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
