Java is an advanced, object-oriented, class-based programming language. It uses a straightforward programming language. Programming is simple to write, compile, and debug because of Java. It facilitates the development of modular programmes and reusable code. If you are here to know How Java Works internally? You can Join Java Training In Chennai at FITA Academy for the best coaching from industrial experts.
Java was designed as a general-purpose programming technology so that programmers could generate just one executable file that runs on all systems that support Java, to have as few implementation dependencies as possible.
Java Features
Here are some important Java features:
- High-Performance programming is used in it.
- One of the simplest programming languages to learn.
- If you write code once, it will run on almost any computing platform.
- It is a programming language that is secure.
- It is intended for use in the distributed environment of the Internet.
Components Of Java
Java Development kit (JDK)
Java programmes and applets are developed using the JDK software development environment. The Java Development Kit is the full form for the JDK. Java development is supported on Windows, Linux, Mac OS X, and Solaris. By using the JDK, they can create and execute Java programmes.
Java Virtual Machine (JVM)
A Java Virtual Machine (JVM) is an engine that offers a runtime environment for Java programmes or code. Machine language is created from Java bytecode. A component of the Java Run Environment is the JVM (JRE). Other programming languages produce machine code for a particular computer through the compiler.

Java Runtime Environment
A JRE is a programme created to execute other programmes. Class libraries, loader classes, and JVM make up this system. To put it simply, JRE is required if you wish to run a Java programme. You just need to instal JRE to run Java programmes if you are not a coder.
Classes, Procedures, and Variables in Java
- You must define a class name in Java whenever you create a new programme. This is everything you ought to know if you are a beginner.
- But once you’ve learned the fundamentals of variables and methods, you’ll want to learn more about OOP, classes, and some more complicated subjects.
- Let me first explain that classes are essentially objects. or rather, a guide to the things that make them all distinct.
- Variables correspond to an object’s state, while methods refer to its behaviour.
- You will only utilise the main class while you begin to learn Java. However, you’ll discover that many classes interact with one another as you master the fundamentals and OOP.
- The behaviour of an object is described by its method.
- As a result, when objects communicate with one another, they are only calling the appropriate method of the relevant object.
Object-Oriented Programming
Java is regarded as an object-oriented programming (OOP) language with many uses. General purpose describes Java’s extensive functionalities. Java allows you to accomplish anything.
An object in OOP is comparable to an actual object. It may be used to describe a person, location, or thing. If I were an object in a programme, I would have two arms and two legs, and these qualities might be expressed as data types.
