Java can be the right tech choice for your product.
Java has become a more widely used programming language by companies around the globe over the last decades. It's a very flexible language that can be applied to the development of enterprise, mobile, and web applications.
This comprehensive guide explains why Java is still the most frequently used programming language across all fields and how to find the Top Java developers.
What is Java?
Java, a general-purpose object-oriented, class-based programming language, was created with fewer implementation dependencies in mind. Java is thus fast, safe, and dependable. This programming language aids in developing applications for smartphones, game consoles, laptop computers, data centers, and other.Java is
Object-Oriented
It means that a developer can organize software as a combination of several objects, such as classes, while coding in Java.
Simple
Java has a straightforward syntax that is based on C++. This programming language is also simple to learn and understand.
Platform Independent
The Java compiler creates a one-of-a-kind bytecode that is delivered to the Java virtual machine, which is stored in random-access memory. As a result, Java code can run on any operating system (Linux, Microsoft Windows, etc.).
Multi-Threaded
It is one of Java's most powerful features. It means that developers can write multi-threaded programs (2 or more) that can run at the same time. In Java, there are two main mechanisms for implementing a thread: extending a thread class and introducing the running interface.
Architecture-Neutral
Because a compiler generates bytecode that does not interact with a specific computer architecture, Java has a neutral architecture.
Robust
Java has a strong type checking mechanism that underlines time error and runtime checking processes. During a coding process, grammatical mistakes are highlighted, which reduces the number of errors in the final code.
- The Java programming language was originally known as OAK. It was originally designed to handle portable devices and set-top boxes.
- Sun Microsystems changed the name to "Java" in 1995 and modified the language to capitalize on the burgeoning www (World Wide Web) development business.
- Oracle Corporation later acquired Sun Microsystems in 2009, gaining control of three key Sun software assets: Java, MySQL, and Solaris.

Where is Java Used?
Now that we know Java is still one of the most widely used technologies, what will it be used for in 2024? Let's take a closer look at each of the major fields.Web-Based Programs
Java enables the creation of many apps for health, education, and insurance due to its simple coding and high security. It works with Servlets, Hibernate, Spring, Struts, Apache HTTP web-server, Apache Tomcat, Thymeleaf, and many other tools.
You can create any web-based application using these technologies. E-commerce web applications use this language as well, thanks to open-source eCommerce platforms like Broadleaf. This language is used in web-based applications such as Gmail, Google Sheets, Google Slides, and many others.
Android Application Development
The target platform of the application dictates the technology stack when creating mobile apps. For example, apps for the iOS platform are created using Objective-C and Swift, but only 17% of devices use the iOS platform; the remaining 83% use Android.
As a result, it is the most widely used programming language for creating Android applications. Kotlin, which is its main competitor for application development, is merely a "cleaner" version of Java because it is compiled to the byte code that the JVM executes. The most popular tool for creating Android apps, Android Studio, is compatible with Java.
Embedded Systems
Many products, devices, and intelligent processes, such as machine learning and artificial intelligence applications, are powered by embedded systems. Four categories of embedded systems can be distinguished: Real-time, Stand-alone and Networked Mobile.
In the modern era, it is nearly impossible to find a product without this technology. Microwaves and refrigerators are both examples of standalone embedded systems. And virtually all of these systems employ Java.
Big Data Technologies
Is Java still relevant for cutting-edge technologies? Big Data has been one of the most widely discussed topics in recent years. For Big Data, developers most commonly use Scala, Python, and Java.
Furthermore, Java is used in a variety of technologies, including Apache Hadoop, Apache Mahout, and Apache Storm. As a result, it is also an excellent choice for Big Data.
Cloud-based Applications
Java is also a good choice for utility computing. A cloud-based application is internet-based computing. So every time you check your email, use Google Drive, or conduct an internet search, you benefit from a few cloud capabilities.
This language facilitates application development in 3 cloud delivery models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Furthermore, many cloud building tools for Java, such as AWS SDK for Java, Oracle Cloud service, Google App Engine, and others, aid in the design and configuration of servers.
That is why many businesses hire remote Java developers to assist in the implementation of the cloud transition for business continuity, increased scalability, and cost-efficiency.
Gaming Applications
The mobile gaming industry is expanding year after year, and we anticipate that it will continue to expand. We've already mentioned that Android powers 83% of all mobile devices. And, because Java supports the Dalvik Virtual Machine, which runs on the Android platform, as well as jMonkeyEngine (a 3D engine capable of creating 3D games), it is the primary language for Android games.
Software Tools
Is Java used anymore in software solutions? A software tool is one of the most important things for a developer because it helps build, debug, and support programs. Developers commonly use Eclipse, NetBeans IDE, and IntelliJ IDEA tools, and all of them support Java. Even more, all of them were written in Java.

