The document discusses polymorphism in object-oriented programming. It defines polymorphism as the ability for one form to take multiple forms. There are two main types of polymorphism: method overloading and method overriding. Method overloading involves methods with the same name but different parameters, while method overriding involves methods with the same name and parameters but different implementations in superclasses and subclasses. The document provides examples of each type and explains that polymorphism allows code reuse and flexibility through different object behaviors based on their types.
Polymorphism in java, method overloading and method overridingJavaTportal
Polymorphism come from the two Greek words ‘poly’ meaning many and ‘morphs” meaning forms. The ability to exist in different form is called polymorphism. The same variable or method can perform different tasks; the programmer has the advantage of writing flexible code.
Polymorphism in Java allows an object to take on multiple forms. There are two types of polymorphism: compile-time polymorphism (method overloading) and runtime polymorphism (method overriding). Method overloading involves methods with the same name but different parameters, while method overriding involves subclasses providing their own implementation of a superclass method. Runtime polymorphism determines which version of a method to call based on the object's actual type at runtime. Abstraction in Java allows hiding implementation details and showing only essential functionality through the use of abstract classes and methods.
The document discusses polymorphism in object-oriented programming. It defines polymorphism as the ability for objects of different classes related by inheritance to respond differently to the same function call. Polymorphism can be achieved through virtual functions and allows late/dynamic binding at runtime based on the actual object type. The document also discusses early/static binding at compile time, pure virtual functions that define abstract base classes, and concrete derived classes that implement pure virtual functions from the base class.
This document discusses polymorphism in object-oriented programming. It defines polymorphism as the ability for different classes to share a common interface and explains that it is commonly achieved through inheritance. The document then covers different types of polymorphism like static and dynamic, and mechanisms like function overloading, overriding, early and late binding, and pure virtual functions.
Polymorphism is the ability of an object to take more than one forms. It is one of the important concept of object-oriented programming language. JAVA is object-oriented programming language which support the concept of polymorphisms.
Alternatively, it is defined as the ability of a reference variable to change behavior according to what object instance it is holding.
This document defines polymorphism and describes its two types - compile-time and run-time polymorphism. Compile-time polymorphism is demonstrated through method overloading examples, while run-time polymorphism is demonstrated through method overriding examples. The key advantages of polymorphism are listed as code cleanliness, ease of implementation, alignment with real world scenarios, overloaded constructors, and reusability/extensibility.
This document discusses polymorphism in programming. It defines polymorphism as allowing one interface to have multiple implementations so that a method can do different things based on the object. There are two main types of polymorphism in Java: runtime polymorphism (using method overriding) and compile-time polymorphism (using method overloading). Polymorphism is useful because it allows programming in a general way rather than specific, lets programs process objects that share a superclass, and makes systems extensible with new classes that require minimal code changes.

