Top 10 Things You Need To Know About Java Programming Language

Summary

From selecting your first programming language to developing applications for Android and a variety of other operating systems, Java has been the undisputed choice. It has long been one of the most popular programming languages among developers, owing to its versatility and interoperability. We are certain that this language must have ignited a desire within you to become a programmer! Learn everything you want to know about Java from its historical evolution to the current market scenario. Let’s dive in!

Today, particularly in the aftermath of a terrible pandemic, the internet and cellphones have become a vital part of our life. We rely on our phones for nearly all of our daily activities. Previously, we shopped at malls, queued at banks, and booked travel through travel agents.

However, we can now do all of this from the comfort of our own homes, courtesy of smartphones. All of this is made possible via Java, a high-level programming language. No wonder Java is in such high demand, and everyone wants to learn Java by taking Java courses.

Here we will dig deep into the fundamentals of Java, its origins, and how it has evolved over time to dominate the programming world today. 

1. What exactly is Java?

Java is an object-oriented language used in distributed computing systems such as those found on the internet.

It is a sophisticated language that is also simple to read and comprehend. It enables developers to "write once, run anywhere," which means that compiled Java code will execute on any Java-compatible systems without requiring a recompilation.

Features:

• Concurrent execution allows you to execute many statements concurrently rather than sequentially.
• A programming language that is both class-based and object-oriented.
• An Independent programming language that adheres to the "Write once, run anywhere" philosophy, which means that compiled code runs on any platform.

2. Java's History

It was created in 1991 by James Gosling and Sun Microsystems. While developing the language, he had a single motto: "Write once; run anywhere." They first called it Oak after the oak tree outside Gosling's office. The name was changed to Green, and then to Java Coffee, after the Indonesian coffee, before being abbreviated to Java in 1995.

3. What Purposes Does Java Serve?

Java is frequently used in:

·        Web consoles

·        Graphical user interfaces (GUIs)

·        Web and mobile application development

·        Game development

·        Embedded systems development

·        Desktop applications development.

Java is also used to create device-specific applications. Not only is it employed in computers and mobile devices, but also in other electrical equipment such as air conditioners, televisions, and washing machines.

Java enables online registration forms, banking applications, and online shopping too.

4. What is Java's foundation?

Java is based on the C and C++ programming languages.

Sun Microsystems built the original Java compiler, which was written in C and included some C++ libraries. Java files are translated to bit code format using a compiler, which is then executed by the Java interpreter. Java code is executed by the Java Virtual Machine (JVM), which serves as the runtime environment.

5. Java Editions

Java is available in three editions. Programmers can choose from any of these editions depending on the type of application they intend to create.

·        Java Standard Edition - Includes the essential libraries java.lang, java. util, and so on.

·        Java Enterprise Edition - This edition includes Java APIs such as JMS, EJB, and JSPs/servlets.

·        Java Micro Edition - This edition is used to develop Java applications for mobile phones, set-top boxes, and handheld devices.

Java SE is the most extensively used edition of Java (Standard Edition). Java SE covers the fundamentals of Java—the majority of applications require Standard Edition.

6. Java Fundamentals

Java's fundamental notions are its object-oriented programming (OOPs) capabilities. OOP simplifies the development and maintenance of software and applications by introducing ideas such as:

·        Object: An object is a discrete element. For instance, a dog can be regarded as an object because it has a distinct color, breed, and name. It is capable of barking and eating.

·        Class: It is a blueprint that can be used to generate an unlimited number of things. Classes are used to organize code in the same way as fruits, vegetables, and pharmaceutical items are classified in a supermarket.

·        Inheritance: is a notion in which one class inherits the characteristics and behavior of its parent class.

·        Polymorphism: is the process of accomplishing the same work in a variety of different ways. It enables programmers to use the same word in a variety of contexts.

·        Abstraction: In Java, abstraction is used to obscure internal details and display only the most critical ones.

·        Encapsulation: this means combining or wrapping code and data into a single unit (similar to a capsule). Encapsulation is demonstrated using a Java class.

7. Java Advantages

Java possesses a number of characteristics and traits, including the following:

·        The straightforward syntax is extremely simple to comprehend and master.

·        Java is a strong programming language.

·        Java has capabilities such as garbage collection and error management.

·        Java is a platform-independent language.

·        Java is a secure programming language that supports multitasking.

·        Java is not as quick as C or C++, but it outperforms all other languages.

After discussing the various characteristics of Java, let's examine the various components of the Java programming language.

8. Java’s Components

The Java programming language is composed of three major components:

·        JVM: JVM, is a platform-independent Java component that provides an environment in which Java programs can be executed. As a result, the JVM loads the code, validates it, executes it, and offers a runtime environment.

·        JRE: JRE creates a platform for running and executing Java files. It is a software bundle that includes the Java Virtual Machine, as well as Java class libraries and a Java class loader.

·        JDK: JDK is a superset of the Java Runtime Environment (JRE). It provides a software development environment for creating Java programs and applets. The JDK comes with a private JVM and a few more resources necessary to complete the creation of a Java program

9. How to Become a Java Expert

Java is used widely, owing to Java's inherent versatility, dependability, and compatibility. Thus, it is a necessary talent to possess if you wish to pursue a career in programming. To help you start, here are some pointers:

·        Begin with the fundamentals of Java programming (variables, data types, conditional statements, arrays, loops, functions).

·        To grasp the fundamental concepts of Java programming, read a book on the subject.

·        Acquaint yourself with sophisticated themes (object-oriented programming, inheritance, abstract class, Java interface, collections, abstract classes, exceptional handling, wrapper classes).

·        Regularly practice coding in order to get experience.

Stay current on Java by reading articles and updated documentation.
