10+ Assumere Consultants Interview Questions and Answers

Overloading is when multiple methods have the same name but different parameters, while overriding is when a subclass provides a specific implementation of a method already defined in its superclass.

• Overloading is compile-time polymorphism, while overriding is runtime polymorphism.

• Overloading is achieved within the same class, while overriding occurs between a superclass and its subclass.

• Overloading is used to provide different ways of calling the same method, while overridin...read more

Local variables are variables declared within a function or block. Global variables are declared outside of any function or block.

• Local variables have a limited scope and can only be accessed within the function or block they are declared in.

• Global variables can be accessed from any part of the program.

• Arrays are a collection of similar data types stored in contiguous memory locations.

• Pointers are variables that store the memory address of another variable.

OOPs is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPs stands for Object-Oriented Programming.

• It focuses on creating objects that interact with each other to solve a problem.

• It has four main concepts: encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation is the process of hiding data and methods within an object.

• Inheritance allows a new class to be based on an existing class, inheriting its properties and methods...read more

OOPS stands for Object-Oriented Programming System in Java. Palindrome number is a number that remains the same when its digits are reversed.

• OOPS is a programming paradigm that focuses on objects and their interactions.

• Java is an object-oriented programming language that supports OOPS concepts.

• Palindrome number examples: 121, 1221, 12321, etc.

• To check if a number is palindrome, reverse the number and compare it with the original number.

Operator overloading is the ability to redefine operators for user-defined types. Operator overriding is redefining inherited operators.

• Operator overloading allows operators to be used with user-defined types, such as adding two objects together.

• Overriding allows a subclass to provide a different implementation of a method that is already defined in its superclass.

• Examples of overloaded operators include +, -, *, /, and =.

• Examples of overridden methods include toString(), equ...read more

Oops stands for Object-Oriented Programming System. It is a programming paradigm based on the concept of objects.

• Oops is based on the concept of classes and objects.

• It allows for encapsulation, inheritance, and polymorphism.

• Objects can have attributes (data) and methods (functions).

• Example: In a car class, attributes could be color and model, and methods could be start() and stop().

Java is a popular programming language known for its platform independence and object-oriented features.

• Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM)

• It is object-oriented, allowing for modular and reusable code

• Java is known for its robust standard library, providing a wide range of pre-built functionality

• It supports multithreading, allowing for concurrent execution of tasks

• Java is statically typed, catching errors at compile ...read more

Use the ORDER BY clause with DESC and LIMIT to find the second largest number in SQL.

• Use the ORDER BY clause to sort the numbers in descending order.

• Use the LIMIT clause to limit the result to the second row.

• Example: SELECT column_name FROM table_name ORDER BY column_name DESC LIMIT 1, 1;

Program to reverse a number

• Use modulus operator to extract the last digit of the number

• Multiply the reversed number by 10 and add the extracted digit

• Repeat until all digits are processed

Java is a high-level programming language known for its platform independence due to its ability to run on any device with a Java Virtual Machine (JVM).

• Java is a class-based, object-oriented language used for developing applications and software.

• It is compiled into bytecode that can run on any device with a JVM, making it platform independent.

• Java programs are written once and can run on any platform without the need for recompilation.

• Examples of platform independent Java app...read more

Pointer to pointer is a variable that stores the address of another pointer variable.

• It is used to allocate memory dynamically.

• It is used in multi-level pointer referencing.

• It is denoted by ** in C/C++.

• Example: int **ptr;

• Example: char **names;

A loop in C++ is a programming structure that repeats a set of instructions until a specific condition is met.

• There are three types of loops in C++: for, while, and do-while.

• For loop is used when the number of iterations is known beforehand.

• While loop is used when the number of iterations is not known beforehand.

• Do-while loop is similar to while loop, but it executes the code block at least once before checking the condition.

• Loops can be nested within each other to create com...read more

C is a low-level programming language while Python is a high-level programming language.

• C is compiled while Python is interpreted

• C is faster and more memory-efficient than Python

• Python has simpler syntax and is easier to learn than C

• C is used for system programming, embedded systems, and game development while Python is used for web development, data analysis, and artificial intelligence

• C requires manual memory management while Python has automatic memory management

Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, preventing direct access to the data from outside the unit.

• Encapsulation helps in data hiding and abstraction

• It allows for better control over data by restricting access to certain components

• Example: In object-oriented programming, classes encapsulate data and methods to create objects

An array is a data structure that stores a collection of elements of the same type in a contiguous memory location.

• Declare an array by specifying the data type of the elements and the size of the array.

• Initialize the array by assigning values to each element.

• Access elements in the array using their index, starting from 0.

• Example: String[] names = new String[3]; names[0] = "Alice"; names[1] = "Bob"; names[2] = "Charlie";

Call by value is a method of passing arguments to a function where the actual value of the argument is copied to the formal parameter of the function.

• The value of the actual parameter is copied to the formal parameter of the function

• Changes made to the formal parameter inside the function do not affect the actual parameter

• Primitive data types like int, float, char are passed by value

OOPs stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.

• OOPs focuses on creating objects that contain data and methods to manipulate that data.

• Encapsulation, inheritance, and polymorphism are key principles of OOPs.

• Examples of OOPs languages include Java, C++, and Python.

Inheritance is a concept in object-oriented programming where a class can inherit attributes and methods from another class.

• Inheritance allows for code reusability and promotes the concept of hierarchy in programming.

• A subclass can inherit attributes and methods from a superclass, but can also have its own unique attributes and methods.

• For example, a 'Vehicle' class can be a superclass, with subclasses like 'Car' and 'Truck' inheriting attributes like 'color' and methods like...read more
