  1.1 What is Artificial Intelligence? Definition : Artificial Intelligence (AI) is the branch of computer science that aims to create machines that can mimic human intelligence and behavior. Popular Definitions : "AI is the science and engineering of making intelligent machines." – John McCarthy (Father of AI) "AI is the study of how to make computers do things which, at the moment, people do better." – Elaine Rich 1.2 Goals of Artificial Intelligence (AI) The main goal of AI is to create machines that can think and act like humans. These systems are designed to perform tasks that usually require human intelligence. The key goals include: Thinking and Reasoning: AI should be able to solve problems and make decisions by thinking logically, just like a person would. Learning from Experience: AI systems should improve over time by learning from data and past experiences, similar to how humans learn. ...

OBJECT ORIENTED PROGRAMMING THROUGH JAVA : Unit - 3 : Topic - 1 : Arrays

-
Image
1. Introduction to Arrays Definition An array in Java is a collection of variables of the same data type stored at contiguous memory locations . It allows us to store multiple values in a single variable, instead of declaring separate variables for each value. Arrays are fixed-size (the size must be defined at the time of creation). Each element in an array is accessed using an index . Array indexing in Java starts from 0 . Why Arrays? To handle large amounts of data efficiently. Easy traversal using loops. Better performance as elements are stored in continuous memory. Key features of Arrays Store Primitives and Objects: Java arrays can hold both primitive types (like int, char, boolean, etc.) and objects (like String, Integer, etc.) Contiguous Memory Allocation When we use arrays of primitive types, the elements are stored in contiguous locations. For non primitive types, references of items are stored at contiguous locations. Zero-based Indexing: The first e...
