Artificial Intelligence (AI) Machine Learning (ML) Deep Learning

Artificial Intelligence (AI) Artificial Intelligence ( AI ) is the field of computer science focused on creating systems that can perform tasks typically requiring human intelligence.  These tasks include learning, reasoning, problem-solving, perception, and language understanding. Core Concepts : Machine Learning (ML): Algorithms that allow computers to learn from data and improve over time without being explicitly programmed. Natural Language Processing ( NLP ): Enables machines to understand, interpret, and respond to human language (like what we're doing right now!). Computer Vision : Allows machines to interpret and make decisions based on visual data (e.g., recognizing faces or objects). Robotics: Combines AI with mechanical systems to create intelligent machines that can interact with the physical world. Expert Systems : AI programs that mimic decision-making abilities of human experts in specific domains. Types : Narrow AI | Specialized in one task (e.g., voice assista...

Java Data Types

Q. Explain different data types in Java. There are 2 types of data types in Java as mentioned below:   1. Primitive Data Type   2. Non-Primitive Data Type or Object Data type Primitive Data Type : Primitive data are single values with no special capabilities. There are 8 primitive data types:   - boolean: stores value true or false   - byte: stores an 8-bit signed two's complement integer   - char: stores a single 16-bit Unicode character   - short: stores a 16-bit signed two’s complement integer   - int: stores a 32-bit signed two’s complement integer   - long: stores a 64-bit two’s complement integer   - float: stores a single-precision 32-bit IEEE 754 floating-point   - double: stores a double-precision 64-bit IEEE 754 floating-point The default value of the byte datatype in Java is 0. The default value of the float is 0.0f and of double is 0.0d in Java. Non-Primitive Data Type : Reference Data types will contain a memory address of t...

Java OOPs

Q. What is an object-oriented paradigm? Paradigm literally means a pattern or a method.  Programming paradigms are the methods to solve a program that is of four types namely, Imperative, logical, functional, and object-oriented.  When objects are used as base entities upon which the methods are applied, encapsulation or inheritance functionalities are performed, it is known as an object-oriented paradigm. Q. What is the difference between an object-oriented programming language and an object-based programming language? Object-oriented programming language covers larger concepts like inheritance, polymorphism, abstraction, etc. It supports all the built-in objects   Ex: Java, C#, etc. The scope of object-based programming is limited to the usage of objects and encapsulation. It doesn’t support all the built-in objects   Ex: JavaScript, Visual Basics, etc. Q. What are the main concepts of OOPs in Java? The main concepts of OOPs in Java are mentioned below:   Inhe...

Java Class and Object

  Q. What are Classes in Java?  In Java, Classes are the collection of objects sharing similar characteristics and attributes.  Classes represent the blueprint or template from which objects are created.  Classes are not real-world entities but help us to create objects which are real-world entities.  Q. What is an object? The object is a real-life entity that has certain properties and methods associated with it.  The object is also defined as the instance of a class.  An object can be declared using a new keyword. Q. What are the different ways to create objects in Java? Methods to create objects in Java are mentioned below: Using new keyword Using new instance Using clone() method Using deserialization Using the newInstance() method of the Constructor class Q. What will be the initial value of an object reference which is defined as an instance variable? The initial value of an object reference which is defined as an instance variable is a NULL valu...

Q. What is Java? Java is a programming language and a platform. Platform: Any hardware or software environment in which a program runs, is known as a platform.  Since Java has a runtime environment (JRE) and API, it is called a Platform. Java is a high level, robust, object-oriented and secure programming language. Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995 Java was developed by James Gosling, who is known as the father of Java, in 1995. Q: What are the top Java Features? Simple : Java is quite simple to understand and the syntax Platform Independent : Java is platform independent means we can run the same program in any software and hardware and will get the same result. Interpreted : Java is interpreted as well as a compiler-based language.  Robust : features like Garbage collection, exception handling, etc that make the language robust. Object-Oriented : Java is an object-oriented language that supports the concepts of cl...

DevOps, Cloud, SRE, and Platform Engineering

Q: What is difference between DevOps, Cloud, SRE, and Platform DevOps, cloud, SRE (Site Reliability Engineering), and platform engineering are related but distinct concepts in modern software development and IT operations. DevOps focuses on cultural and process changes to streamline software development and deployment. Cloud refers to on-demand access to computing resources, often via a third-party provider. SRE applies engineering principles to ensure system reliability and performance. Platform engineering focuses on building and maintaining self-service platforms for developers. DevOps : DevOps is a cultural and methodological approach that emphasizes collaboration and communication between development and operations teams. It aims to automate and streamline the entire software development lifecycle, from coding and testing to deployment and monitoring, to deliver software faster and more reliably. Key principles include continuous integration, continuous delivery, and automation....
