What is java? And Features Of Java

In this blog, we will discuss what is java and the features of java. So, let’s get started.

Java has been around for decades, but many small business owners have never tried to learn it. And also many international students who are doing java courses, are not able to understand this language. Because they have a busy schedule, that’s why they need java exam help and java homework help from professional experts who can provide them with high-quality work. 

It is an important language to learn for web developers and for programmers. If you have never been on a team that has used Java, then you may have a lot of questions about it. Here are the answers to some of the most common questions about Java. 

What Is Java?

It is a computer programming language. Java allows programmers to write computer instructions using English commands instead of writing them in digital code. It is known as a high-level language because it can be easily read and written by humans.

Like English, Java has a set of rules that determine how instructions are written. These rules are known as their syntax. After a program is written, high-level instructions are translated into numerical digits, which the computer can understand and execute.

Who made Java?

In the early 90s, Java, which originally went under the name Oak and then Green, was created by James Gosling on a team for Sun Microsystems, a company now owned by Oracle.

It was originally designed for digital mobile devices, such as cellphones. However, when Java 1.0 was released to the public in 1996, its main focus shifted to use on the Internet, providing users with a way to create animated web pages that interact with users. 

However, several updates have been made since version 1.0, such as J2SE 1.3 in 2000, J2SE 5.0 in 2004, Java SE 8 in 2014, and Java SE 10 in 2018.

Over the years, It has grown into a successful language for use on and off the Internet.

Features of Java

The primary objective of the Java programming language creation was to make it a portable, simple and secure programming language. Apart from this, some outstanding features play an important role in the popularity of this language. You can also say java buzzwords to java features.

Below is a list of the most important features of the Java language.

Easy

It is very easy to learn, and its syntax is simple and clean. According to Sun, the Java programming language is simple because:

• Its syntax is based on C++ (so it is very easy for programmers to learn java after C++).
• It removed many complex and rarely used features such as explicit pointers, operator overloading, etc.
• Being an automatic garbage collection in Java, there is no need to delete unrecognized objects.

object-oriented

It is an object-oriented programming language. Everything in Java is an object. Object-oriented means that we organize our software to combine different types of objects that comprise both data and behaviour.

Object-oriented programming (OOPs) is a methodology that simplifies software development and maintenance by providing certain rules.

The basic concepts of OOP are:

• Object
• Class
• inheritance
• Polymorphism
• Abstraction
• Encapsulation

Platform-Independent

It is platform-independent as it is different from other languages ​​like C, C++ etc which are compiled in platform-specific machines whereas Java wrote can run anywhere. Its code can be run on multiple platforms, for example, Windows, Linux, Sun Solaris, Mac OS, etc. Its code is compiled by the compiler and converted into bytecode. This bytecode is a platform-independent code because it can be run on multiple platforms, i.e. Write Once and Run Anywhere(WORA).

Safe

It is best known for its security. With Java, we can develop virus-free systems. It is safe because:

• no visible pointer
• Its programs run inside a virtual machine sandbox
• ClassLoader: The class loader in Java is a part of the Java Runtime Environment (JRE), which is used to dynamically load Java classes into the Java Virtual Machine. It adds security by isolating packages for classes on the local file system that are imported from network sources.

Conclusion (what is java)

In this blog, we have discussed what is java and its features of java. java is a high-level programming language first released by Sun Microsystems in 1995. It is a programming language that can be used to run applications online or offline. We hope you understood easily.