This document discusses polymorphism in programming. It defines polymorphism as the ability for a message or data to be processed in multiple forms. There are two main types: static polymorphism (also called compile-time polymorphism), which uses method overloading and is resolved at compile time, and dynamic polymorphism (also called runtime polymorphism), which uses method overriding and is resolved at runtime. The document provides examples of each type, including method overloading in a calculation class and method overriding in shape and circle classes. Polymorphism in C# can be achieved through function overloading, operator overloading, dynamic binding, and using virtual functions.
Learn the various forms of polymorphism in Java with illustrative examples to explain method overloading(Compile-time polymorphism) and method overriding(Run-time polymorphism)
This document discusses polymorphism in C++. It defines static polymorphism as function overloading and overriding, where functions can have the same name but different parameters. Dynamic polymorphism uses virtual functions and runtime binding via pointers. Virtual functions allow overriding in derived classes. Pure virtual functions make a class abstract, requiring implementation in derived classes. Interface classes are like abstract classes but inheritance is not required.
Polymorphism refers to the ability of an object to take on multiple forms. In Java, polymorphism occurs when a reference variable can refer to objects of different subclasses. This allows methods to behave differently depending on the actual object being referred to. There are three main forms of polymorphism in Java: method overriding, abstract method implementation, and interface implementation. Polymorphism provides benefits like simplicity and extensibility by allowing code to interact generically with base types and subclasses without needing specific type details.
A set is an unordered collection of unique and immutable elements that can be of different types. Sets can contain elements of different types but not mutable elements like lists. We can perform operations like union, intersection, symmetric difference on sets. Sets are mutable, meaning we can add or remove elements, but cannot access elements by index since sets are unordered.
This document discusses implementation of inheritance in Java and C#. It covers key inheritance concepts like simple, multilevel, and hierarchical inheritance. It provides examples of inheritance in Java using keywords like extends, super, this. Interfaces are discussed as a way to achieve multiple inheritance in Java. The document also discusses implementation of inheritance in C# using concepts like calling base class constructors and defining virtual methods.
This document discusses exception handling in C++ and Java. It defines what exceptions are and explains that exception handling separates error handling code from normal code to make programs more readable and robust. It covers try/catch blocks, throwing and catching exceptions, and exception hierarchies. Finally, it provides an example of implementing exception handling in a C++ program to handle divide-by-zero errors.
The document discusses different types of conditional and control statements in Python including if, if-else, elif, nested if-else, while, for loops, and else with loops.
It provides the syntax and examples of each statement type. The if statement and if-else statement are used for simple decision making. The elif statement allows for chained conditional execution with more than two possibilities. Nested if-else allows if/elif/else statements within other conditionals. While and for loops are used to repeatedly execute blocks of code, with while looping until a condition is false and for looping over sequences. The else statement with loops executes code when the loop condition is false.
This document discusses Python functions. It defines a function as a block of code that performs a specific task. Functions help break programs into smaller, modular chunks. The document explains how to define functions using the def keyword, how to call functions, and how functions can take arguments. It also covers default arguments, keyword arguments, arbitrary arguments, recursion, anonymous functions, and provides examples of each.
This document discusses function overloading, inline functions, and friend functions in C++. It defines function overloading as having two or more functions with the same name but different parameters, allowing for compile-time polymorphism. Inline functions have their body inserted at call sites for faster execution. Friend functions are non-member functions that have access to private members of a class. Examples are provided to demonstrate overloaded functions, inline functions checking for prime numbers, and using a friend function to check if a number is even or odd. Important concepts and questions for discussion are also outlined.
This document discusses arrays in Java programming. It covers defining and creating single and multi-dimensional arrays, accessing array elements using indexes and loops, and performing operations like sorting and finding maximum/minimum values. Examples are provided for different array types like integer, string and character arrays, and operations like input/output, break/continue statements, and star patterns. Homework involves writing a program to produce a given output pattern.
The document summarizes a presentation on exception handling given by the group "Bug Free". It defines what exceptions are, why they occur, and the exception hierarchy. It describes checked and unchecked exceptions, and exception handling terms like try, catch, throw, and finally. It provides examples of using try-catch blocks, multiple catch statements, nested try-catch, and throwing and handling exceptions.
This document discusses different types of polymorphism including ad-hoc polymorphism, parametric polymorphism, and subtyping polymorphism. It defines each type and provides examples of their implementation in code. Ad-hoc polymorphism is achieved through function overloading by changing argument types, number, or order. Parametric polymorphism allows functions and data types to work with different types through generics. Subtyping polymorphism involves overriding methods in subclasses to modify superclass behavior at runtime.

The document discusses polymorphism and object-oriented programming concepts. It defines polymorphism as an object taking on many forms, and describes how it occurs through parent and child class relationships in Java. The key points are:
- Polymorphism allows a parent class reference to refer to a child class object.
- Static type refers to a reference variable's type, while dynamic type refers to the actual object's type. Dynamic binding means the method called is based on the object's dynamic type.
- Subclasses can override methods to achieve polymorphic behavior like with the display() method.
- Access modifiers like private, public, and protected determine method/field accessibility in subclasses.
- Final methods
This document discusses the concept of polymorphism in object-oriented programming. It defines polymorphism as the ability for objects of different types to respond to the same method call. The key aspects covered are:
- Polymorphism allows objects to take on multiple forms through dynamic binding, where the method executed is determined at runtime based on the actual object type.
- Subclasses can override methods from their parent class, so calling the same method on objects of different types may produce different results.
- Reference variables can refer to objects of their own type or subclasses, providing flexibility.
- The instanceof operator determines an object's actual type at runtime.
- Interfaces support polymorphism by allowing implementation by
Polymorphism is a feature of OOPs. Polymorphism is a feature that allows one interface to be used for a general class of actions. Polymorphism performs a single step in different ways. polymorphism Greek, meaning ―many forms.
This document discusses polymorphism in Java programs. Polymorphism refers to the ability of an object to take on multiple forms. In Java, polymorphism allows a reference variable to change behavior based on the object it is holding. There are three forms of polymorphism in Java: method overriding, overriding abstract methods of an abstract class, and implementing interface methods. Polymorphism provides benefits like simplicity and extensibility in code.
Java Polymorphism: Types And Examples (Geekster)Geekster
Polymorphism is one of the 4 pillars of Object-Oriented Programming. It is a
combination of two Greek words: poly and morphs. “Poly” means “many,” and
“morphs” means “forms.” So in Java, polymorphism means many forms.
Polymorphism is defined as the ability of a message to be displayed in more than
one form.
This document discusses polymorphism in object-oriented programming. It defines polymorphism as occurring when classes are related through inheritance and can perform the same action in different ways. There are two types of polymorphism: compile-time polymorphism, where function overloading and operator overloading are examples of static binding determined at compile-time; and runtime polymorphism, where function overriding is an example of dynamic binding determined at runtime based on the object type.
This document provides an overview of object-oriented programming concepts in Java including classes, objects, encapsulation, inheritance, polymorphism, abstraction, overriding and overloading methods, reference variable casting, constructors and instantiation. Key points covered include defining classes and objects, using access modifiers for encapsulation, inheritance relationships between classes, polymorphism through method overriding, rules for overriding methods, and how to properly create and initialize objects using constructors.
This document discusses key concepts in object-oriented programming including encapsulation, inheritance, polymorphism, and abstraction. Encapsulation involves restricting access to certain areas of a class and providing access through public methods. Inheritance allows classes to share behaviors through a parent-child relationship. Polymorphism enables one interface to have different implementations. Abstraction hides implementation details and exposes only functionality through abstract classes and interfaces.
In computer science, divide and conquer is an algorithm design paradigm. A divide-and-conquer algorithm recursively breaks down a problem into two or more sub-problems of the same or related type, unt…
So, who originally said divide and conquer? It has also led to the discovery of other useful algorithms like Karatsuba’s multiplication method, the Strassen algorithm, and rapid Fourier transforms .
techwithtech.com
Divide and conquer algorithms work well with processors because of their parallel structure. They also allow for easy storing and accessing by memory caches.
Divide and Conquer strategy uses recursion that makes it a little slower and if a little error occurs in the code the program may enter into an infinite loop.
Using Divide and Conquer, we can multiply two integers in less time complexity. We divide the given numbers in two halves. Let the given numbers be X and Y.

