//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; | |
} | |
