Java is a high-level, object-oriented programming language developed by Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. It was designed to be platform-independent, meaning that Java programs can run on any device or operating system that has a Java Virtual Machine (JVM) installed. This portability is achieved through the principle of “Write Once, Run Anywhere” (WORA), where developers can write code once and deploy it on multiple platforms without modification.

Some key features of Java include:

1. Object-Oriented: Java is based on the object-oriented programming (OOP) paradigm, which emphasizes the use of objects to represent data and behavior.
2. Platform Independence: Java programs are compiled into an intermediate bytecode format, which can be executed on any device or operating system that has a compatible JVM.
3. Automatic Memory Management: Java uses automatic garbage collection to manage memory, relieving developers from manually allocating and deallocating memory.
4. Robustness: Java includes features such as strong typing, exception handling, and memory management, which contribute to the overall robustness and reliability of Java programs.
5. Security: Java’s security model includes features such as bytecode verification, sandboxing, and access controls to protect against malicious code.
6. Rich Standard Library: Java comes with a comprehensive standard library that provides support for a wide range of tasks, including input/output operations, networking, database access, and more.

Java is widely used in various domains, including web development, mobile app development (Android), enterprise software development, scientific computing, and more. It remains one of the most popular programming languages in the world due to its versatility, performance, and community support.

Components of Java

There are three primary elements in Java, the Java programming language, which includes:

1. Abstraction – Abstraction is the process of displaying relevant information and hiding the details that are internal or behind the scenes. In the following example to allow a student to be admitted to a college, the information required will be name address, address, parents’ name as well as high school marks. Particulars like favorite foods, sports, or even movies aren’t relevant.
2. Encapsulation – It is the same as capsules. The entire source code as well as the entire information are bundled into one single unit. All variables and methods are stored under the same classification name. only the identical class object can be used by it.
3. Polymorphism- Polymorphism refers to the fact that a particular task can be accomplished in different ways. One function can be utilized to accomplish different tasks. In the case below Method Draw() is a function that can be utilized at various places to draw various shapes, such as a rectangle, triangle, or circle.
4. Inheritance – If a class inherits characteristics and attributes from other classes, this is called inheritance. There’s always a superclass as well as a subclass. Subclasses inherit attributes of the superclass. In the following example, the animal is a superclass that includes attributes like eating() as well as sleep(). Subclasses of reptiles, mammals, and humans have these attributes.

1. JVM – JVM is the Java Virtual Machine or JVM is an independent platform Java component that offers an environment to run Java programs. Therefore, JVM loads the code and validates the code. Then, it executes the program and then provides an environment for running.
2. JRE – It is the Java Runtime Environment or JRE creates an environment where the Java files can be executed and run. It is a program that includes JVM as well as Java class libraries, as well as Java ClassLoader.
3. JDK- It is the Java Development Kit also known as JDK is a subset that is a subset of JRE and is an application development environment that allows you to create Java Applets and applications. The JDK comes with an exclusive JVM as well as several other tools to complete the creation of the Java application.
