It is easy to solve the Aptitude question and some identifying outputs of program.

Q1. What is class?and write a logic for object in a class.
Ans. 
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'.

Q2. 1.swap two numbers without using temp variable 2.Reverse the string.
Ans. 
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.

Q1. What is Java?
Ans. 
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...read more

Q2. What is the purpose of the Java Virtual Machine (JVM)?
Ans. 
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...read more

Q3. What are the key concepts of Object-Oriented Programming (OOP)?
Ans. 
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...read more

Q4. What are the different types of variables?
Ans. 
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...read more

Q5. What is an interface?
Ans. 
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...read more

Q1. Write a function to find the first non-repeating character in a string ?
Ans. 
Function to find the first non-repeating character in a string
• Create a hashmap to store character frequencies

Q2. Explain the difference between a stack and a queue . Provide an example of when you would use each?
Ans. 
A stack is a data structure that follows the Last In First Out (LIFO) principle, while a queue follows the First In First Out (FIFO) principle.
• Stack: Last In First Out (LIFO), used for function calls, undo operations.

• Queue: First In First Out (FIFO), used for printing tasks, message queues.

Q1. How do you handle debugging in your code?
Ans. 
I use print statements, logging, and debugging tools to identify and fix issues in my code.
• I start by reviewing the code and understanding the logic behind it.

• I use print statements to check the values of variables at different points in the code.

• I utilize logging to track the flow of the program and identify any errors.

• I use debugging tools like breakpoints and step-through debugging to pinpoint the exact location of ...read more

Q3. What is the difference between functional and object-oriented programming?
Ans. 
Functional programming focuses on functions and immutability, while object-oriented programming focuses on objects and encapsulation.
• Functional programming uses pure functions that do not have side effects.

• Object-oriented programming uses objects that encapsulate data and behavior.

• In functional programming, data is immutable and functions are first-class citizens.

• In object-oriented programming, objects can have state a...read more
