What is JAVA Programming Language and How is it Beneficial in making a Career in it?

Java Online Training | Java Training in Noida | Java Training in Delhi

James Gosling and his team had designed the programming language called Java. Java is a robust, concurrent, and high-level, and object-oriented programming language. Let’s know about JAVA Programming Language in detail, including history, features, Java Online Training, etc.

1. History of Java

The Java programming language project was started in the early ‘90s. James Gosling, who is known as the father of Java, developed Java in 1995. Today this programming language is used in games, e-business solutions, mobile devices, internet programming, etc. Oracle Corporation developed the Java programming language. James Gosling and his team had created Java at Sun Microsystems, Inc. They wanted to design a new language that would permit customer electronic devices to interact with one another. Work on the language started in 1991, and Java made its first appearance on May 23, 1995.

2. Features of Java

a. Simple: 

Java programming language doesn’t use complex and difficult features like goto statements, explicit pointers, multiple inheritances, and storage classes that are used in other programming languages like C and C++.Java is very simple and easy to understand.

b. Platform Independent: 

The biggest strength of Java is its facility of portability which is provided by its significant feature of platform independence. The platform independence feature allows a program that was compiled on one machine to be executed on any other machine in the world. This is possible because Java uses the concept of byte code.

c. Object-Oriented: 

Java supports some of the major object-oriented programming features like Encapsulation, Inheritance, and Abstraction.

d. Robust: 

Java supports automatic garbage collection and can handle runtime errors; all these make it robust.

If you are thinking of starting your career as a Java developer, then start Java Training in Noida online or offline from any well-known institute.  

3. Garbage Collection in Java:

Java garbage collection is the system by which Java programs carry out automatic memory control. The bytecode is compiled by the Java programs run on a Java Virtual Machine (JVM). The garbage collector searches for the objects that were not used and deletes them to free up memory space. Unreferenced objects in Java are called garbage. In this process, the objects that were unused during runtime are reclaimed automatically. Java uses four types of garbage collectors: Serial Garbage Collector, Parallel Garbage Collector, Concurrent Mark Sweep (CMS) Garbage Collector, and Garbage First (G1) Garbage Collector.

4. Java Hello World Program

The conventional Java “Hello World!” program code is as follows:

HelloWorldApplication.java

Public classHelloWorldApplication

{

Public static void main(String args[])

{

System.out.println(“Hello World!”);

}

}

  1. Source files in Java contain a public class. The source file is named after the public class name and ends with the suffix .java for example, it is HelloWorldApplication.java.
  2. The code must be compiled into the bytecode, creating a file named HelloWorldApplication.class. Only then can it be launched.

Iii. Only one public class is allowed in the Java source file, but it can contain any number of public inner classes.

  1. If the source file contains multiple classes, make one class public and name the source file after the public class name.

Conclusion –

Java is one of the demoing languages in the programming industry, so there is no doubt that it has a bright career opportunity. ShapeMySkills Pvt Ltd is the best institute to do Java Training in Delhi, so kick-start your career as a software programmer.
