JAVA

Let's use this String array[] parameter in our program to pass information into our main() method and use it to do some computations.

pseudocode

pass in an operation and then perform that operation on all successive numbers passed into our main() method application.

Example 1 command line execution of our program:

>java MyCommandLine + 1 2 3 4 5

output would be:

1 + 2 + 3 + 4 + 5 = 15

example 2:

>java MyCommandLine - 15 2 3

output would be:

15 - 2 - 3 = 10

example 3:

>java MyCommandLine * 3 2 5

output would be:

3 * 2 * 5 = 30

Modularize your logic: create 1 or more method(s) to process our String array[].

use a Switch statement on the operation (first element in the array[]) + * -
