20 Σεπ 2012 · while (num >= 0) // sentinel num of 0 to terminate loop. {. if (num % 2 == 0) {. count++; sum += num; System.out.println("The sum so far is " + sum); System.out.print("Enter an integer (0 to quit): "); num = scan.nextInt(); } else if (num % 2 != 0) {.
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.
Java Program to find sum of all even numbers between 1 to n. import java.util.*; public class Main { public static void main(String args[]) { Scanner sc = new Scanner(System.in); int start = 1; System.out.println("Ender Number till you want Even number sum : "); int end = sc.nextInt(); int sum = 0; while(start<=end) { if(start%2 == 0) { .
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.
21 Απρ 2024 · In Java, to find the sum of all even numbers within a given range, we can use loop concepts such as while loops or for loops. In this article, we focus on learning through examples, detailed logic, and program explanations for better understanding.
17 Ιουλ 2022 · Sum of first n even numbers = n * (n + 1). Proof: Sum of first n terms of an A.P.(Arithmetic Progression) = (n/2) * [2*a + (n-1)*d].....(i) where, a is the first term of the series and d is the difference between the adjacent terms of the series.
