How do you find the sum of the squares of a number?
Take any positive integer n and sum the squares of its digits. If you repeat this operation, eventually you’ll either end at 1 or cycle between the eight values 4, 16, 37, 58, 89, 145, 42, and 20. For example, pick n = 389. Then 3² + 8² + 9² = 9 + 64 + 81 = 154.
How do you compute the sum of the digits of an integer in Java?

How do you find the square of first n natural numbers?
The squared terms could be 2 terms, 3 terms, or ‘n’ number of terms, first n even terms or odd terms, set of natural numbers or consecutive numbers, etc….Sum of Squares of First n Odd Numbers.

How to calculate the sum of natural numbers in Java?
In this program, you’ll learn to calculate the sum of natural numbers using for loop and while loop in Java. The positive numbers 1, 2, 3… are known as natural numbers and its sum is the result of all numbers starting from 1 to the given number. For n, the sum of natural numbers is: 1 + 2 + 3 +
How do you find the sum of odd numbers in Java?
In this Java program to find the sum of odd numbers, we used for loop without the If statement. If you observe the Java code, we started i from 1 and incremented by 2 (not 1). It means for the first iteration i = 1, and for the second iteration i = 3 (not 2) so on.
How to find square of I and add to sum?
Method 1: O (N) The idea is to run a loop from 1 to n and for each i, 1 <= i <= n, find i 2 to sum. // finding square of i and add to sum. /*This code is contributed by Nikita Tiwari.*/
How to check if a number is even or not in Java?
TIP: We already explained the logic to check the number is Even or Not in Java Odd or Even Program article in Java. I suggest you refer to the same. The For loop is to iterate from 1 to maximum value (Here, number = 5). Next, we used the If condition to check whether the remainder of the number divided by 2 is not equal to 0.
