A Left Join is a type of join operation in relational databases that returns all rows from the left table and the matched rows from the right table.
Returns all rows from the left table, even if there are no matches in the right table
If there are no matches, NULL values are used for the columns from the right table
Useful for retrieving data from one table while including any matching data from another table
Concatenate two lists of strings into a single list
Use the '+' operator to concatenate two lists
Ensure both lists are arrays of strings before concatenating
Example: list1 = ['apple', 'banana'], list2 = ['orange', 'grape']
Concatenated list: ['apple', 'banana', 'orange', 'grape']

Java is a high-level programming language known for its portability, security, and object-oriented features.
Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM).
It is known for its strong security features, such as automatic memory management and built-in exception handling.
Java is an object-oriented language, allowing for modular and reusable code through classes and objects...
Collection framework is a unified architecture for representing and manipulating collections of objects in Java.
Provides interfaces (List, Set, Map) and classes (ArrayList, HashSet, HashMap) for storing and manipulating groups of objects
Includes algorithms for searching, sorting, and manipulating collections
Allows for easy iteration over collections using iterators or enhanced for loops
OOPS concepts are the four main principles of Object-Oriented Programming: Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance: Allows a class to inherit properties and behavior from another class.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Abstraction: Hiding the complex implementation details and showing only the necessary features of an object.
Polymorphism:
Streams are sequences of data that allow for efficient processing of large amounts of data in a continuous manner.
Streams are used for processing data in a continuous and efficient manner.
They allow for reading and writing data in chunks rather than all at once.
Examples include reading a file line by line, processing a live video feed, or receiving real-time data from a network connection.
A functional interface is an interface that contains only one abstract method.
Functional interfaces can have multiple default or static methods, but only one abstract method.
Functional interfaces are used in lambda expressions and method references.
Examples of functional interfaces in Java include Runnable, Callable, and Comparator.
Java 8 introduced several new features including lambda expressions, streams, and the new Date and Time API.
Lambda expressions allow for more concise code and easier parallel programming.
Streams provide a way to process collections of objects in a functional style.
The new Date and Time API offers improved date and time handling compared to the old Date and Calendar classes.

The second question required writing a reverse of a palindrome using both Java 8 streams. I was able to successfully write both and clear the first round.
Java 17 introduces sealed classes to restrict inheritance and improve code maintainability.
Sealed classes are declared using the 'sealed' keyword followed by the permitted subclasses.
Subclasses of a sealed class must be either final or sealed themselves.
Errors may occur when trying to extend a sealed class with a non-permitted subclass.
