package.json is a file used in Node.js projects to manage dependencies, scripts, and metadata.
It is a JSON file that contains information about the project, such as name, version, dependencies, and scripts.
It is used to manage project dependencies by listing them in the 'dependencies' and 'devDependencies' fields.
It allows developers to define scripts for tasks like building, testing, and running the project.
Example: {...

It is easy to solve the Aptitude question and some identifying outputs of program.
A class is a blueprint for creating objects in object-oriented programming.
A class defines the properties and behaviors of objects.
An object is an instance of a class.
Example: Class 'Car' can have properties like 'color' and 'model', and behaviors like 'drive' and 'stop'.
Swap two numbers without using temp variable and reverse a string without using built-in functions.
To swap two numbers without using temp variable, use bitwise XOR operation.
To reverse a string without using built-in functions, use two pointers approach.
Example for swapping numbers: a = a ^ b; b = a ^ b; a = a ^ b;
Example for reversing a string: use two pointers to swap characters from start and end of the string.
Now, I am preparing for the third round.
So, I don't know the Coding Question.
I appeared for an interview in May 2025, where I was asked the following questions.
Java is a versatile, object-oriented programming language designed for portability across platforms and ease of use.
Object-Oriented: Java uses objects to represent data and methods, promoting code reusability. Example: Classes and objects.
Platform-Independent: Java code is compiled into bytecode, which can run on any device with a Java Virtual Machine (JVM).
Rich API: Java provides a comprehensive set of libraries for t...
The JVM enables Java applications to run on any device by providing an environment for executing Java bytecode.
Platform Independence: JVM allows Java programs to run on any operating system without modification.
Bytecode Execution: It interprets or compiles Java bytecode into machine code for execution.
Memory Management: JVM handles memory allocation and garbage collection automatically.
Security: It provides a secure ex...
OOP is a programming paradigm based on objects, encapsulating data and behavior, promoting code reusability and modularity.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class based on an existing class, inheriting its properties (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to present the same inte...
Variables can be categorized based on their scope, lifetime, and data type, impacting how they are used in programming.
1. Local Variables: Defined within a function or block, e.g., 'int x = 10;' inside a function.
2. Global Variables: Accessible throughout the program, e.g., 'int count;' defined outside any function.
3. Static Variables: Retain their value between function calls, e.g., 'static int counter = 0;' in a func...
An interface defines a contract for classes, specifying methods and properties without implementing them.
An interface can contain method signatures and properties but no implementation.
Classes that implement an interface must provide concrete implementations for all its members.
Interfaces support multiple inheritance, allowing a class to implement multiple interfaces.
Example: In Java, 'Runnable' is an interface that re...

OOPs concepts in Java include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a subclass to inherit properties and methods from a superclass.
Polymorphism allows objects to take on multiple forms and behave differently based on their context.
Encapsulation hides the implementation details of an object and only exposes necessary information.
Abstraction allows for the creation of abstract class...
Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.
Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.
Inheritance allows for code reuse and extension of existing classes, reducing code duplication.
Polymorphism allows objects of different classes to be treated as if they were of the same class, simplifying code and i...
