Why You Need Java

java development company and java development services

Java is a timeless and long-lasting technology. This mature yet constantly evolving  programming language serves to develop software for desktops computers, enterprise servers, mobile devices as well as web browsers.

How is Java applied in software development? You can build everything: from ordinary web-based applications to advanced back-end systems, data processing engines and games, and various highly-scalable software solutions.

Java is an object-oriented programming language which makes complex problems easier to solve providing greater modularity. Java objects allow for the code to be reused, which simplifies testing as well as troubleshooting. But these are only a few of Java advantages.

Java still remains one of the most widely used programming languages thanks to many unique features and benefits, some of which are listed below.

Security

Java is known as one of the most secure programming languages. Thanks to features such as: Java Virtual Machine (JVM), lack of pointers, secure APIs, bytecode execution, memory management, exception handling, cryptographic functions, you don’t have to worry about data leaks or injection attacks. With Java, your application will always be safe.

Scalability

As the business grows, so does the IT infrastructure. Java offers a multitude of tools that enable building enterprise-grade software with scalability in mind. It supports modularity, static type checking, advanced analytics and debugging tools, as well as libraries that provide asymptotically optimal algorithms and data structures.

Fast development process

Custom software development is a complex journey that consists of many iterations. The speed of the entire development process depends on general project requirements, technical challenges, code quality, resources, framework, and last but not least, the programming language. In order to accelerate software development, Java is the best choice due to its advanced features that enable it to develop software in a faster and more efficient way.

Memory management

Java has an automated memory management method, known as garbage collection. It can be executed on a JVM by automatically deleting objects that are no longer needed. What does it mean in practice? An increase of the speed and performance of your application.

High-Performance

A software designed in Java is able to process massive amounts of data, which makes it fast and reliable. This allows for an improved user experience, better lead conversion, thus providing a significant competitive advantage.

Popularity

Java programming language is one of the most popular among developers. It means there will never be a problem finding experts. On the other hand, due to Java’s powerful features, it is chosen by world-class companies, such as Google, Airbnb, Meta, Uber, Spotify, Netflix to develop their software.

Community support

There is easy access to a number of frameworks and open-source libraries for every case. Along with a large and supportive Java community, finding the answer to any issue is effortless.

Flexibility

This feature applies to many aspects of Java software development. It is characterized by its user-friendly and flexible interface for Java developers, which, as a result, speeds up every development phase. Also, due to Java’s platform independence, a code written in Java can be moved from one device to another.

As a distributed language, Java allows developers to simultaneously use several data center nodes to minimize latency of applications. All this makes it possible to use a wide range of solutions when building advanced software.

Vast usage in large-scale projects

Due to Java’s great capabilities and versatility, there are no limitations when it comes to custom software solutions of any size. Examples of using Java are: desktop GUI, web-based, or cloud-based applications, travel search engines, games, Big Data technology, IoT devices, advanced system integrations, e-commerce solutions.

Cost-effective

Development costs with Java are significantly lower compared to other technologies. The reason is related to the time spent developing the software. What is more, applications written in Java are easier and cheaper to maintain.

Efficiency

Java, as a compiled language, is known for its efficiency as it compiles all the code at once. This prevents delays of execution time. Consequently, the use of energy is lower, which makes Java an environmentally friendly option. Nowadays, choosing energy efficient languages that can significantly minimize energy consumption is crucial.

Below you can see a comparison of the efficiency of the languages: Java, C, and Python.

 

Elapsed Time (seconds)
Iteration C Java Python
1 196.83 85.81 2872.74
2 200.66 82.38 2681.26
3 199.15 83.02 2921.2
4 195.11 86.8 2945.17
5 198.68 85.05 2685.17
Average 196.083 84.612 2821.108

 

Based on these results, C is 2.34 times slower than Java and Python is 33.34 times slower than Java (source).

Low latency applications

Business applications are in high demand these days. As a result, software developers continuously strive to create low latency systems with reaction times measured in microseconds. For this reason, if you choose Java, the problem of latency disappears.

FAQ

What is Java?

Java is a widely popular general-purpose, object-oriented, class-based programming language with dynamic memory allocation and automated garbage collection. Java runs on Java Virtual Machine (JVM) that itself can run on many hardware architectures. Practically, Java is used to write stable applications of any kind and any size.

Why choose Java for my software development project?

Java often hits the sweet spot when starting a new software development project because of the proven JVM virtual machine, wide selection of mature frameworks and libraries, and a large global talent pool.

What kind of applications can you develop using Java?

Java and JVM are great for building web, mobile, and data processing systems. This is because of its interoperability, fast execution, static type checking, dynamic memory allocation, and modern extensions like Kotlin.

What are the main features of Java?

The key feature of Java is a proven track record of being a technology foundation for large, mission-critical systems. 

What makes Java a fantastic choice for building a long-lasting application is the following:

  • a possibility to build and develop your system locally and then run it on servers of any size and architecture;
  • the high-performance execution of JVM;
  • static type checking;
  • great selection of modern and mature frameworks.

What are the limitations of Java?

Java can be run on any hardware architecture supported by JVM, but it may not be that fast as assembler or C optimized for a specific machine code.

Is Java secure?

Java is a very secure language due to three main reasons:

  1. Java code runs in a Java virtual machine, which is an isolated sandbox.
  2. Java dynamically allocates and manages memory, which makes it impossible to introduce many types of security flaws related to memory management.
  3. The encryption and cryptographic functions available in the Java ecosystem are widely used and proven to be secure.

What is the best framework for Java web development?

Spring Boot Framework is the most popular Java web development framework due to its variety of mature, built-in features that shorten time-to-market of your products. 

How to design a high-performance Java system?

When designing high-performance Java programs, it is important to follow the slowest processing unit principle to remove bottlenecks. Also, make sure to avoid:

  • slow synchronous operations like I/O operations of network wait operations;
  • single-thread processing, when the computational task can be split into multiple and still chunky batches that could be executed in parallel;
  • misuse of CPU cache by using memory-inefficient Java structures.

Remember, your data fits in RAM. Check this article: Latency numbers every Java developer should know

How to build a low latency Java system?

A design of a low latency Java system needs to follow similar principles as a high-performance architecture. We also need to remember that the key is to minimize our response/processing time per request. Reactive programming would become a handy processing model here. In this way, we are able to decouple unit operations and execute them as asynchronously as possible to minimize the response time and maximize the resource usage. Spring WebFlux available in Spring Boot Framework or Akka are mature Java frameworks that will help you introduce reactive programming models to your applications.

Is Java suitable for machine learning and artificial intelligence applications?

Yes, although Python is probably the best choice for prototyping due to large availability of different AI/ML algorithm implementations you may try. However, the numerical computation code in Java is at least 20-30 times faster compared with a direct implementation in Python. This results in a 20 times cheaper and smaller system that needs to be run in your production environment.

Is Java still a good option for software development?

Yes, Java programming language is a fantastic option for software development due to its security, high-performance, mature set of proven frameworks and libraries, well-defined standards and a large global talent pool.

How can I keep track of my Java development process?

We strongly believe in extensive communication and transparency as the best options to mitigate project risks. This is why we apply an agile approach to all our projects (see our values: About Us). You may learn more about our development process here: How We Work. 

Can I expect support after the project ends?

Yes, we provide maintenance and extension support for Java applications of any kind. We have implemented many Java projects serving various industries, such as ecommerce, travel, fintech, and healthcare.
