Java Features - Why Java Is So Important

features of java


Java is a useful programming language. It enables the creation of a wide range of programs that may operate on a single machine. Java, which just celebrated its 25th anniversary in 2020. It has been improving its programming efficiency for decades.

The creation of Java was with versatility in mind. Thus, allowing programmers to write code. So, it can run on any machine or device, regardless of architecture or platform. It is one of the most useful programming languages on the planet. It was made to function on any system.

According to its home page, Java is to develop apps on more than 1 billion computers. Also, 3 billion mobile phones throughout the world.

It is still one of the most useful coding languages on the planet. Many big MNCs and startups rely on it to power their products. Stack exchange and stack overflow have a lot of discussion threads about it right now. Why is this the case when there are so many languages? They are simpler to learn and use? Such as Python? The answer can find in the Features that we will look at now.

What is Java?

Java is a high-level programming language. It is concurrent, general-purpose, object-oriented. Further, it relies on classes. It consists of the JRE. As a result, it comprises the JVM, which is at the heart of the Java platform.

It's like C++ in that it has a lot of built-in abilities. It is compatible with a wide range of operating systems and is free to use.

Also, it has a feature called concurrency. It allows users to run many statements rather than sequentially.

It's a cross-platform language. As a result, it is useful on any machine that supports it.

It's a well-known computer platform that allows for secure application development.

How did Java become so popular?

It has exceptional features. So, Java has become a popular and helpful coding language. These features play a vital role in contributing to the success of this language. "Java BuzzWords" is the name for its features.

It officially describes by Sun MicroSystems as having the following features.

Java's Features

The Java Language contains many features. So, it has helped it become so well-known in the IT sector. Let's examine its features:


It is one of the most specific programming languages. It is easy to learn and master for grasping the concept of object-oriented learning.

There was once a problem with unreferenced objects filling up memory for adept developers. It was one of the first programming languages to introduce the concept of Automatic GC.

Many people were already working with the C++ language before Java. To solve the difficulty of migration, the Java syntax is close to the C++ syntax. So, making it easy for developers to switch from C++ to Java.


One of the main reasons why it is so popular among coders is this. It follows the OOP conventions to a tee. Object-oriented development contains a wide range of ideas. Thus, including Objects, Classes, and many others. This provides developers with a wide range of design options for their programs.

It also has a support system.






Because the developer community includes both Windows and Linux users. So, a programming language's platform independence is critical. The concept of a JVN is in it to do this. It sometimes acts as a write-once, run-anywhere program (WORA). This is where it outperforms the other languages. All languages before generating machine-level code for the specific machine environment. Thus, it was very difficult for engineers to interact when they were working on the same project in various settings.

It stepped in with a software-oriented platform. It consisted of two parts: an API and a Runtime Environment.

When a program compiles, the compiler generates bytecode for that specific program. So, if we reduce the discussion down to the basics.

The bytecode may run on a variety of OS, including MAC and Linux. Thus, making it versatile.


It is portable because it allows you to move the Java bytecode from one platform to another. It does not need any kind of execution.


Java bytecode is "near" to native code. So, it is faster than other classic interpreted coding languages. It is still slower than a compiled language. For example, C++. Because it is an interpreted language, it is slower than compiled languages. E.g, C, C++, and others.

Safe Language

In today's world, everyone's first worry is security. It ensures security by including unique features such as

It eliminates the usage of explicit references.

Unlike other languages, it executes all its programs in its sandbox called the JVM. So, this ensures that any faults or failures do not affect the external operating system. Thus, making it both secure and efficient. By determining the classes that are local to the computer from those that import from other network sources. So, the ClassLoader allocates the classes defined in the application to the JRE.

Malicious code can attempt to access things outside of their authorization domains on occasion. By killing such code, the bytecode validator prevents this.

It can specify which resources a class can use, such as reading data from a drive or writing data to memory. It achieves this with the help of a security manager.


It is a powerful coding language. Does this imply that it can move mountains? Yes, metaphorically. It achieves this by including many intriguing elements, among which are the following:

It makes extensive use of memory management mechanisms. So, to ensure that there is no room for incorrect memory assignment during execution.

