Need help with While Loop
I got a problem with this one, hope you guys can help me. I've just learned Java few weeks.
Write a program segment that reads a natural number n (n>=1) from keyboard, then
calculates and displays the sum of all odd numbers from 1 to n. Use the while loop to
validate input, if the number is smaller than 1, display an error message and the user
can try again.
Please enter a natural number greater than 1: -1
Invalid value. Please enter a natural number greater than 1: 9
Sum of odd from 1 to 9 is: 25
Thanks in advanced.
