Program to reverse a string using Java
Use StringBuilder class to reverse the string
Convert the string to StringBuilder, call reverse() method, then convert back to string
Alternatively, use char array and swap characters from start and end
ArrayList vs LinkedList: ArrayList uses dynamic array, LinkedList uses doubly linked list. HashMap vs HashSet: HashMap stores key-value pairs, HashSet stores unique elements.
ArrayList is faster for accessing elements by index, LinkedList is faster for adding/removing elements in the middle.
HashMap allows null key and values, HashSet does not allow duplicate elements.
Example: ArrayList<String> list = new ArrayList...

String is immutable, StringBuffer is synchronized and mutable, StringBuilder is not synchronized and mutable.
String is immutable, meaning its value cannot be changed once it is created.
StringBuffer is synchronized, making it thread-safe, but slower than StringBuilder.
StringBuilder is not synchronized, making it faster than StringBuffer but not thread-safe.
Abstract classes can have both abstract and non-abstract methods, while interfaces can only have abstract methods.
Abstract classes can have constructors, interfaces cannot.
A class can implement multiple interfaces, but can only extend one abstract class.
Interfaces are used to achieve multiple inheritance in Java.
Abstract classes are used to provide a common base for subclasses to extend.

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.
OOP focuses on creating objects that interact with each other to solve a problem.
It involves concepts like classes, objects, inheritance, polymorphism, and encapsulation.
For example, in a banking system, a 'BankAccount' class can have objects like '...
Collections refer to the process of gathering and organizing items or objects into a group.
Collections can include items such as books, art, antiques, coins, stamps, etc.

Collections can be displayed in museums, galleries, private homes, or online platforms.
Some famous collections include the British Museum in London, the Louvre in Pari
List is an ordered collection of elements with duplicates allowed, while Set is an unordered collection of unique elements.
List maintains the insertion order of elements, while Set does not guarantee any specific order.
List allows duplicate elements, while Set does not allow duplicates.
Examples: List - [1, 2, 3, 1], Set - {1, 2, 3}
