, it is not to be confused with product development. This is because application development is often focused to a particular business with its own set of requirements whereas product development has a generic set of objectives. To make it easier to understand, application is to solve a particular problem that is present whereas product is used at a broader sense instead.
When we talk about product development, what we are talking about actually is something that doesn’t have all the detailed features needed. However, it can expand itself through the use of plugins or a third-party application to conform to the user’s or business’ need. This also means that a product can be very versatile as it can be used with various scenarios. Think of the Windows operating system as the product and Google Chrome as the application. Windows is easily the product because it can have various things added to it (and thus, various scenarios) but Google Chrome on the other hand, has one main purpose and that is web browsing. Products and applications complement each other but each serves its own purposes.
We are quite sure that you have heard of Java and its miracles but there are also many other programming languages as well. Such example includes Python, Ruby, and C++ to name a few. However, Java is still one of the favorite choices for developers for many reasons. As of date, Java is one of the most secure programming languages that anyone can learn. It is of no surprise that many banking solutions make use of a lot of the Java programming languages due to its secure nature. In fact, Java makes use of its own ‘sandbox’, which means that nothing (read:malware) can control the application from outside of the sandbox.
In addition to that, many enterprise solutions also make use of Java due to the possible types of integrations associated with it. For example, through Java, it is possible to integrate the application or product with various web services such as payment gateways, crud applications as well as health domain applications. Suffice to say that the possibility through Java can easily be endless but it doesn’t mean that everything should be developed with Java.
Java has been the solution to various platforms that are both developing and stable. In fact, there are many noteworthy companies and projects that use Java for their day-to-day jobs. Some of the ones that you might have heard include Google Maps, Blu-ray discs, Kindle and a few other devices. In addition to that, laptops, supercomputers, and cell phones are also supported by Java making it a very versatile language as compared with others.
In statistical terms, there are roughly 1.1 billion desktops that run Java, 3 billion smartphones running Java, 1.4 billion Java Cards manufactured and is also being used in GPS systems, parking payment stations, lottery terminals, ATMs and many more. That is the power of Java not found in any other platform in the market.
Following are some Java development technologies, tools, and frameworks used to design complex architectures and built applications:
- Struts, Spring, Hibernate and JPA
- JAXB and Apache Axis 2/Java
- JSP, Servlets, JDBC, EJB, JMS, JTA and JUnit
- Apache Tomcat, JBoss and GlassFish
- Eclipse, Netbeans and JBoss tools
- jBPM and Drools
Products to be developed with Java
Software written on Java runs on every kind of operating system and platform in existence.
But developing products and applications using Java is associated with a number of challenges, like:
- How to engineer the application so that it is lean, secure and productive and does not become a performance nightmare that Java is usually associated with?
- Which of the many Java frameworks and technologies should be used during project deployment?
- Does the business case justify usage of Java, or should you explore something else?
Applications made for the sake of presentation might not be best to be created with Java. The reason is simply because there are already numerous applications that can do a presentation application quickly and easily. It would be better to spend the money for the content instead of Java application development because that is the main focus of a presentation application.
However, Java is the solution if you need a product that deals with a lot of business logic implementations. Such examples include transactions, record keeping and many others. This is simply because Java works best in an environment where you need calculations or logic implementations instead of good visual presentations. In addition to that, in an environment where security is paramount, Java is one of the only programming solutions that can cater to this.
Why do Programmers choose Java
Throughout the earlier paragraphs, we have mentioned, on the surface, the advantages associated with Java. You can be rest assured that the advantages of it far outweigh the disadvantages and this is one of the main reasons why Java has been such a favorite amongst many programmers. In fact, a lot of websites today won’t work unless you have Java installed on your system. More of these websites are created by the day and simply because Java is fast, secure and reliable. So let’s take a more detailed look at why programmers chose Java:
We have mentioned a lot about security regarding Java. There are many versions of Java but a lot of them make use of the same concept. Java ME (J2ME) for example, is a mobile platform that works for most mobile devices. This solution is considered very safe for mobile platforms because it runs the application on a separate environment. This is also called “sandboxing”. By sandboxing the application, it means that the program will not be able to access the files of another application. In addition to that, it also restricts the application from using the hardware in an uncontrolled manner. This reason alone makes Java a favorite amongst banking companies, as exploits on the application will not affect the system as a whole.
Codes in Java can easily be reused between one application and another. This means that you will not need to write the same function twice and that can cut a lot of time where programming is concerned.
Another reason why Java is a favorite amongst many is because of its cross-platform nature. This means that by programming an application in Java, you can run it on Windows, Mac and even Linux without needing to alter the codes in the application. In addition to that, Java is also used in a lot of computing platforms ranging from mobile phones to enterprise servers and supercomputers. While you don’t often see Java applications on a computer, its use on the enterprise level is unmatched with any other programming languages.
Another beauty in Java that is not found in any other programming languages is distributed computing. This means that a task made by a Java application (or applet) can be distributed throughout the computers present in the network. This means that you can run three different applications on three different systems but still have them working together to form one complex application. In other words, different tasks can be given to different computers so that one system will not be in charge of doing everything.
A lot of today’s programming languages have multi-thread capability built into it but the methods often differ from one operating system to another. In other words, different platforms need different codes for it to work the same. In Java, multi-thread capability is available regardless of the platform that is being used. This is because the runtime environment interprets everything and the people in Java have done those parts already. The programmers only need to think of their codes while the compilation and runtime is done by Java environment itself.
For a lot of developers, they often take a look at a platform’s frameworks so that they can get their work up and running as quickly as possible. As far as Java frameworks are concerned, there are many of those that are available. There is the Strut and Spring Framework that provides a lot of services such as remote access framework, remote management, model-view-controller, data access and many more. Spring Framework also makes use of aspect-oriented programming framework that can be a bit less powerful but also less complicated for the programmer.
Database Driven Programs
Through Java, you can create applications based on a set of databases. This can be used to create applications needed for most business jobs. In fact, this can help you to create various applications such as polls, forms processing, forums, stores and many more.
Disadvantages of Java
Slower than Native Language
While Java is a cross-platform solution, it is noticeably slower as compared with applications that are created with its native operating system language. This is because Java runs on a virtual machine (part of its sandboxing feature) and can be slow, depending on the platform. While Java has been annoyingly slow in the past, it isn’t so today simply because of the performance found on today’s computers. In addition to that, Java also takes more memory as compared with native applications and that can be a problem on legacy devices.
Look & Feel
In the age where applications today look good and colorful, Java based applications still have the same look as it was before. While you can play around with the GUI, Swing is still a favorite of many users simply because it is easy to write and a lot of programmers have familiarized themselves with it. There are other alternatives to it that you might want to look.
Java is highly suitable for products that implements a lot of business logic. Its advantages far outweigh its disadvantages. The security and cross-platform nature of Java also makes it a winner.
