Question

Write a complete program that does the following:

accepts a positive integer from a user

if the integer is negative, the program should print "The number entered was negative."

if the integer is 0, the program should print "The number entered was zero."

if the integer is positive, the program should

use a loop to calculate the sum of all the odd integers from zero to the integer the user entered and

print "The sum from 0 to " followed by the integer entered, followed by " is " and followed by the calculated sum. The following could be possible outputs from your program:

The sum from all the odd integers from 0 to 5 is 9

or

The sum from all the odd integers from 0 to 8 is 16

Explanation / Answer

import java.util.Scanner;

public class Oddsum {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

//taking input from the user

System.out.print("Enter a Integer :");

int n=sc.nextInt();

//if it less than zero

if(n<0) System.out.println("The number entered was negative.");

//if it is equal to zero

else if(n==0) System.out.println("The number entered was zero.");

//if it is positive number

else{

//calculating oddsum

int oddSum=0;

for(int i=0;i<=n;i++){

if(i%2!=0) oddSum+=i;

}

System.out.println("The sum from all the odd integers from 0 to "+n+" is "+oddSum);

}

}

}
