Java testing involves various methodologies to ensure code quality, functionality, and performance through systematic testing processes.
Unit Testing: Testing individual components (e.g., JUnit for testing methods in isolation).
Integration Testing: Ensuring different modules work together (e.g., using TestNG for testing interactions).
Functional Testing: Validating the software against functional requirements (e.g.,...
A copy constructor is a special type of constructor in object-oriented programming that creates a new object as a copy of an existing object.
Copy constructor is used to initialize a new object as a copy of an existing object.
It takes an object of the same class as a parameter.
It is typically used to create deep copies of objects to avoid shallow copy issues.
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.
Encapsulation helps in hiding the internal state of an object and restricting access to it.
It allows for better control over the data by preventing outside interference.
Encapsulation also helps in achieving data abstraction and information hiding.
Example: In object-oriented programming, a class encapsulates data (...

What people are saying about Virtusa Consulting Services
Object class is the root class for all Java classes, providing common methods and behaviors for all objects.
Object class is at the top of the class hierarchy in Java
All classes in Java are directly or indirectly derived from the Object class
Object class provides methods like equals(), hashCode(), toString() which can be overridden in subclasses
Use a loop to swap characters of two strings without using strcpy function.
Create two arrays of characters to store the strings
Use a loop to iterate through each character of the strings and swap them
Ensure to handle cases where strings have different lengths
Run time polymorphism allows methods to be overridden in derived classes, enabling dynamic method resolution.
Achieved through method overriding in inheritance.
Example: A base class 'Animal' with a method 'sound()' overridden in 'Dog' and 'Cat'.
The method called is determined at runtime based on the object type.
Supports flexibility and scalability in code design.
A linked list is a linear data structure where elements are stored in nodes, each pointing to the next node.
A linked list consists of nodes, each containing data and a reference to the next node.
Types of linked lists include singly linked lists, doubly linked lists, and circular linked lists.
Example of a singly linked list: Node1 -> Node2 -> Node3 -> NULL.
Doubly linked list allows traversal in both direct...
Polymorphism allows objects to be treated as instances of their parent class, enhancing flexibility and code reusability.
Polymorphism can be achieved through method overriding and method overloading.
Example of method overriding: A base class 'Animal' has a method 'makeSound()', and subclasses 'Dog' and 'Cat' implement their own versions.
Method overloading allows multiple methods with the same name but different pa...
Deep copy creates a new copy of an object with its own unique memory space, while shallow copy creates a new object that references the same memory locations as the original object.
Deep copy duplicates all nested objects, while shallow copy only duplicates the references to nested objects.
Deep copy ensures that changes to the copied object do not affect the original object, while shallow copy may lead to unintende...

- Q1. What is Oops with examples
- Ans.
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.
OOP focuses on creating objects that interact with each other to solve problems
