Here is a java program to find the sum of all odd numbers between 0 to N using loop.
Algorithm to find sum of all odd numbers between 1 to N
- Take N as input from user and store it in an integer variable.
- Using for loop, iterate from 0 to N.
- For every number i, check whether it is an odd number or not. if(i%2 == 1) then i is odd number else even.
- Add all even numbers in a sum variable.
Java program to calculate sum of odd numbers
package com.tcc.java.programs;
import java.util.*;
public class OddNumberSum {
public static void main(String args[]) {
int N, i, sum = 0;
Scanner in = new Scanner(System.in);
System.out.println("Enter a number");
N = in.nextInt();
for(i = 0; i <= N; i++){
if((i%2) == 1){
sum += i;
}
}
System.out.print("Sum of all odd numbers
between 0 to " + N + " = " + sum);
}
}
Output
Enter a number 10 Sum of all odd numbers between 0 to 10 = 25
