  • Python: Python programs are generally expected to run slower, making Java a more preferable choice by enterprises than Python.
  • C++: There is an automatic garbage collection facility in Java, but this facility is not given in C++. Most objects are destroyed manually by the code.
  • Ruby: Ruby and Java programming languages have a lot in common. Both programming languages complement each other and can be used together when required.
  • C #: If you are developing an application for a Windows phone, you should choose C#. If you are creating an application for the android phone, you should choose Java in that case.
  • PHP: If programmers don’t have any time constraint, then they should opt for PHP. If the project emphasizes features like scalability, security, or performance, then you should choose Java.

2. The Applications of Java

Even though Java is no longer the only officially supported language for Android development and is far from the only choice for web programming, it keeps up with the competition. Java is the #1 language for DevOps, AI, VR, Big Data, Continuous Integration, Analytics, Mobile, Chatbots, and Social.

2.1. Mobile Applications

Java Developer Hourly Rate | Savvycom -5

For the creation of mobile apps, Java is the official programming language. It works with Android Studio and Kotlin, among other programs. You’re probably curious why just Java. The explanation for this is that it can run on the Java Virtual Machine (JVM), while Android executes class files using the Dalvik Virtual Machine (DVK). These files are then packaged together as an Android device package (APK). With Java and its OOPs rules, Android has a higher level of security and simplicity.

2.2. Web-based Applications

Web applications are also written in Java. It offers extensive support for web applications via Servlets, Struts, and JSPs. You can build any kind of web application you like with the aid of these technologies. This programming language’s simple coding and high security enable developing a wide range of health, social security, education, and insurance applications.

2.3. Enterprise Applications

Many software developers choose Java for writing applications, and Java Enterprise Edition (Java EE) is a widely used framework that includes an API and a runtime environment for scripting. Network software and web services are also included. JavaEE is also the backbone for many banking applications that use Java from the user interface to the back server end.

They have a higher degree of portability and need less upkeep. Java is used in some of the most powerful programs, such as MATLAB, for both the interacting user interface and the core system.

2.5. Gaming Applications

Java Developer Hourly Rate | Savvycom -7

The open-source most popular 3D-Engine, the jMonkeyEngine, supports Java and has unrivaled capability for developing 3D games. However, garbage collection cycles can cause noticeable delays in games, which can cause latency issues. This problem will be resolved in future JVM versions.

2.6. Big Data technologies

Java is responsible for the existence of leading Big Data innovations such as Hadoop, as well as the most powerful programming languages such as Scala. When designing Big Data applications in Java, it is clear that Java is the foundation.

2.7. Business Applications

The Java EE platform is intended to assist developers in developing large-scale, multi-tiered, scalable, dependable, and stable network applications. These technologies are created to address the issues that large businesses face. Enterprise applications are often complex due to the features that make them efficient, such as security and reliability.

By providing a development model, API, and runtime environment that enable developers to focus on functionality, the Java EE platform reduces the complexity of enterprise application development.

2.8. Cloud-Based Application

Cloud computing refers to the distribution of IT services over the internet on a pay-per-use basis. It offers a low-cost approach for IT infrastructure. Java has features that can assist you in developing applications to be used in SaaS, IaaS, and PaaS production. Whatever the need, it may help businesses develop applications remotely or assist businesses in sharing data with others.

Java Developers: Overlooking These Facts Can Cost You Money in the Cloud

Cloud computing services have been becoming increasingly popular in the modern age of technology. Providing a variety of services, from Infrastructure to Software, a large number of enterprises nowadays rely on cloud-based computing, either completely or partially. Whatever the case, its thriving existence is due to the fact that the total cost of ownership for Infrastructure as well as Software is complete – or at least proportionally – cut down.

