Slick is a modern database query and access library for Scala. It allows you to work with stored data almost as if you were using Scala collections while at the same time giving you full control over when a database access happens and which data is transferred. You can write your database queries in Scala instead of SQL, thus profiting from the static checking, compile-time safety and compositionality of Scala. Slick features an extensible query compiler which can generate code for different backends.

OBJECTS IN Object Oriented Programming .pptSaadAsim11
An object is an instance of a class that has an identity, state, and behavior. The identity is defined by the object's name, state represents the data values of its attributes, and behavior is represented by the functions defined in its class. Objects can be created by declaring a variable of a class type, which allocates memory for the object. Objects can be passed as arguments to functions by value, making a copy, or by reference, where changes made inside the function affect the actual object. A method can return an object as the return value.
This lab report discusses object-oriented programming concepts like classes, objects, inheritance, and constructors in Java. It includes:
1) A class defines common properties and behaviors for a group of objects, while an object is an instance of a class. A house is an object with state like address and behavior like opening doors.
2) A constructor initializes an object when it is created and can be overloaded with different parameters. Getter and setter methods are used to access private variables.
3) Inheritance allows a subclass to inherit properties and behaviors from a parent class in a hierarchical relationship. This lab report provides examples of single, multilevel, and hierarchical inheritance in Java code.
In this session, you will learn:
1. Deep dive into coding OOP with Java… with practical examples.
2. How to create a class
3. How to create objects

Kotlin for Android Developers - Victor Kropp - Codemotion Rome 2018Codemotion
Kotlin is a programming language developed by JetBrains that targets multiple platforms including the JVM, JavaScript, and native binaries. A year ago it has been adopted as an officially supported language for Android development. Kotlin offers clean and concise syntax, interoperability, both object-oriented and functional code constructs, and a lot of other cool features with little or no overhead. Let's find out together why developers love this language and how it helps them to be productive and have fun!
Here are the steps to move the frontend out of the Main class and into its own thread:
1. Create a Frontend class that extends AbstractHandler and implements Runnable
2. Move the frontend handling logic from Main into the run() method of Frontend
3. Add a handleCount field to Frontend of type AtomicInteger
4. In the run() method, periodically log the value of handleCount every 5 seconds
5. In the handle() method, increment handleCount using getAndIncrement() after generating the page
6. From Main, instantiate a Frontend object and call start() on its thread to run asynchronously
This will separate the frontend into its own thread of execution. The handleCount field
This document discusses inheritance in C++. It covers base and derived classes, single inheritance, declaring derived classes, the order of constructor and destructor execution, inherited member accessibility, and multiple inheritance. Examples are provided to illustrate single, private, protected, and public inheritance. Constructor initializers are also discussed, explaining that they are used to transfer parameters to base class constructors, rather than relying on default base class constructors followed by access functions.

This document discusses several items from Effective Java (2nd Edition) by Joshua Bloch related to Java programming best practices. It provides code examples for using static factory methods instead of constructors, using builders for classes with many constructor parameters, preferring primitive types over boxed primitives, and other topics. The examples demonstrate proper and improper usage and the benefits of following best practices related to object creation, collections, and performance.
The document is about using ImageIcon, JPanel, and Timer classes in Java.
It contains 3 sections:
1) Using ImageIcon and JPanel composition to display different images by clicking buttons.
2) Using inheritance with JPanel and Timer to create an animation class that displays a sequence of images.
3) Using Timer and JPanel to create a clock class that displays the time and updates every second.
The document provides instructions for creating a basic calculator application using Java applets and GUI components. It describes how to:
1. Create a ConApplet class that extends JApplet.
2. Add a JLabel, JTextField, and four JButtons (for numbers 1 and 2, plus sign, equals sign) to the applet's content pane.
3. Make the number buttons update the JTextField by concatenating the number to the existing text when clicked.
4. Declare three private int variables (num1, num2, ans) to store the calculation values.
The document guides the reader through setting up the basic GUI elements and behaviors for a simple two-number
PuTTY is an open source SSH and telnet client originally developed by Simon Tatham for Windows. The document provides instructions for basic telnet configuration in PuTTY, including entering an IP address and port, naming the session, setting the session to remain active for 100 seconds, changing the appearance, and saving and opening the connection.
How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
