OOP, or Object-Oriented Programming, is a programming paradigm based on the concept of objects that contain data and methods.
Encapsulation: Bundling data and methods that operate on the data within one unit, e.g., a class in Java.
Inheritance: Mechanism to create a new class using properties of an existing class, e.g., a 'Dog' class inheriting from an 'Animal' class.
Polymorphism: Ability to present the same interfa...
Python offers simplicity, readability, and a rich ecosystem, making it a preferred choice for many developers over Java.
Simplicity: Python's syntax is clean and easy to understand, reducing the learning curve for new developers.
Rapid Development: Python allows for faster prototyping and development due to its dynamic typing and extensive libraries.
Versatility: Python is used in various domains like web development...
I like Python the most.
Python is a versatile and easy-to-learn language.
It has a simple syntax and emphasizes readability.
Python has a vast ecosystem of libraries and frameworks.
It is widely used in various domains like web development, data analysis, and artificial intelligence.
Python's popularity is due to its flexibility and community support.
Object-Oriented Programming (OOP) is a paradigm based on objects, encapsulating data and behavior for better code organization.
Encapsulation: Bundling data and methods. Example: A class 'Car' with properties like 'color' and methods like 'drive()'.
Inheritance: Deriving new classes from existing ones. Example: 'ElectricCar' inherits from 'Car', adding features like 'charge()'.
Polymorphism: Methods can take many for...
What people are saying about TCS
Methods in Java are blocks of code that perform specific tasks and can be called by other parts of the program.
Methods are declared using the 'public' keyword followed by the return type, name, and parameters.
They can be called by other parts of the program using the method name and passing in any required arguments.
Methods can have a return type or be void (no return value).
They can also have access modifiers suc...
An array is a collection of elements of the same data type, stored in contiguous memory locations.
Arrays can be of any data type, including integers, floats, and objects.
Elements in an array are accessed using an index, starting from 0.
Arrays have a fixed size, which is determined at the time of declaration.
Arrays can be initialized with values at the time of declaration, or later using a loop or individual assign...
Swapping of two numbers program
Declare two variables to store the numbers
Assign values to the variables
Print the values before swapping
Swap the values using a temporary variable
Print the values after swapping
Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Bubble sort is not efficient for large data sets
It has a time complexity of O(n^2)
It works by repeatedly swapping adjacent elements if they are in the wrong order
Example: ['apple', 'banana', 'cherry', 'date'] can be sorted using bubble sort as follows: ['apple',...
SQL is a programming language used to manage and manipulate relational databases.
SQL stands for Structured Query Language.
It is used to create, modify, and query databases.
SQL is used in various applications such as web development, data analysis, and business intelligence.
Examples of SQL-based databases include MySQL, Oracle, and Microsoft SQL Server.
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
Normalization involves breaking down a database into smaller, more manageable tables.
Each table should have a primary key and only contain data that is related to that key.
Normalization helps to prevent data inconsistencies and anomalies.
There are different levels of normalization, with each level building...