Nonetheless, without careful management and planning, cloud services’ perks can easily poke a big hole on the firms’ budget. As such, before riding on the native cloud bandwagon, below are some facts that can help Java developers prevent the cost from getting out of control:

java developers facts for cut-down cost money in cloud

Choosing the appropriate VM model can make all the differences

Just like choosing hardware for your own server, selecting a suitable VM for Java cloud computing services according to your need is an arduous yet decisive task. On one hand, using a small VM can lead to various performance issues, or even trigger downtime during load spikes, causing the tremendous delay in the operational procedures as well as possible data loss and errors. On the other hand, using too big of a VM inevitably causes waste of resources during normal and idle periods. While this may seem like an acceptable cost when having your own servers set up, in serverless Java development, the issue grows proportionally due to the small inefficiencies keep piling up and replicate in each and every instance.

Another point to be taken into consideration is choosing a pricing model for VM usage. A common misconception is that cloud computing is compared to electricity consumption more often than not. However, the costly electricity bill is just a small fraction of serverless Java development costs. Generally, vendors provide their VMs in “pay as you go” billing model. This is where the mistakes are often made, where Java developers start with a small-sized VMs, and then gradually add more resources to it as the project grows. However, using a rented VM, adding just a few more resources to the VM means doubling your VM size, thus increasing the costs twofold along with it. Exacerbating the point, with a lack of elasticity compared to a physical server, performing unexpected downtime when there are issues or for adding more resources requires the current VM to be stopped, redeployed then migrated. This operation alone brings about several unexpected risks.

Consequently, knowing what you need and selecting the right vendor and price model for VMs is the first and foremost step to cut down the cost for Java Cloud Development.

Java programs’ optimization is crucial when making use of cloud computing services

java program

In nowadays’ cloud-native world, how Java developers utilize the frameworks is a direct factor determining the cost of the project. According to Graeme Rocher – the creator of Java application frameworks – on Forbes, most Java developers are only exposed to the surface level of the framework, tools, APIs, documentation and how to use it. That is why it is often the case when the application is deployed, they realize that it requires much more memory to run than expected, potentially raising the cost requirement. Unlike the traditional Java development method, deployment of Java on cloud computing services uses Cloud Operating Systems instead of Java Virtual Machine (JVM). As a result, it is imperative that Java developers involving in writing cloud apps think differently. For instance, cloud apps need to be responsive to restarts and failover, therefore need to be optimized to consume less memory while taking less time to start at the same time. Although at first glance, making apps more efficient and enhancing the program for low-memory footprint is the ultimate goal in the Java ecosystem in general, the technique for app implementation greatly varies. For runtime processes handled by JVMs, conventional apps benefit from the just-in-time compilation, which is highly beneficial for long-running processes. However, serverless Java apps are usually short-running processes, which is a recent trend in Cloud computing. This in turn completely negates all the advantages from the just-in-time compilation, as the process is only executed briefly then terminates immediately. Obviously, it is not suitable for serverless apps, which instead make use of cloud operating systems. The situation leaves Java developers in a dire need of a faster, more flexible system supporting fast cold starts, light-weight and short-lived processes.

Aside from the fact that Cloud-based Java apps need to transition away from the legacy architectures relying on JVM, contrary to most people’s belief, the Java application itself can be lightweight. The reason is that heavy-weighted Java apps are mostly because of its APIs and Tools associated with the program, which was provided to build frameworks by JVM. Thus, eliminating the use of JVM also mean cutting down on memory consumption of APIs and tools, making the program much more optimized for serverless deployment. All these hurdles can be alleviated by adapting Microservices into Java Cloud development.

Java App Development is Essential in the Age of the IoT

You might be surprised to learn that Java, the long-lasting and ever useful internet programming language, is even still around. Well, as it turns out, Java app development is at an all-time high. Hiring a Java app developer to write a program for your needs is easier than it was in the past due to high adoption rates across device platforms. Java web development has decades of refinement and knowledge behind it. Custom Java development is similarly popular, as Java is used in smartphones, wearable tech, and many other IoT devices. At Savvycom, our goal is to exceed standards in all facets of web development, and Java is one of the many options we give our customers. If you need a Java development company, look no further.

Why Java

java app development, java programming language, savvycom,

Why Java?

