1 Answer(s)      5 years and 6 months ago
Posted in : Java Beginners

A Java program that reads an integer value from the user and displays i) the sum of all even integers between 1 and the input value, both inclusive. ii) The sum of all odd integers between 1 and the input value both inclusive

Example: User enters 7. Sum of even integers = 2+4+6 = 12 Sum of odd integers = 1+3+5+7=16

                                sumevenNo += i;
                        } else {
                                sumoddNo += i;
                        }
