ORM frameworks like Hibernate can be used to connect to databases
Connection string is used to specify the database connection details
A program to take user name and print 'Hello, username'
Create a variable to store the user input
Use printf or cout to print the greeting with the user input
Set is an unordered collection of unique elements while vector is an ordered collection of elements.
Set does not allow duplicates while vector can have duplicates.
Set is implemented using hash table while vector is implemented using dynamic array.
Set has faster lookup time while vector has faster iteration time.

Collection is an interface while Collections is a class
Collection is a part of Java Collections Framework while Collections is a utility class

Hash table and hash map are two names for the same data structure that stores key-value pairs.
Both use a hash function to map keys to indices in an array
Hash table is an older term, while hash map is more commonly used in modern programming languages
Java uses the term HashMap, while Python uses the term dict
Hash maps/tables have O(1) average case time complexity for insertion, deletion, and retrieval
A collection is a group of objects of the same type while collections are classes that implement data structures.
Collections are used to store, retrieve, manipulate, and communicate aggregate data.
Java.util package provides various classes for implementing collections like ArrayList, LinkedList, HashSet, etc.
Collections can be generic or non-generic, ordered or unordered, and allow duplicates or not.

I applied via Campus Placement and was interviewed before Aug 2020. There were 4 interview rounds.
Recursive functions solve problems by breaking them down into smaller subproblems, often leading to elegant solutions.
A recursive function calls itself with modified parameters.
Base case is crucial to prevent infinite recursion.
Example: Factorial function - factorial(n) = n * factorial(n-1) with base case factorial(0) = 1.
Example: Fibonacci sequence - fib(n) = fib(n-1) + fib(n-2) with base cases fib(0) = 0, fib(1) = 1.
