    //Let's practice calling different methods by writing our very own methods. You will write and save methods in the space below
    //that call the existing methods you see already written here.  Ready?  Let's Go!


    //Sample: Here is a public method that calls the getfavoriteColorsMethod below and prints the results to our debug log
    public static void printOutFavoriteColorsDemo() {
        List<String> favoriteColors = getFavoriteColors();
        System.debug('Here are the favorite colors: ' + favoriteColors);

    //1.  Write a public method that calls the getFavoriteColors method to get a list of favorite colors, then add
    //another color to the list before printing it to the debug log.
    //(see the sample above for an example of calling that method-You can even start by copying and pasting that method here, renaming and modifying it)

        favoriteColors.add('navy');

    }
    //2.Write a public method that calls the amIFeelingGood and prints out the returned string to the debug log.
    //You'll need to pass in a boolean variable as the argument!

    //3.  BONUS!!  If you've finished the first two, there's another private method below that will return the top 10 Accounts
    //Write a public method that calls getTopTenAccounts.  Can you loop through those accounts and change the name of those accounts with a DML Update?

    //You don't need to know exactly how the method you're calling works, we'll cover SOQL queries later, but take a look and you'll likely get the gist
    //What's important to know is that when called it will return a list of top Accounts based on revenue, returning no more than 10.
