Java is an object-oriented language for programming that originates in both of C in addition to C++. In C, Java takes its format , while taking the object-oriented programming that comes from C++. In order to master Java from beginning to finish, a person who is proficient in C/C++ would be able to comprehend.

Thus, we can define Java as an
- Simple
- Extremely robust
- Object-oriented
- A secure programming language.
Hardware components or a software environment within which software runs is refer to as”platform. “platform”. Java includes a Java Runtime Environment (JRE) that runs on it. Therefore, Java is also an operating system.
We will explore more details about Java as an application platform in our next tutorials.
At present, Java programming language is the most widely use programming language to develop client-server web applications on the internet with around 9.9 million Java developers using Java.
Java Features
Let’s look at some of the distinct characteristics that are unique to this Java programming language.
1.) Easy: Java syntax is quite simple and easy to comprehend. Java is also simple to master. The majority of features in C++ that were either confusing or unclear can be simplify with Java and some are even omitted.
#2) Secure: Java program runs within the Java Runtime Environment (JRE) which is secure. The JRE is not interoperable with the OS of the system, which means Java programs are not interfering in any way with system. In addition it is the case that the Java language comes with security capabilities that let us create secure, virus-free applications. This is why so many banking applications are built using Java.
3.) The robust: Java introduces automatic garbage collection and handling of exceptions that assists in preventing any possible mistakes. Java additionally focuses on run-time and compile time error detection. All these features make programs/applications developed in Java more robust.
#4) Portable: Portable Java program that is compile into Byte code is able to executed on any platform. It is implementation-independent and everything require to run the code like storage, data types, etc. are predefined.
#5) The object-orient language: Java is a pure object-orient programming language. Every aspect of Java can be describe as an object. The features of the language can be easily extend since it is an model based on objects for programming. Java language is compatible with all important features of Object-oriented programming.
#6) Platform-independent: Java is a “write once, run anywhere” code. In contrast to other programming languages that convert into machine-specific code Java is written as an byte code that is able to run on any computer regardless of operating system. Any computer that has the Java Runtime Environment (JRE) can run this code.
#7) Multithreaded: Java’s multithreading function allows Java applications to execute several tasks at once. Furthermore, multiple threads use the same memory as well as other resources to complete tasks at the same time.
#8) Distributed: With Java we can create distributed applications that utilize sophisticated Java concepts such as Remote Method Invocation (RMI) and Enterprise Java Beans (EJB).
We can then disperse the Java program to different computers connected to an internet i.e. an object running on one machine is able to perform remote operations on a remote machine.
These are the key characteristics of Java that make it one of the most popular and highly sought-after programming language in the present.
Let’s look at the different applications we can create using the Java programming language.
Java Application Types
Java programming language may be employe to develop the following kinds of applications.
#1) Standalone Applications
They’re also referred to as desktop application base on Windows. They are basically standalone software which can be install on the desktop.
Applications such as media player as well as security software for antivirus, editors on desktops etc. are just a few examples of applications that can use as standalone applications. Java features such as AWT as well as Swing are commonly employe to create these kinds of applications.
#2) Enterprise Applications
Enterprise applications are typically distribute and come with features such as advanced security, load balancers and clustering.
Java gives these capabilities via the enterprise Java Beans (EJB) in addition to the name suggests, EJB utilize to create enterprise-level applications. Banking applications are business applications that are the most well-known.
#3) Web Applications
Web applications operate on the server and generate fluid web pages. The applications must be highly responsive and be able to create web pages in the field. Java features like JSP, servlets, struts, spring, hibernate, etc. utilize to create web applications.
#4) Mobile Applications
Mobile applications are a program design for use on smartphones. Presently, Java ME and Android are the most popular platforms for creating mobile apps.
As a result, we can realize that Java lets us create numerous applications by using its many capabilities. This means that it makes Java the most widely used programming language that remains on top of the list after all these years since its creation. As an engineer, we must not switch between technologies in order to create diverse kinds of applications. You can accomplish almost anything with Java.
