    Default Extracting letters as variables

    I am making a program where the user enters a country and the population onto one line and then it will display the country and the population in one line and I have got that part to work

    I need to extract the name of the country and the population in millions as variables and then have the program change the variables so the first letter of the country will be a capital letter and the population in millions as the display output. like if I put in canada 32, the display will show Canada 32milion
    I know I have to use indexof and substring methods but I have no idea where to start, any help would be appreciated

    How would you do this by hand? Pretend you have a friend who has no idea how to read. What steps would you tell him to accomplish your goal?

    When you have those steps written out in English, you'll have an algorithm that should be pretty easy to convert to code.

    I would have a look at the API docs for String here. I've done this with substring and replaceFirst as a quick job but you might be able to find a better way.
