- //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 getCitiesForExpansion below and prints the results to our debug log
- public static void printOutCitiesForExpansionDemo() {
- //The code on the left of the equals sign instantiates a list of Strings, the code on the right side calls our method and returns a list of cities
- //the equals sign assigns the returned value, to the list we created
- List<String> cities = getCitiesForExpansion();
- System.debug('Here are the cities: ' + cities);
- }
- //1. Write a public method that calls the getCitiesForExpansion method to get a list of cities, then add
- //another city 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)
- public static void findOutCitiesForExpansionDemo() {
- //The code on the left of the equals sign instantiates a list of Strings, the code on the right side calls our method and returns a list of cities
- //the equals sign assigns the returned value, to the list we created
- List<String> kEcities = getCitiesForExpansion();
- kEcities.add('NYC');
- System.debug('Here are the cities: ' + kEcities);
- }
- //2.Write a public method that calls the isTopSalesCity method and prints out the returned boolean to the debug log.
- //You'll need to pass in a string variable that is a city name as the argument!
- public static void verifyTopSalesCity(){
- String topSalesCity = 'Houston';
- Boolean isTopCity = isTopSalesCity('inspectCity');
- System.debug(topSalesCity+ 'Is the top sales city ' + isTopCity);
- }
- //3. BONUS!! If you've finished the first two, there's another public 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 changeAccounts(String addName){
- List<Account> topTenAccounts = getTopTenAccounts();
- System.debug('Top Ten Accounts: '+ topTenAccounts);
- for(Account topAcct: topTenAccounts){
- topAcct.Name = topAcct.Name + ' ' + addName;
- }
- Update topTenAccounts;
- System.debug('Top Ten Accounts: ' + topTenAccounts);
- }
- //no arguments taken, will return the same thing every time
- public static List<String> getCitiesForExpansion() {
- List<String> cities = new List<String>();
- cities.add('Tokyo');
- cities.add('Melbourne');
- cities.add('Portland');
- //this is the line that sends our final product out to whatever method called this one
- return cities;
- }
- //takes a string argument and returns a boolean, based on that input
- public static Boolean isTopSalesCity (String cityName) {
- if (cityName=='Seattle' || cityName=='Los Angeles' || cityName=='Portland') {
- return true;
- } else {
- return false;
- }
- }
- //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.
- public 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;
- }
- }
