Assignment2 (Java Basics)

Problem 1: Summation of Numbers in a Collection

Description: (Note → Use Do While to solve this problem)

Take the size of a collection of numbers and the numbers themselves

from the user. Calculate and print the summation of the numbers.

---------------------------------------------------------------------------------------------

Problem 2: Factorial of a Number

Description: (Note → Use For Loop to solve this problem)

Write a program to calculate the factorial of a given number.

Factorial (0) =1, Factorial (1) = 1

Rule Factorial (n) = n * n-1 * n-2 *……… 1

If n = 5 Factorial (5) = 5 * 4 * 3 * 2 * 1 = 120

---------------------------------------------------------------------------------------------

Problem 3: Max, Min, and Average of a Collection

Description: (Note → Use For Loop to solve this problem)

Take the size of a collection of numbers and the numbers themselves

and print the maximum, minimum, and average of the numbers.

---------------------------------------------------------------------------------------------

Problem 4: Check for Prime Number

Description: (Note → Use For Loop to solve this problem)

Take a number from the user and check if it is a prime number or not.

5 5 divisible by only 5 and 1 => prime

6 6 divisible by 1,2,3 ,6 => not prime

---------------------------------------------------------------------------------------------

Problem 5: Count Divisible and Non-Divisible Numbers

Description: (Note → Use Do While to solve this problem)

Take the size of a collection of numbers, the numbers themselves,

and a divisor from the user. Count and print how many numbers are

divisible by the divisor and how many are not. (Do not use arrays

or array List)
