What Are The Features Of The Java Programming Language?

One of the most used and well-liked programming languages is Java. Even while Java has a ton 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 well-liked option in the programming industry since it allows for the flexibility of creating code on one system and running it on a number of different machines.

Additionally, the frequent upgrades make it a secure and reliable option for projects that plan to last for a longer time. Java BuzzWords is another name for the Java features.

According to the Oracle website, Java is the most popular programming language and development environment, with more than 51 billion Java Virtual Machines being used worldwide by millions of developers.

Features of Java

The following are some of Java’s beneficial and sophisticated features:

1. Simple

Java is an extremely basic programming language that is straightforward to understand, write, and learn. Java has clear and simple-to-understand syntax.

In comparison to other widely used programming languages, Java is easy for the following reasons:

  • Java is easier to learn if one is familiar with C or C++ since the two languages’ syntaxes are comparable. The intricate features of C and C++, such as pointers, go to statements, preprocessors and header files, multiple inheritance, operator overloading, etc., are not used in Java.
  • Since Java has automatic garbage collection, there is no need to manually destroy items that are not referenced.

2. 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.

Although each operating system uses a distinct JVM, they all give the same results when bytecode is executed. Java is referred to as a platform agnostic language for this reason.

3. Secure

Security is one of the primary problems in programming languages since these languages are used to develop some of the most sensitive and significant applications that must be safeguarded, including banking apps. Because Java bans the formation of pointers, it is more difficult to access an uninitialized variable from the outside, making Java more secure than C/C++.

There are no pointers in Java, and an ArrayIndexOutOfBoundsException is thrown when accessing an out-of-bounds array. Java cannot be used to exploit some security flaws like stack corruption or buffer overflow because of this.

4. Object-Oriented Programming language

The method of structuring programs as a collection of objects, each of which represents an instance of a class, is known as object-oriented programming.

There are 4 key ideas in object-oriented programming:

  1. Abstraction
  2. Encapsulation
  3. Inheritance
  4. Polymorphism

5. Robust

Reliable means robust. Because early error detection is highly valued in the development of the Java programming language, the Java compiler is able to identify mistakes that are difficult to see in other programming languages.

The primary characteristics of Java that make it reliable are:

  1. Garbage collection,
  2. Exception Handling
  3. Memory allocation.

6. 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 distant JVM (java virtual machine) can be executed by objects on a local JVM.

7. Multithreading

Java has multithreading capability. Java’s multithreading functionality enables the concurrent execution of two or more application components for optimal CPU utilization.

8. 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.

9. Architectural Neutral

Since Java is a platform-independent language, programs 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.

10. 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.

11. Performance

Compared to other conventional interpreted programming languages, Java is considerably quicker. Java code that has been compiled into byte code, sometimes referred to as machine code, provides for a quicker execution. Java utilizes a Just in Time compiler, which may run code when needed. This enables Java to just run the methods that are being called, which accelerates performance.

Java also makes advantage of the multithreading notion, which enables the simultaneous execution of many pieces of code. High performance is delivered by this.

It is still somewhat slower than a compiled language (like C++), for example. Java is slower than compiled languages like C, C++, etc. since it is an interpreted language.
