    //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)
	// A method signature is a collection of 5 pieces of information:
	// public or private
	// static or (not) 
	// it's return type
	// it's name
	// it's parameters.
	// 
	// tasteTheRainbow();
    public static void tasteTheRainbow(){
        //Accepts NO parameters
    }
    
    public static void tasteThe(String what){
        //Accepts 1 parameter 'what' of type String. 
        //tasteThe('Rainbow');
        //but not tasteThe(5);
    }
    // addion(2,2) = 4;
    public static integer addition(integer first, integer second){
        return first + second;
    }
    
    // sayHello('mickey');
    // sayHello(5);
    public static String sayHello(string name){
        return 'hello ' + name;
    }

    //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!
    //
    public static void callAmIFeelingGood(){
        system.debug(amIFeelingGood(true));
    }


    //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?
 
    public static void SuperGirlNeedsADog(){
        List<Account> top10Accounts = getTopTenAccounts();
        for(Account anything : top10Accounts){
            anything.name = anything.name + ' - Awesomesauce';
            // should you ever do
            // update anything;
            system.debug(anything.name); // one at a time
        }
        update top10Accounts;
        // does system.debug(top10Accounts); // all of them at once.
    }
    
    // SuperGirlNeedsADog(); // no parameters 

    //no arguments taken, will return the same thing every time
    private static List<String> getFavoriteColors() {
        List<String> colorResponses = new List<String>();

        colorResponses.add('Red');
        colorResponses.add('Yellow');
        colorResponses.add('Blue');

        //this is the line that sends our final product out to whatever method called this one
        return colorResponses;
    }


    //takes a boolean argument and returns a string, based on that input
    private static String amIFeelingGood(Boolean feelingGood) {
        if (feelingGood == true) {
            return 'Heck Yes!  You are RAD!';
        } else {
            return 'Sorry to hear it.  Nothing like writing some code to cheer you up!!';
        }
    }


    //This method will give you the top ten account records, based on Annual Revenue
    //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.
    private static List<Account> getTopTenAccounts() {

        List<Account> topAccounts =
            [SELECT Id, Name, AnnualRevenue FROM Account WHERE AnnualRevenue != NULL AND AnnualRevenue != 0
            ORDER BY AnnualRevenue DESC LIMIT 10];
        return topAccounts;
