  • Class: A class is a template or blueprint for creating objects. It defines the properties and methods of the object.
  • Object: An instance of a class. Objects have properties and methods that are defined by the class.
  • Method: A function or routine that can be called on an object to perform a specific task.
  • Inheritance: The ability of one class to inherit properties and methods from a parent class. This allows for code reuse and the creation of more specialized classes.
  • Interface: A set of methods that a class must implement. Interfaces are used to define a contract for a course to follow.
  • Package: A grouping of related classes and interfaces. Packages are used to organize code and prevent naming conflicts.
  • JRE (Java Runtime Environment): The software environment in which Java applications run. It includes the JVM and a set of libraries, and other files.
  • JDK (Java Development Kit): A set of tools for developing Java applications, including the JRE, a compiler, and other tools.
  • JIT (Just-In-Time) Compiler: A feature of the JVM that compiles Java bytecode into machine code at runtime. This improves the performance of Java applications.
  • Garbage Collection: A feature of the JVM that automatically frees up memory that is no longer being used by a program. This helps prevent memory leaks and other memory-related issues.

what is Angular Architecture ?

 Angular is a popular open-source web application framework maintained by Google. It provides a structured architecture for building dynamic, single-page web applications. Angular's architecture is designed to encourage best practices, modularity, and maintainability in web development. The key architectural components of an Angular application include: 1. Modules:    - Angular applications are organized into modules, which are a way to group related components, services, and other code into cohesive units. Modules help with encapsulation and code organization. 2. Components:    - Components are the building blocks of an Angular application. They represent the UI elements of the application and encapsulate the logic and templates for rendering views. Each component typically has a TypeScript class file and an HTML template. 3. Templates:    - Angular templates are used to define the structure and layout of a component's view. Templates are typically wr...
