Answer to Question #275650 in Java | JSP | JSF for Adeng

Question

using SWITCH selection statement

Write a Program that will ask the user to accept 5

integers, select an arithmetic operation for odd

and even, and perform the corresponding

operation.

Enter the first number: 34

Enter the second number: 25

Enter the third number: 62

Enter the fourth number: 13

Enter the fifth number: 27

Choose which operation you want to perform:

1. Addition

2. Subtraction

Enter the operation of odd: 1

Enter the operation of even: 2

The sum of odd numbers is: 65

The difference of even numbers is: -28
