Question

What should you do if you want the user to pass numbers as command line arguments?

First read them as string and then parse them

declare the main method with an integer array instead of a String array

Don't use double quotes around the numbers. This way they will be read in as numbers

Answer 1

First read them as string and then parse them:

we need to read it as Strings because main method designed such way that it will accept the strings as parameters

if we change the main method than the passed parameters will not reach the actual main method

so only option we have is to accept it as string and parse to int later
