As the name suggests, Object-Oriented Programming or OOPs refers to languages that uses objects in programming. Object-oriented programming aims to implement real-world entities like inheritance, hiding, polymorphism etc in programming. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.
The document provides an overview of core Java concepts including:
- Java is an object-oriented programming language and platform that runs on a virtual machine. It is used to create desktop, web, enterprise, mobile and other applications.
- Core Java concepts include objects, classes, inheritance, polymorphism, abstraction and encapsulation. The document also discusses variables and data types, OOP principles, object creation, method overloading and constructors.
- It provides examples of Hello World programs and explains Java memory areas like stack and heap. Key topics like static keyword, method vs constructor and method overloading are also summarized.
The document discusses multithreading in Java. It defines a thread as the smallest unit of processing and describes how Java allows executing multiple threads simultaneously. It outlines the five states in a thread's lifecycle and how threads transition between these states. It also discusses how to create threads by extending the Thread class or implementing the Runnable interface. Additionally, it covers common thread methods like sleep(), join(), getName(), currentThread(), and setting priority. The document concludes with a brief overview of synchronization in Java.
- Java uses streams to perform input and output operations which allow for fast processing. Streams are sequences of data composed of bytes.

Exception handling in Java allows programs to gracefully deal with errors and unexpected conditions. There are two types of exceptions: checked exceptions which must be explicitly caught, and unchecked exceptions which do not need to be caught. The try-catch block is used to catch exceptions, where code that might throw an exception is placed in the try block and catch blocks handle specific exceptions. Finally blocks are always executed and can be used to perform cleanup tasks. Exceptions can also be explicitly thrown using the throw keyword or declared as thrown from methods using the throws clause.

HISTORY OF NEWSPAPER:
1. Acta Diurna, the First Newspaper to be published:-
Talking about the first newspaper to be published ever, it was Acta Diurna that was published in Rome that has been a place known for the political power in the olden periods of history. The date of its publication was around 59 B.C and it was basically implemented for the purpose of political affairs.
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.
Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.
The dominant general-purpose[3] personal computer operating system is Microsoft Windows with a market share of around 76.45%. macOS by Apple Inc. is in second place (17.72%), and the varieties of Linux are collectively in third place (1.73%).[4] In the mobile sector (including smartphones and tablets), Android's share is up to 72% in the year 2020.[5] According to third quarter 2016 data, Android's share on smartphones is dominant with 87.5 percent with also a growth rate of 10.3 percent per year, followed by Apple's iOS with 12.1 percent with per year decrease in market share of 5.2 percent, while other operating systems amount to just 0.3 percent.[6] Linux distributions are dominant in the server and supercomputing sectors. Other specialized classes of operating systems (special-purpose operating systems),[3][7] such as embedded and real-time systems, exist for many applications. Security-focused operating systems also exist. Some operating systems have low system requirements (e.g. light-weight Linux distribution). Others may have higher system requirements.
This document discusses Java applets, including their lifecycle and methods. Applets are small Java programs that can be downloaded and run in a web browser. They have a lifecycle involving initialization, running, idle, and destruction states. Key methods like init(), start(), stop(), and destroy() move the applet between these states. The document also covers creating basic applets, using graphics, images, audio, and threads in applets.
What is Java?
Java is a popular programming language, created in 1995.
It is owned by Oracle, and more than 3 billion devices run Java.
It is used for:
Mobile applications (specially Android apps)
Desktop applications
Web applications
Web servers and application servers
Games
Database connection
And much, much more!
Why Use Java?
Java works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.)
It is one of the most popular programming language in the world
It is easy to learn and simple to use
It is open-source and free
It is secure, fast and powerful
It has a huge community support (tens of millions of developers)
Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs
As Java is close to C++ and C#, it makes it easy for programmers to switch to Java or vice versa
Neurons are the building blocks of the nervous system. They receive and transmit signals to different parts of the body. This is carried out in both physical and electrical forms. There are several different types of neurons that facilitate the transmission of information.
The sensory neurons carry information from the sensory receptor cells present throughout the body to the brain. Whereas, the motor neurons transmit information from the brain to the muscles. The interneurons transmit information between different neurons in the body.
The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems.HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser.
Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP protocol version that was named 0.9.
That first version of HTTP protocol soon evolved into a more elaborated version that was the first draft toward a far future version 1.0.
Development of early HTTP Requests for Comments (RFCs) started a few years later and it was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to the IETF.
HTTP/1 was finalized and fully documented (as version 1.0) in 1996.[4] It evolved (as version 1.1) in 1997 and then its specifications were updated in 1999 and in 2014.
Its secure variant named HTTPS is used by more than 76% of websites.
HTTP/2 is a more efficient expression of HTTP's semantics "on the wire", and was published in 2015; it is used by more than 45% of websites;it is now supported by almost all web browsers (96% of users) and major web servers over Transport Layer Security (TLS) using an Application-Layer Protocol Negotiation (ALPN) extension[9] where TLS 1.2 or newer is required.
Presenting information clearly and effectively is a key skill in getting your message across. Today, presentation skills are required in almost every field, and most of us are required to give presentations on occasions. While some people take this in their stride, others find it much more challenging.
It is, however, possible to improve your presentation skills with a bit of work.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
