Derived class
visibility modes
Types of inheritance
Virtual base class
Constructors in derived classes
Inheritance
The mechanism of deriving a new class from an old class is called inheritance.
The old class is referred as base class and new one is called as derived class.
A new class inherits some or all properties from the base class.
Inheritance enables reusability.
This presentation will helpful for Android Beginner's to refresh the OOPS Concepts which is very basic things for Android Mobile Application Development.

oops concept in java | object oriented programming in javaCPD INDIA
object oriented programming is a key concept for the development of application in windows as well as web based application environment. oops concept maps real world through its concept of classes, objects, inheritance, polymorphism which help in making a robust application.
Introduction to OOPS, Characteristics of OOPS, Object oriented languages, comparison between
procedural and object oriented programming, basic principles of Object Orientation-class, object,
abstraction, encapsulation, inheritance, polymorphism, modularity, and message passing. Features
of object orientation - attributes, state, identity, operation, behaviour.
Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Top 10 Java Oops Interview Questions
http://crbtech.in/Student-Review
1.What exactly is the Java’s oops concept?
Oops is a methodology that gives a way for modularizing a program by developing a partitioned memory location
for both data and its methods that can be utilized as format for creating duplicates of such modules on interest.
The four types include:
Inheritance
Polymorphism
Encapsulation
Abstraction
3. Top 10 Java Oops Interview Questions

2. What do you mean by encapsulation?
The process of associating data with related methods is called encapsulation. Class forms the core of this.
3. Define a class:
In case of oops, a class is a collection of variable/s and method/s for a particular type of object. An object is considered to be an instance of
a class. It happens to be a user defined data type in Java.
4. What do you mean by an object?
It forms an instance of a class. Object can be defined as any entity that has attributes, methods associated with it. An object is used to
allocate dynamic memory to a class.
5. State the object characteristics
The three characteristics of an object are:
Identity
Behavior
State
6. Explain inheritance
Self explanatory, it means to intake what already exists.
One of the most important concepts. The purpose is purely re-usability.
Used for inheriting properties from one class object to another one.
In simple terms, just like you inherit qualities from your parents!

7. How is inheritance put to use in Java?
Inheritance is used in Java with the help of two keywords namely ‘extends’ and
‘implements’.
With the help of ‘extends’, inheritance between two interfaces or classes can be
established. While,
‘implements’ is used to establish inheritance amongst interface and class.
e.g.
package com.instanceofjava;
class A{ }
package com.instanceofjava;
class B extends A{ }

8. State the different types of inheritances
Inheritance is divided into two main types namely-
Multiple inheritance
Multilevel inheritance
Multiple inheritance:
The funda of getting objects from multiple classes into single class object is called multiple inheritance. It is
not supported in Java programming.
Multilevel inheritance:
Getting properties from object of one class to another class object, is called multilevel inheritance.
e.g. package com.instanceofjava;
class A{ }
class B extends A{}
class C extends B{}

9. Define polymorphism
Using same names for more than one method.
One of the most popular java interview questions.
Two types are:
Static polymorphism and Dynamic polymorphism
Static:
Also called as method overloading
Multiple methods with same name and different parameters.
Dynamic:
Defining more than one methods with identical signature in sub class and super class.
The always executed method in this case will be sub most object.
7. Top 10 Java Oops Interview Questions

10. Elaborate this and super keywords
Super:
A keyword used to store super class non -static members reference in sub class object.
Used to differentiate between sub class and super class members if the names are same.
System.out.println(super); would give compilation Error.
This:
Current object reference is stored in this.
Should be used when non-static variable and local variables’ name happens to be one.
System.out.print(this); would work fine.
So, these were some of the popular oops concepts and the very basic ones that form Java core interview questions.
There are many institutes present for Java training Pune. You can benefit by joining them.
