final, finally, and finalize are related keywords in Java with different meanings and usage.

• final is a keyword used to declare constants, variables, methods, and classes that cannot be changed or extended.

• finally is a block used in exception handling to ensure a piece of code is always executed, whether an exception is thrown or not.

The code will output 10 because the variable i is accessed through a reference of class A.

• When a subclass object is assigned to a superclass reference, the superclass reference can only access the superclass members.

• In this case, even though the object is of class B, the variable i is accessed from class A.

• Output: 10

A Java program to check if a number is prime or not.

• Create a function to check if a number is prime by iterating from 2 to the square root of the number.

• If the number is divisible by any number in that range, it is not prime.

• Handle edge cases like 0, 1, and negative numbers separately.

• Example: public static boolean isPrime(int num) { for(int i=2; i<=Math.sqrt(num); i++) { if(num % i == 0) { return false; } } return tru

Program to determine if a given year is a leap year or not

• Check if the year is divisible by 4

• If the year is divisible by 100, also check if it is divisible by 400

• If both conditions are met, it is a leap year

I used OOPS concepts in my framework for creating reusable components and maintaining code modularity.

• Used inheritance to create a base class with common functionalities shared by multiple classes

• Implemented polymorphism to allow different classes to implement the same method in their own way

• Encapsulated data and behavior within classes using access modifiers like private and public

• Utilized abstraction to hide the impl...read more