Learn Polymorphism in Python with Examples.pdfDatacademy.ai
In Python, polymorphisms refer to the occurrence of something in multiple forms. As part of polymorphism, a Python child class has methods with the same name as a parent class method. This is an essential part of programming. A single type of entity is used to represent a variety of types in different contexts (methods, operators, objects, etc.)

A small presentation on Polymorphism in Java that I made for college in my BSc 2nd semester.
P.S.- I am an indie developer, check out my apps and games :)
This document provides an overview of object-oriented programming concepts in Java including two programming paradigms, OOP principles like encapsulation, polymorphism, abstraction and inheritance. It discusses classes, objects, and reference variables in Java. Key points covered are how classes act as blueprints for objects, the difference between objects and reference variables, and how methods can be called on objects.
This document summarizes key concepts about polymorphism in C#, including method overloading, method overriding, and the base and sealed keywords. It explains that polymorphism allows the same method name to have different implementations. Method overloading uses the same name but different parameters at compile-time, while method overriding uses the same name and signature but different implementations at runtime through inheritance. The base keyword accesses members of the parent class, and sealed prevents a class or method from being overridden or inherited.
This document discusses polymorphism in C# through method overloading and overriding. It defines polymorphism as the ability to take multiple forms, and describes how it allows defining methods with the same name but different parameters (overloading) or same signature in a base and derived class (overriding). It provides examples of overloading methods based on number/type of arguments, and overriding a virtual method using the override keyword. The base keyword and sealed modifier are also introduced.

This document provides an overview of pointers, polymorphism, inheritance, and other object-oriented programming concepts in C++. It defines pointers and describes how they store memory addresses. It explains runtime and compile-time polymorphism using method overriding and overloading. Inheritance hierarchies like single, multiple, and multilevel inheritance are covered. Virtual functions and base classes are defined as ways to implement polymorphism. Abstract classes with pure virtual functions are introduced.
The document discusses the Abstract Factory pattern, which defines an interface for creating families of related objects without specifying their concrete classes. It provides advantages like isolating code from implementation classes and promoting consistency. The implementation overview describes creating shape and color interfaces and classes, an AbstractFactory interface, and Factory classes that extend AbstractFactory and create shape and color objects. FactoryProducer is used to get the appropriate factory. Tests create objects using the factories to demonstrate the pattern.
This document discusses the different types of joins in SQL, including inner joins, outer joins, and natural joins. Natural joins can be performed without using the JOIN keyword by listing tables separated by commas in the FROM clause and specifying the common column in the WHERE clause. There are 8 types of joins total, with inner joins being the most common way to combine row data from two tables through matching column values.
The document provides an overview of entity relationship diagrams (ERDs) including their basic components, different notations, and how to implement various relationship types in a relational database. ERDs depict entities, attributes, and relationships in a conceptual database design. Key points covered include the three main notations of ERDs, solving multi-valued attributes and many-to-many relationships, and how to implement one-to-one, one-to-many, and many-to-many relationships through primary and foreign key constraints.

Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

3. Definition
• Polymorphism is an object-oriented programming concept that refers
to the ability of a variable, function or object to take on multiple
forms. A language that features polymorphism allows developers to
program in the general rather than program in the specific.
• Following are the main types of polymorphism
1. Ad-hoc Polymorphism
2. Parametric Polymorphism
3. Subtyping Polymorphism

4. Ad-hoc Polymorphism
• It is also known as Function Overloading or Static Binding and also
Operator Overloading.
• Ad-hoc Polymorphism is a phenomenon in which you can create
multiple functions with the same name but that have different
headers or signature.
• It can be achieved using following ways
1. By changing the type of arguments
2. By changing the order of arguments
3. By changing number of arguments
• You can not change the return-type of a function in overloading.

5. Implementation (1)
by changing number of arguments
• You can change the number of arguments to overload a method.
A simple example is shown in the picture, where a
method “Add” is overloaded three times with same
return-type but with different number of arguments.
First method takes one argument, second take two and
third takes three arguments. You can call the Add method
with any number of arguments (from 1 to 3 of course)
compiler will choose a proper method on compile time.
As the compiler choses the proper method on compile
time that’s why it is called compile time polymorphism or
Static polymorphism.
Note: in example all arguments are of type integer but
you can give any type of argument and provide a proper
functionality. And same is the case with Constructors.

6. Implementation (2)
by changing type of arguments
• You can achieve this by just changing the type of arguments.

You see that, we don’t change the
number of arguments here in this
example, but we change the type
from integer to double. And by doing
this we have achieved the
polymorphism.
7. Implementation (3)
by changing order of arguments
• You can also just change the order of arguments to overload a method

Here in this example, there are two overloaded
method in the class. We overload them by just
changing the order of arguments.
In first method, integer is 1st argument and string is 2nd
argument but in the second method string is 1st
argument and integer is the 1st argument.
8. Parametric Polymorphism
• It is also known as Template Polymorphism or Late/dynamic Binding.
• Parametric polymorphism allows a function or a data type to be written
generically, so that it can handle values identically without depending on
their type. Parametric polymorphism is a way to make a language more
expressive, while still maintaining full static type-safety.
• The concept of parametric polymorphism applies to both data types and
functions. A function that can evaluate to or be applied to values of
different types is known as a polymorphic function. A data type that can
appear to be of a generalized type (e.g., a list with elements of arbitrary
type) is designated polymorphic data type like the generalized type from
which such specializations are made.

9. Implementation
22-Dec-14 Mudasir Qazi - mudasirqazi00@gmail.com 9
A generic function swap is shown in the picture.
This method can work with any type you will
provide in angle brackets even with strings and
complex types.
I have created integers and characters in this
example and same function will swap both type of
variables.
This is parametric polymorphism and swap
function is polymorphic function.
10. Subtyping Polymorphism
• It is also known as Method Overriding or Late Binding or Dynamic
Binding or Inclusion Polymorphism.
• Method Overriding is when a method defined in a superclass or
interface is re-defined by one of its subclasses, thus
modifying/replacing the behavior the superclass provides. The
decision to call an implementation or another is dynamically taken at
runtime, depending on the object the operation is called from. Notice
the signature of the method remains the same when overriding.

11. Implementation
22-Dec-14 Mudasir Qazi - mudasirqazi00@gmail.com 11
The picture shows the implementation of method overriding or
subtyping polymorphism.
Abstract class has a method that is re-defined in each concrete class
with respect to their requirements with same signature.
In the main method, when we create objects of concrete classes and
call there talk method we get different output as implemented.
letsHear(new Cat()) => Meow!
letsHear(new Dog()) => Woof!
The abstract class’s method is overridden on runtime, the compiler sees
which object is calling the method, if that method is available in same
class then it would be called, if not, then super class’s method would be
called.
12. Casting in Polymorphism (1)
• Two types of castings are done in polymorphism
1. Up Casting
2. Down Casting
• Up-casting is casting to a supertype, while Down-casting is casting to a subtype. Supercasting is always
allowed, but subcasting involves a type check and can throw a ClassCastException. A cast from from Dog to
an Animal is a upcast, because a Dog is-a Animal. In general, you can upcast whenever there is an is-a
relationship between two classes. Downcasting would be something like this:
• Animal animal = new Dog();
• Dog castedDog = (Dog) animal;
• Basically what you're doing is telling the program that you know what the runtime type of the object really
is. The program will do the conversion, but will still do a sanity check to make sure that it's possible. In this
case, the cast is possible because at runtime animal is actually a Dog even though the static type of animal is
Animal. However, if you were to do this:
• Animal animal = new Animal();
• Dog dog = (Dog) animal;
• You'd get a ClassCastException. The reason why is because animal's runtime type is Animal, and so when you
tell the runtime to perform the cast it sees that animal isn't really a Dog and so throws a ClassCastException.
To call a superclass's method you can do super.method() or be performing the upcast. To call a subclass's
method you have to do a downcast and risk the ClassCastException.
