Most asked questions in tcs interview

1) What are Basic Principles of OOP (Object-Oriented Programming)?

Answer: The basic principles of Object-Oriented Programming (OOP) are:

• Encapsulation: It is the process of hiding the implementation details of a class from other objects. Encapsulation allows for information hiding, making it easier to maintain and modify code without affecting other parts of the program.

• Inheritance: It is a mechanism that allows a class to inherit properties and behavior from another class. Inheritance provides a way to reuse code and create relationships between objects.

• Polymorphism: It is the ability of an object to take on many forms. In programming, it can be achieved through method overloading or method overriding.

• Abstraction: It is the process of simplifying complex systems by breaking them down into smaller, more manageable pieces. Abstraction allows for the creation of more modular, flexible code, making it easier to maintain and extend.

2) What is the difference between an abstract class and an interface in Java?

• Answer - An abstract class is a class that can have both abstract and non-abstract methods and can also have constructors, whereas an interface can only have abstract methods and constants, and no constructors. In Java, a class can implement multiple interfaces but can only extend one abstract class

3) What is the difference between stack and queue data structures?

• Answer - A stack is a data structure in which insertion and deletion of elements take place from the top of the stack. On the other hand, a queue is a data structure in which insertion takes place at the rear end and deletion of elements take place from the front end.

4) Explain the concept of polymorphism in object-oriented programming.

• Answer - Polymorphism is the ability of an object to take on multiple forms. It allows objects of different classes to be treated as if they were objects of a common superclass

5) What are the different types of testing methodologies used in software development?

• Answer - Different types of testing methodologies used in software development include Unit Testing, Integration Testing, System Testing, Acceptance Testing, Regression Testing, and Performance Testing.

6) Explain the process of software development life cycle.

• Answer - The software development life cycle (SDLC) is the process of planning, designing, building, testing, deploying, and maintaining software applications. It is a framework that provides a structured approach to develop high-quality software products.

7) What is a database? Explain the different types of databases.

Answer - 

• A database is a collection of data that is organized and stored in a way that enables efficient retrieval and manipulation of data.

• There are different types of databases such as relational databases, NoSQL databases, object-oriented databases, graph databases, etc. which differ in their structure, data storage and retrieval methods, and the types of queries they support.

8) Explain the importance of version control systems like Git in software development.

• Answer - Version control systems like Git are important in software development as they allow developers to manage and track changes to code over time, collaborate with other developers, and revert to previous versions of code if needed

9) What is an API? How is it used in software development?

• Answer - API stands for Application Programming Interface. It is a set of protocols, routines, and tools for building software and applications. APIs are used to connect different software components and enable communication between them, allowing developers to create new applications by leveraging existing functionalities

10) Explain the concept of recursion and provide an example.

• Answer - Recursion is a technique in programming where a function calls itself to solve a problem. An example of recursion is the Fibonacci sequence

11) What is the difference between a local and global variable in programming?

• Answer - A local variable is declared inside a function or a block and can only be accessed within that function or block. A global variable, on the other hand, is declared outside of any function and can be accessed by any function in the program.
