Write a Java Program to Calculate Sum of Even Numbers from 1 to N using For Loop, and While Loop with example. Any number that is divisible by 2 is an even number.
12 Ιουν 2021 · Calculate the Sum of Even Numbers Using the While Loop. The following Java code allows the user to enter a limit value. Then, this Java program finds the sum of the even numbers from 1 to the cutoff value using the If statement and the While Loop.
We can use the formula n(n+1) to find the sum of even numbers, where n is any natural number. For instance, if we have to find the sum of the first four even numbers 2, 4, 6, and 8, the value of n will be 4. i.e. sum of first four even numbers = 2 + 4 + 6 + 8 = 20. or, = 4(4+1) = 4 * 5 = 20 (n = 4)
19 Οκτ 2022 · Java Program to Find the Sum of First N Odd & Even Numbers. When any number which ends with 0,2,4,6,8 is divided by 2 that is an even number. And when any number ends with 1,3,5,7,9 is not divided by two is an odd number. Create two variables evenSum and oddSum and initialize them by 0.
In this article, you will learn how to find the Sum of even numbers in an Array using Java. Here, we first check whether an array element is an Even number or not by dividing it by 2. If the remainder is 0 then the number is an Even number. We will add all found even numbers in a loop.
17 Οκτ 2020 · int sum = 0; System.out.println("The even numbers between "+start+" and "+end+" are the following: "); for (int r = start; r <= end; r++) { if(r % 2 == 0) { sum = sum + r; System.out.println(r); } } System.out.println("the sum : "+sum);
Program/ Example -. //In Java 8 - Find sum of all even numbers between 1 to 5. int sum1 = IntStream.of(1, 2, 3, 4, 5) .filter (n -> n % 2 == 0).sum (); //n.e. 2 + 4.