When Sun Microsystems released Java in 1995, they surely didn’t expect the impact it would have on the web to come. During the dot com boom, Java became the go-to programming language for any developer who wanted an easy to work with the framework. Browser compatibility gradually became universal as Java’s business-oriented code became more refined. Just like all successful programming languages, Java adapted to the changing hardware and technical climate. Due to Java’s ability to run on almost any hardware regardless of architecture, Java has become one of the most widely used client-web programming languages ever.

Savvycom is dedicated to bringing our customers to end products that not only satisfy the stated need, but do it simply, effortlessly, and in the time allotted or faster. We use Java in many of our applications (Jio Health, Realm,…) as a matter of confidence in the stability of the platform. The now decades of documentation that exists allows our Java developers to quickly find solutions to any issues that may arise. This is in addition to the years of experience our team already has in the field of Java app development.

Time is of the Essence

If you were to try to create your own CMS or backend media platform, how would you do it? Hire a team of developers to write your own code and start an entirely new language just for your business? This is not practical unless you like to throw money out the window. It is much more efficient to use an open source platform that already exists and that hardware manufacturers already build their products to be supported by. While there are a few other choices for serving media content, Java again has the most support and capabilities.

When you consider hiring a Java app developer, there are several things to think about. If you hire an individual, costs can be lower, but what happens if they aren’t capable of fulfilling your requirements? You will have to fire them and hire another, taking the loss. You could hire an in-house team of developers, but the overhead would be so great, any extra money available to enhance the project further may be spent on the time to develop it. By trusting in a Java software development company such as Savvycom, these concerns are eliminated. We have proven through our portfolio of previous projects that we have the experience and the team to finish any Java app development project that you might dream up. Our dedication to the Agile development model ensures that you will get what you ask for when you ask for it.

Computers Shouldn’t Suffer Memory Loss

Some companies and executives might remember a time when Java was known to be slower than other languages due to it having to be compiled to run on the hardware that the JRE (Java Runtime Environment) was installed on. Luckily, there are two factors which mitigate this. Many new hardware devices can decode and run Java directly, forgoing the need for a compatibility layer. Additionally, Java applications can now be compiled on the fly as they run, further speeding the application’s overall speed. Java comes with an automatic memory cleaner of sorts. When the code sees that there are no more references to a particular object, the memory that object occupies will be recovered and available for use. This will allow small devices with very low memory to run Java without becoming sluggish. Memory leaks are minimized as long as the Java app developer writes clean code. This is also another good example of why you want an experienced Java app developer on your side. Writing clean code that is optimized for your application and hardware is essential.

Get into the Swing of Things

Java, Swing java, java swing app, swing java app example, savvycom

Swing Java App

With Swing, Java allows applications to have the look and feel of other large well known operating systems and their GUI within your own application. This allows you to have the functionality of a native app, but without having to run outside of the Java environment. Applications using this type of architecture would be of advantage to any company that wants to run their own style GUI yet retain the basic functionality of a device within the app itself. There would be no need to leave the program to change the settings of a device. Additionally, Swing allows the entire GUI to be hot swapped, which could be advantageous for any hardware that runs solely on Java.

This kind of adaptability is why Savvycom employs our team of experienced and ‘savvy’ Java app developers. We take pride in being able to adapt to change, even if it’s smack dab in the middle of a project. In fact, we thrive on the enthusiasm of our team in such situations. With our internal structure optimized to maximize communication with the customer and respond to immediate needs, we are the Java app developers you have been searching for.

Have Your Cup of Java

In conclusion, we believe Java app development has a long future ahead. It pays to not only listen to the customer but to observe the market as well. So long as Java apps continue to be popular and hardware continues to support it, we will be the best choice to help you with your programming needs. Applications developed in Java by our team can be trusted to have a low incidence of hang-ups or failures such that you might experience with other developers. If you have an idea where Java can be implemented and are in a crunch for time, Savvycom is your answer. Just as well, if you have an idea and you aren’t sure about what platform you desire, we can recommend and implement solutions based on your needs in record time.
