Newgen Software Technologies Team Lead Interview Questions, Process, and Tips

Oops concept and DBMS are both important in software development, with Oops focusing on object-oriented programming and DBMS on managing databases.

• Oops concept involves classes, objects, inheritance, polymorphism, and encapsulation.

• DBMS involves creating, managing, and querying databases using SQL.

• Oops helps in organizing code and promoting reusability, while DBMS ensures data integrity and security.

• Example: In a banki...read more

Oops concept is a programming paradigm that focuses on objects and classes, promoting code reusability and modularity.

• Encapsulation: bundling data and methods that operate on the data within a single unit

• Inheritance: allows a class to inherit properties and behavior from another class

• Polymorphism: ability for objects to be treated as instances of their parent class

• Abstraction: hiding the complex implementation details

Remove duplicates from an array of strings

• Create a new set to store unique values

• Iterate through the array and add each element to the set

• Convert the set back to an array to remove duplicates
