Week 5 Homework

gistfile1.txt

    //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)

	//JW: Adding additional city and printing to the debug list
	    public static void printOutCitiesForExpansionWithExtraCity() {
        List<String> cities = getCitiesForExpansion();
        cities.add('Gold Coast'); // add another city
        System.debug('Here are the printed cities: ' + cities);
    }	

    //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!
	//JW: Adding a passed variable of the cityname 

		public static void printIsTopSalesCity(String cityName) {
        Boolean result = isTopSalesCity(cityName);
        System.debug(cityName + 'a top sales city? ' + result);
    }

    //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?

	//JW:Create a public method 
	public static void renameTopTenAccounts() {
    List<Account> topAccounts = getTopTenAccounts();

    // JW Assign a variable
    Integer rank = 10;

    //JW: Loop through the accounts to rename them and reduce the rank by 1 each loop. 
    for (Account acc : topAccounts) {
        acc.Name = acc.Name + ' - TOP ' + rank;
        rank--;
    }
	//JW: Update DML and debug
    update topAccounts;
    System.debug('Updated top 10 accounts names ' + topAccounts);
}


    //4.  BONUS!! Can you write a SOQL query that will return all opportunities for toptenAccounts based on Annual Revenue 
    //Hint:  If you're stuck, look back a the code in ClassExercises, getOpenOppsForHotAccounts method
    //  Print your results in the debug log.

    public static void getOppsForTopTenAccounts() {
        // JW: Get the top 10 accounts.
        List<Account> topAccounts = getTopTenAccounts();
        
        // JW: Add the ID's of the account to a collection
        Set<Id> accountIds = new Set<Id>();
        for (Account acc : topAccounts) {
            accountIds.add(acc.Id);
        }
        
        // JW: Query all opportunities for those accounts IDs
        List<Opportunity> oppsForTopTen =
            [SELECT Id, Name, StageName, Amount, AccountId
             FROM Opportunity
             WHERE AccountId IN :accountIds];
        
        System.debug('Opportunities for top 10 accounts: ' + oppsForTopTen);
    }

Nicely done this week! Love how you ranked the accounts when you were updating the name field. Keep it up!
