Write a java program that finds the sum of all even numbers between 1 and 55.

Also what modification would you do to the program if you wanted the sum of all odd numbers between 1 and 55

For sum of even Number:

public class even{

public static void main (String []args) {

int sum = 0;

for (int i=1; i<=55; i++) {

if (i%2==0) {

sum = sum + i;

}

}

System. out. println (sum);

}

}

Modification for sum of odd:

change the condition of if statement:

i%2==1 instead of i%2==0

Explanation:

create the main function and declare the variable with zero.

Then, take a for loop for traversing the number from 1 from 55.

Inside the for loop, if statement check the condition for even number

A number is even if number divide by 2 and give zero reminder.

so, number%2==0 it is the condition for even number.

then add the even number until condition TRUE.

and finally print the result.

Modification for sum of odd number:

A number is odd, if number divide by 2 and give one reminder.

it means, number%2==1 it is the condition for odd number.

just change the if condition with above.
