Aisle Interview Questions and Answers

Black box testing is used to test the functionality of a software application without knowing its internal structure.

• Black box testing focuses on the external behavior of the software.

• It tests the software from a user's perspective, without any knowledge of the internal code.

• It helps identify defects or issues in the software's functionality.

• Black box testing is useful for validating requirements and ensuring the software meets user expectations.

• Examples of black box testing ...read more

Program to generate Fibonacci series

• Use a loop to generate the series

• Start with two initial values, 0 and 1

• Add the previous two numbers to get the next number

• Repeat the process until the desired number of terms is reached

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as objects of a common superclass.

• Polymorphism is achieved through method overriding and method overloading.

• Method overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass.

• Method overloading allows multiple methods with the same name but different parameters in the same class.

• Polymorphism helps in a...read more

OOPS concepts are fundamental principles in object-oriented programming.

• Encapsulation: bundling of data and methods into a single unit (class)

• Inheritance: ability of a class to inherit properties and methods from another class

• Polymorphism: ability to use a single interface to represent different types of objects

• Abstraction: hiding unnecessary details and exposing only essential features

• Encapsulation: binding data and methods together to prevent direct access and modification

A program demonstrating inheritance in object-oriented programming.

• Inheritance allows a class to inherit properties and methods from another class.

• The derived class can add new features or override existing ones.

• Inheritance promotes code reusability and modularity.

• Example: Creating a base class 'Animal' and derived classes 'Dog' and 'Cat'.

Types of testing include unit testing, integration testing, system testing, and acceptance testing.

• Unit testing focuses on testing individual components or units of code.

• Integration testing verifies the interaction between different components or modules.

• System testing ensures that the entire system functions correctly.

• Acceptance testing is performed to validate if the system meets the requirements and is ready for deployment.
