Wipro Software Engineer Interview Questions, Process, and Tips

Polymorphism is the ability of an object to take on many forms.

• Polymorphism allows objects of different classes to be treated as if they are of the same class.

• It is achieved through method overriding and method overloading.

• Example: A parent class Animal can have child classes like Dog, Cat, and Bird. Each child class can have its own implementation of the method 'makeSound', but they can all be called using the same me...read more

Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

• It allows for code reuse and promotes code organization.

• The existing class is called the parent or superclass, and the new class is called the child or subclass.

• The child class inherits all the properties and methods of the parent class and can also add its own unique properties and metho...read more

Polymorphism allows objects of different classes to be treated as if they were of the same class.

• Polymorphism enables code reuse and flexibility in object-oriented programming.

• It allows for the creation of generic code that can work with objects of different classes.

• Examples include method overloading and overriding, and interfaces in Java.

• Polymorphism can improve code readability and maintainability.

• It is a key concep

A singleton class is a class that allows only a single instance of itself to be created.

• Singleton classes have a private constructor to restrict object creation.

• They provide a global point of access to the instance.

• Commonly used in scenarios where only one instance is needed, such as database connections or thread pools.

A class is a blueprint for creating objects, while an object is an instance of a class.

• A class defines the properties and methods that objects of that class will have.

• An object is created from a class and has its own unique set of values for the properties defined in the class.

• Multiple objects can be created from the same class.

• Classes can inherit properties and methods from other classes.

• Example: A class 'Car' can hav...read more

Constructor is a special method that is called when an object is created.

• Constructors have the same name as the class they belong to.

• They are used to initialize the object's state.

• They can take parameters to set initial values.

• If a class does not have a constructor, a default one is provided.

• Constructors can be overloaded to provide multiple ways of creating objects.

Destructor is a special member function that is called when an object is destroyed.

• It is used to release resources that were acquired by the object during its lifetime.

• It is automatically called when the object goes out of scope or is explicitly deleted.

• It has the same name as the class preceded by a tilde (~).

• Example: ~ClassName() { //destructor code }