Why Do Companies Choose Java?
Let's move on to the Key Business Benefits of using Java section. What makes Java an excellent tech choice picked up by top notch companies among other programming technologies?High Performance
Java's high performance is one of the main benefits for your company. The precise run-time is uncoupled from the bytecode interpretation. The burden of extremely poor memory management performance is successfully lifted because memory management is handled by a single thread. Java is the best choice if you want to incorporate high-performance features into your application.
Write Here, Run Everywhere
Java's "write here, run anywhere" capability is one of the features that make it a popular language. The Java platform eliminates the need for developers to write code multiple times in order to create applications for various platforms. The code for an application is only written once, and developers are free to run it on any platform. All major platforms easily integrate it, and it is also included in consumer electronics like smartphones, PDAs, and televisions.
Powerful Frameworks
Java has extensive libraries packed with numerous potent frameworks, such as the spring framework, which has grown over time and provides Java engineers with a convenience. They can easily select a framework that best meets their needs. These frameworks have also sped up, improved, and reduced the cost of developing websites and mobile applications.
Language Independencies
You should be aware that the Java Virtual Machine, also known as JVM, only comprehends bytecodes. The application can be run on the JVM if the developers choose to convert the source code of any language to bytecode. Java's language independence feature enables developers to take advantage of the skills of various programmers on a single Java platform.
Reusable Components
Users won't encounter any difficulties using the pre-made components, and their operating system won't either. Additionally, any Java API can easily be located in accordance with the demands and requirements of a project.
Ease of Testing and Debugging
In Java, written codes are tested line by line, and errors are quickly found along with the specific line numbers that contain them. As a result, it is simple for developers to debug and identify errors when they arise.
Deep pool of software talents
There is no shortage of skilled and knowledgeable remote Java developers available for hire for your project. Because of the language's enormous popularity, finding a developer for your project won't be difficult.
Security
The best part of using the Java framework is that it offers cutting-edge security features. The large developer community operates in an agile mode and has the ability to proactively identify and fix problems. Due to its extensive ecosystem of libraries, tech stacks, frameworks, and other tools, Java provides more room for experimentation and creativity.
Future of Java
Java keeps evolving. The preferred language for artificial intelligence (AI) projects is now Java. AI projects need powerful processing power, which Java can offer. Strong AI applications like computer vision and natural language processing can be made with Java. Java is used to create business applications like supply chain management, customer relationship management, and enterprise resource planning. It is also utilized in cloud-based services like infrastructure as a service, software as a service, and web hosting. Moreover, Java is employed in deep learning and other machine learning projects. Heavy processing power is needed for this kind of application, which Java can deliver. Java can be used to create software for computer vision and natural language processing. Overall, Java's future appears promising. Many developers love it because of its adaptability, scalability, and capacity to manage a range of development projects.

Hiring Model Types
Let’s explore each recruiting model in-depth, weighing its benefits and drawbacks to help you choose which is best for you and your project.Freelance
Hiring Java web developers can be done by conducting a search on freelance marketplaces. Due to the recent influx of freelance Java developers into the IT industry, this hiring model is becoming more and more common. You need to start your search by entering relevant criteria into freelance websites.
The primary benefit of hiring freelance Java Developers is the substantial cost savings. This is due to the fact that freelancers' median hourly rates are lower than those of in-house Java experts, and you can save money by avoiding costs like labor, taxes, office maintenance, and other related costs.
The most crucial drawback of this recruitment strategy is the high possibility of running into an unqualified specialist. When anything goes wrong, Java freelancers are hardly ever accountable and may disappear. Deadlines are frequently missed because there is no way to monitor their work, which greatly increases the risk to the project. Due to the need to spend time and money looking for a replacement, these circumstances may result in additional costs.
In-house
An in-house Java developer is a full-time Java developer who works for your company. This individual works for your business, goes on trips, spends time in the office, etc. One of the most widely used recruitment models exists today. This method of hiring a developer is possible through job-posting websites like Dice, social media platforms like LinkedIn, or through a staffing firm.
The high costs of this model are its main drawback. In addition to their salary, having a full-time employee also entails additional expenses. You must also account for paid vacation time, leave requests, insurance, taxes, workstation fees, and other costs to create the required working environment. However, if you require a Java developer to be a permanent member of your team, this model will work for you. However, if you only require a worker for a brief time or a specific Java-based project, you should select a different strategy, which we will go over below.
Outsourcing and outstaffing
The outsourcing model of Java development presupposes that you contract with an outsourcing firm to handle all of your work or just a portion of it. Likewise, if your project requires object-oriented development. In this scenario, your vendor will manage the entire process, the entire team, and be in charge of the outcome. For both large and small businesses, outsourcing Java development work has many benefits. If we look at Deloitte, cost savings, flexibility, and quicker project launches are the main benefits of using this recruiting model.
Outstaffing, is a variation of outsourcing, where you also apply to a third-party firm. However, you prefer to extend your team for a while by hiring one or more offshore Java developers rather than allocating a specific amount of work. The fact that you have control over the management and development of the team is one advantage of this model over outsourcing. By having a clear understanding of how the product will be implemented, you can influence the project's pace and flow.
There is one more hiring option, which unites all the benefits of models before.
