What is inheritance, describe polymorphism, Tell me some Java 8 features, how stack works, differentiate between stack and queue considering their working, describe enhanced for loop in java, differentiate between interface and class, what is abstract class, explain encapsulation in real world scenario, write a program in java to print fibbonaci series, what is a tower of hanoi problem, so on..

Question

Accepted Answer

Inheritance is a mechanism in which a new class inherits properties and behaviors from an existing class. Polymorphism allows objects of different classes to be treated as objects of a common superclass.

Java 8 features include lambda expressions, functional interfaces, streams, and default methods.
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.
Enhanced for loop in Java is used to iterate over elements in an array or collection without using an index variable.
Interface in Java is a blueprint of a class that contains only abstract methods, while a class can have both abstract and concrete methods.
Abstract class in Java is a class that cannot be instantiated and may contain abstract methods that must be implemented by its subclasses.
Encapsulation in real-world scenario can be seen in a bank account where the account balance is kept private and can only be accessed through methods like deposit and withdraw.
Tower of Hanoi problem is a mathematical puzzle that involves moving a stack of disks from one rod to another, following specific rules.
