What is Java? A Beginners’ Guide.

Java is a popular programming language. The language was invented by James Gosling and developed by Sun Microsystems. It was released in the year 1995.

Today’s Internet is absolutely saturated with Java-run programming. We have Java to thank for many of the applications that make day-to-day living easier. Java is currently owned by Oracle.

Let’s try to get a better understanding of what Java is all about.

What is Java?

Java is an object-oriented programming language. It has a virtual machine platform that allows you to create compiled programs that run on nearly every platform. 

Java is quite similar to C++. However, it has more advanced and simplified features. Java is concurrent, where you can execute many statements instead of executing them sequentially. It is an independent programming language which lives up to its motto of “Write once, Run anywhere.” This is because the compiled code can run on any platform, given that it supports Java.

Java program has file extension “.Java” and translates source code into bytecodes which is executed by JVM(Java Virtual Machine). It also uses more memory.

So, in other words, Java is a computing platform in which you can develop applications.

What is Java Used For?

Java is used in a wide range of places, including Android apps, credit card programming and in the creation of desktop applications and web enterprise applications.

Why Learn Java?

1) Java is a platform-independent language. We can write Java code in one platform and run it in another platform

2) Java is a general-purpose language with a wide range of applications. It’s used for developing mobile and desktop applications, big data processing, embedded systems, and so on.

3) Java is an object-oriented programming language. It helps in code reusability.

Java Platforms

There are three key platforms which are used to create Java applications. These are as follows:

a) Java SE

Simple, stand-alone applications are developed using Java Standard Edition.

b) Java EE

The Java Enterprise Edition, provides the ability to create server-side components that can respond to a web-based request-response cycle.

c) Java ME

 Java also provides a lightweight platform for mobile development known as Java Micro Edition.

What are the Benefits of Using Java?

The benefits are highlighted below:

1) It is a straight forward programming language that allows you to use, write, compile, debug and learn in a simple manner.

2) Java runs on any machine that has JVM. No other special software is required.

3) Java has no explicit pointer. Apart from this, it has a security manager that defines the access of classes.

4) Java can keep information and restore it easily.

5) It helps in developing applications on networks that can contribute to both data and application functionality.

6) Java opens doors to the learning of other programming languages. There are lots of programming languages which are similar in construct to Java.

7) There are hundreds of thousands of people programming in Java on a daily basis who are willing to help newcomers.

8) Java is the most widely used programming language in the world. 

What are the Cons of Using Java?

The cons of using java are highlighted below:

1) Java is memory consuming and comparatively slower.

2) The default look of GUI applications written in Java using the Swing toolkit is very different from native applications.

3) There is no control over garbage collection in Java. That is a programmer does not have any right to control the garbage collection.