Malicious programs can use explicit pointers to reach code. It is not for sensitive data. As a result, pointers are not present in it.

The problem of unreferenced objects clogging memory is no longer an issue. Before, there was a significant issue with unreferenced objects remaining in memory. Thus, resulting in memory waste. But, with the intro of its garbage collector, the problem is no longer an issue. So, as it searches the heap memory for things. They are no longer useful by the application and discarding them.

The phrase "I ran into an error and my compiler closed immediately" was a big difficulty for developers working on apps. When software crashed or reported an issue, it integrated the idea. It allowed users to execute and perform custom actions.

Neutral Architecture

The architecture of development environments was not unaffected by primitive languages. C, for example, had distinct datatype sizes for 32-bit and 64-bit computers. Many other languages followed suit.

Java chose to be platform agnostic. Thus, resulting in a significant gain in union efficiency. It does not compile to platform-specific bytecode. Instead, it compiles to platform-independent bytecode. This means that the created class file can now operate on a variety of machines with a variety of settings and OS. So, with the sole need that each machine have a JVM. As a result, it is a coding language that is both robust and adaptable.


Because of its inherent closeness to native code, Java's bytecode makes it much faster than other languages. Native code is processor-specific code. So, this means it is to execute on a certain processor, such as Intel's x86 class processor.

For quicker speed, Microsoft's Intermediate language and Java Bytecode have native code for running an in-time compiler.

Because it is an interpreted language, it is slower than compiled languages such as C and C++.

Although it is faster than many other languages. E.g., Python. So, this is an abstract term. Because Python takes less time to build due to its syntax and easily produced code design.


It allows for multithreaded programming. So, this allows for many actions to perform at the same time. A thread is thought of as a single operation or a section of a program that uses the CPU. It improves performance. Thus, by reducing the amount of time it takes to construct a piece of software.

The code for a certain piece of software gets more efficient. The expense of maintenance decreases. But, because individual processes use memory efficiently. So, all these processes share the same memory slots.

Multiprogramming is a gift to the development community. Because a multiprocessor may execute many threads at the same time. It is a super-efficient language since it covers all these aspects.


The fundamental benefit of multithreading is that it allows for the most efficient use of resources.

Each thread does not take up memory. It has a shared memory space.

It is not necessary to wait for the application to complete one activity before moving on to the next.

The cost of maintenance has lowered. It also saves you time.

It boosts the efficiency of complex apps.

Distributed Language

When compared to the specific definition of a distributed system, it isn't distributed. It is to transfer and run programs from faraway computers on local PCs. It allows you to design and support web services using third-party libraries. Further, it's a language paradigm on rules. It only loads/invokes objects or functions when they need by the program. During runtime, it completes invoking instructions. Runtime polymorphism, or function overriding, is an example.

Some of the programs that are useful in distributed apps are RMI and EJB. RMI stands for Remote Method Invocation. It can, as the name implies, call methods running in different JVMs. Further, it shares with a skeleton and a stub. EJB, but, stands for Enterprise Java Bean. It aids in the development of scalable, secure, and reliable apps.

The Dynamic Nature

It's a language model based on needs. The classes aren't all loaded at the same time. They only take action when an invoke operation performs or when data about the class is necessary for memory. During runtime, it completes invoking instructions. Runtime polymorphism, or function overriding, is an example.


The "Java buzzwords" are an essential part of any Java overview. It is a programming language that takes features from C and C++. It polishes them to improve the present programming situation.

We get how strong Java features contribute to its popularity among developers and users. As a result of this essay, it is evident that significant firms use it

It provides features that enable smooth programming for a large scalable architecture. These factors are more than enough to justify their relevance.

We learn at the end of the blog that it is a basic yet efficient and powerful coding language. As a result, it continues to be useful in the development community today. We can use it to create a variety of useful programs. As we go deeper into its multitude of goods. So, it will become clear why it is still one of the most useful programming languages today.
