Java Technology And Terminology

Sure! Here’s an overview of some key Java technologies and terminology that are commonly used in the Java ecosystem:

Core Java Concepts and Terminology
Java SE (Standard Edition): The core platform for Java programming, providing essential libraries and APIs for building desktop applications, server applications, and small-to-medium-sized applications.

JDK (Java Development Kit): A software development kit required to develop Java applications. It includes the JRE, an interpreter/loader (Java), a compiler (javac), an archiver (jar), and other tools needed for Java development.

JRE (Java Runtime Environment): Provides the libraries, Java Virtual Machine (JVM), and other components to run applications written in Java.

JVM (Java Virtual Machine): An abstract computing machine that enables a computer to run a Java program by interpreting Java bytecode.

Bytecode: The intermediate representation of Java code, which is executed by the JVM. It is platform-independent and allows Java to be a “write once, run anywhere” language.

Garbage Collection: The process by which the JVM automatically removes unused objects from memory, helping to manage memory and avoid leaks.

Java Syntax and Language Features
Class: A blueprint from which individual objects are created. A class can contain fields (variables) and methods (functions).

Object: An instance of a class. It has state (attributes) and behavior (methods).

Inheritance: A mechanism where one class inherits the fields and methods of another class, promoting code reuse.

Polymorphism: The ability of different classes to be treated as instances of the same class through a common interface. It supports method overriding and method overloading.
