Java is a high-level, class-based, object-oriented programming language. At the moment, it is one of the most popular and widely used languages. Java is a general-purpose programming language that can run on all platforms that support Java without the need for recompilation.
Java provides a rich and wide range of API that helps programmers to develop applications. It can be used to develop a variety of applications. For instance, enterprise applications, network applications, desktop applications, web applications, games, android app, etc.
In this article, we will elaborate on the various sections of technology that fall under the applications of Java. The main applications of Java are:
- Mobile App Development
- Desktop GUI Applications
- Web-based Applications
- Game Development
- Big Data Technologies
- Distributed Applications
- Cloud-based Applications
- IoT Applications
Mobile App Development
The Java programming language is widely regarded as the standard for mobile app development. It is used to write a majority of Android applications. Android Studio, the most popular android app development IDE, also uses Java to construct Android apps.
As a result, if you are already comfortable with Java, developing Android applications will be considerably easier. Java has been used to create the most popular Android apps, such as Spotify and Twitter.
Desktop GUI Applications
With tools like Abstract Windowing Toolkit (AWT), JavaFX, and Swing, Java can construct graphical user interfaces.
A list, a menu, and a button are all pre-assembled elements in AWT. Swing, on the other hand, is a GUI widget package with extensive features. Scroll panes, tabbed panels, trees, tables, and lists are examples of these features. It is one of the most effective applications of Java.
It’s also used to create web-based applications, because of its extensive support for web development via Servlet, JSP, and Struts. Hence, Java is also called a server-side programming language. We can create a wide range of applications using these technologies.
Spring, Hibernate, and Spring Boot are the most popular frameworks for constructing web-based applications. Popular websites that use the Java programming language include LinkedIn, AliExpress, etc.
Developers utilize Java to create a variety of apps for social security, insurance, health, and education because of its high security and ease of coding. It is one of the most effective applications of Java.
Game production companies generally use Java for programming. The most powerful open-source 3D engine supports Java. When it comes to building 3D games, the engine has unrivaled capabilities.
Minecraft, Mission Impossible III, and other Java-based games are among the most popular. For game development, some well-known frameworks and libraries are available, such as LibGDX and OpenGL.
Big Data Technologies
Although there are other programming languages available for Big Data Technology, Java remains the most popular. Java creates the Hadoop HDFS platform for processing and storing large data applications.
Java is commonly used in big data ETL solutions like Apache Camel and Apache Kafka. It’s utilized in large data contexts to extract, manipulate, and load data.
JINI (Java Intelligent Networking Infrastructure) provides the infrastructure for registering and finding distributed services that meet its requirements. JavaSpaces is a mechanism that it implements. It allows items in a network to be distributed, persistent, and migrate.
A cloud application is an internet-based application that provides on-demand access to IT resources. The service is provided at a minimal cost thanks to the cloud-based application. Java provides the framework for building cloud-based apps.
We may utilize Java to create SaaS (Software as a Service), LaaS (Logging as a Service), and PaaS (Platform as a Service) applications (Platform as a Service). The cloud application is commonly used to share data across businesses or to develop apps from afar.
Internet of Things is a technology that connects and communicates with the gadgets in its network. Moreover, all small devices can work with IoT. For instance, health monitors, cellphones, wearables, smart lighting, televisions, and so on.
Java gives developers an unrivaled advantage to construct IoT applications. Java is popular among IoT programmers because of its security, adaptability, and versatility.
Advantages and Disadvantages of Java
Simple and easy-to-use
Java is a simple programming language that is simple to learn and comprehend. It has a C++-like syntax and employs automatic garbage collection, so we don’t have to worry about removing unreferenced objects from memory.
Java has also removed the features like explicit pointers, operator overloading, etc., making it easy to read and write.
Java uses an object-oriented paradigm, which makes it more practical. Everything in Java is an object which takes care of both data and behavior. Java uses object-oriented concepts like object, class, inheritance, encapsulation, polymorphism, and abstraction.
Because it does not employ explicit pointers, Java is a secure programming language. Java programs also execute inside the sandbox of the virtual computer.
JRE also includes a classloader. It dynamically loads classes into the JVM. It distinguishes between the local file system’s class packages and those imported over the network.
Because of its strong memory management, Java is a resilient programming language. We can also utilize type checking to improve the security of our code. It lacks explicit pointers, preventing the programmer from accessing memory directly from the code.
Java can execute natively on many platforms, so we don’t have to build it every time. It is a WORA (Write Once, Run Anywhere) language. Byte code is a platform-agnostic programming language that can run on a variety of platforms.
Firstly, Java employs a multi-threaded environment. We can split large tasks into multiple threads and execute them independently. The fundamental benefit of multi-threading is that we don’t have to allocate memory to each active thread.
We need to interpret Java during runtime. Hence, it can run on every operating system. However, it makes it perform slower than the languages like C and C++. On the other hand, each operating system needs to compile the C++ program. Thus, the code runs faster.
Java program consumes more memory since it runs on top of Java Virtual Machine (JVM).
Because of its greater processing and memory requirements, the Java programming language is a bit costly. To run the Java software, we’ll need more powerful hardware.
Less machine interactive
Because Java lacks explicit pointers and lacks the ability to communicate directly with machines, it is less suitable for the software that has to run rapidly and directly with the machine.
Java has an automatic garbage collector. The programmer cannot control it. It doesn’t provide the methods like delete() and free() to free the memory.
