Features of Java Programming Language: Java is a network-centric, object-oriented, multi-platform language that can function as a platform. It is a simple, secure, and dependable programming language that can be used to code everything from server-side technologies and big data applications to business software and mobile apps.  We will explain the most important features of Java programming language in detail. Let’s take a closer look.

Are you considering learning Java programming language? Thinking of questions like what is Java programming language and what are the features of Java? What is the importance of Java? Why Java is a portable programming language? Then, don’t worry; we will answer all your questions in this blog! 

Java is often called the “write once, run anywhere” (WORA) language. It is one of the most popular programming languages in the world. Its simplicity, platform independence, and strong security features have made it a favorite among developers for over two decades. Java’s ability to run seamlessly on different platforms, thanks to the Java Virtual Machine (JVM), is one of its key characteristics of java.  

The language’s object-oriented design makes coding modular and reusable, while features of Java language, like automatic memory management and built-in security, help create reliable and secure applications. With a vast library of tools and frameworks, Java is widely used for web development, mobile apps, and enterprise systems. Supported by an active community and regular updates, Java remains a top choice for beginners and professionals.  

Now, let’s discuss the 8 key features of Java programming language that contribute to its versatility and widespread use in the programming world.   

8 Features of Java Programming Language   

Java programming language offers many features that make it both efficient and effective. Here are some of the key benefits or features of Java programming language :  

1. Simple

Java is a straightforward and easy-to-understand programming language lacking the intricacies of prior programming languages. This is one of the most important features of the Java language. 

Because Java language needs to run on electronic devices with limited memory and resources, simplicity actually served as the design goal. Java has the same grammar as C and C++. Thus, programmers who convert to Java will not have any syntactic issues. Second, the idea of pointers has been eliminated from Java, which confuses programmers and makes pointers vulnerable to security.  

2. Object-Oriented

Java is an object-oriented programming language, which implies that everything in Java is expressed in terms of classes and objects. What is an object, then? The object is only a tangible thing that may be used to symbolize any individual, location, or thing and can be set apart from others. Every nearby object has a state and behavior that are connected to it.   

For instance, the cell phone is a physical object with states such as color, brand, model, and camera quality, all of which are represented by variables. Additionally, mobile is linked to activities like chatting, phoning, taking pictures, and so on, all of which are represented by Java methods.  

We have now seen what an object is and learned about its related state and behavior.    

What is class? A group of objects that share the same state and behavior is referred to as a class. For instance, different manufacturers such as Samsung, Apple, Vivo, Oppo, Xiaomi, and others produce distinct types of smartphones, yet they are all categorized under the same heading: mobile phones. 

3. Platform Independent

The goal of Java developers’ design was to create a language that is compatible with all platforms. In this context, platform refers to a certain kind of hardware technology and operating system. Programmers can utilize Java to develop their programs on any system with any configuration and run them on any other machine with a different configuration.   

This reduces the overhead of programmers writing system-specific code. Now, programmers write programs only once, compile them, generate the bytecode, and then export it anywhere.  This is one of the important features of Java programming.

4. Portable    

The “write once, run anywhere” concept of Java makes it portable since it enables Java code to be turned into a platform-independent bytecode that can run on any device that has a Java Virtual Machine (JVM). This portability is beneficial since it saves developers time and effort by removing the need to build distinct code for every hardware platform or operating system.

Java’s portability makes it an excellent choice for creating software that works seamlessly across various platforms and can be installed on a wide range of devices. All things considered, Java’s portability makes cross-platform development easier and expands the compatibility and reach of apps. 

5. Robust

Because the Java language is robust, it can withstand unexpected program termination. This is due to two factors. Firstly, it features a very useful and significant feature called Exception Handling. Java code will not be harmed if an exception occurs, while other low-level languages will cause the application to crash.   

Java’s memory management capabilities are another factor contributing to its strength. Java offers a runtime garbage collector, provided by JVM, that gathers all unused variables in contrast to other low-level languages.

The garbage collector is a unique JVM program that periodically runs, finds any unneeded variables and objects, and deletes them from the memory to make room.   

For some older languages, however, there is no such program to manage memory; instead, programmers are in charge of allocating and releasing memory spaces; otherwise, the program can fail because of a lack of memory.  

6. Secure

One of the most widely recognized features of Java programming is its strong security, making it an ideal choice for creating secure, virus-free systems. One key reason for its security is that Java programs run inside a virtual machine, which adds an extra layer of protection. Additionally, it uses its own runtime environment called the Java Virtual Machine (JVM), which ensures the controlled execution of programs.  

Java also comes equipped with a security manager that defines what resources a program can access, such as reading or writing files on the local disk. This ensures that unauthorized actions are blocked. Moreover, during runtime, Java uses a class loader to separate local files from those imported from network sources, further preventing potential threats.

Another essential features of Java is the Bytecode Verifier, which checks the code for any illegal or harmful instructions before execution. These built-in security measures work together to make Java a trusted and reliable programming language. 

7. Simplified Syntax

Java is one of the most popular programming languages because of its simplified and easy-to-understand syntax. Java’s structure is simple and easy for both developers and computers to understand. However, it is case-sensitive, so “hello world” and “Hello world” are considered entirely different. 

Java relies heavily on objects and classes, which are the core building blocks of its syntax. Each statement in Java ends with a semicolon (;) to indicate the end of a command. Additionally, curly brackets {…} are used as delimiters to define blocks of code, making it easier to organize and manage programs.

These simple rules make Java an approachable and efficient language for both beginners and experienced developers.  

8. Multi-Threaded

One of the important features of Java programming language is multi-threading. Java supports multithreading, which allows multiple tasks to run at the same time. This improves CPU efficiency and makes applications faster and more responsive. For example, in Google Docs, while you type, spell check and autocorrect run simultaneously.  

A thread is a small, independent part of a program. Multithreading refers to multiple threads running simultaneously.  Servers also use this to handle multiple client requests at once.  

In Java, you can create threads easily by either implementing the Runnable interface or extending the Thread class. This feature of Java makes it ideal for building fast and efficient applications.
