One of the most used and well-liked programming languages is Java. Even while Java has a tonne of capabilities, it yet manages to be straightforward and flexible, allowing developers to pick it up fast and get to work on java projects with ease. Java is a common programming language because of its ability to be written on one system and executed on a number of others. Here, we'll go into depth about the top ten Java programming features.

Features of Java Programming Language
Platform Independent
A platform-neutral language is Java. Java source code (.java files) are converted to bytes by the compiler (javac) (.class file). The bytecode generated by the compiler is executed by JVM. Any platform, such as Windows, Linux, Mac OS, etc., may run this byte code. This implies that an application created for Windows may operate on Linux and vice versa.
The output that JVMs produce after executing bytecode varies depending on the operating system, although it is the same for all operating systems. Java is referred to as a platform agnostic language for this reason.
Secure
One of the main issues with programming languages is security since these languages are used to create some of the most sensitive and important applications that require security, such banking apps. Java is more secure than C/C++ because pointers cannot be created by developers, making it impossible to access a variable from the outside if it hasn't been initialised.

In Java, there are no pointers and accessing an out-of-bounds array results in an ArrayIndexOutOfBoundsException. Because of this, Java cannot be used to exploit certain security weaknesses like stack corruption or buffer overflow.
Object-Oriented Programming language
A method of organising programmes as a collection of objects, each of which represents an instance of a class, is known as object-oriented programming.
Distributed
Java is a computer language that allows us to build distributed applications. Java distributed applications are made using RMI (Remote Method Invocation) and EJB (Enterprise Java Beans).
Simply put: Java applications may be distributed over several systems that are linked to one another via the internet. Procedures on a remote JVM can be executed by objects on a local JVM.

Multithreading
Java has multithreading capability. Java's multithreading functionality enables the concurrent execution of two or more application components for optimal CPU utilisation.
Portable
Java code created on one system may, as was already said, execute on another. Java code is portable because it can run on any platform thanks to platform agnostic byte code.
Architectural Neutral
Since Java is a platform-independent language, programmes created in it may be run on any machine, regardless of its operating system, and vice versa. Java adheres to the "Write once, run anywhere" philosophy.
The byte-code generated by the compiler from the java file is machine independent, but the java virtual machine can simply translate it into machine-specific code. Java is now an architecturally neutral programming language as a result.
Dynamic
A dynamic programming language is Java. Using the idea of method overriding, OOPs enables developers to edit methods without altering the original method code. They may also add new classes to existing packages and methods to existing classes.
With all of these characteristics, Java is dynamic. Additionally, it enables on-demand loading of classes. Additionally, it supports C and C++ functions from its native languages.

Conclusion
The WORA (Write Once, Run Anywhere) principle and Java's system independence as a design principle have both been discussed in this article. In addition, we discovered what makes Java different from other programming languages. By now, you must have had a glimpse of Java. In addition to all of this, we also discussed problems with C++ that Java has resolved.
