# Java Program to Find Sum of all Odd Numbers between 0 to N

Enhancing programming skills is very important no matter what language you have chosen. So, practice frequently with these simple java programs examples and excel in coding the complex logic.

## Java Program to Find Sum of all Odd Numbers between 0 to N

• Write a program in Java 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 odd 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
