DEV450: Programmatic Development

//--------------------------------------------------------------------------------------------

//TASK 1: Create a Hello World anonymous block.

//TODO: Write a single line to output the text "Hello World!" to the results window

System.debug('Hello World');

//--------------------------------------------------------------------------------------------

//TASK 2: Create a map of integers and check if the map contains a specific key.

//TODO: Instantiate a map called “numbers” that has an integer as keys and a string as values.

//TODO: Create a FOR loop that loops 100 times and adds the values 0 thru 99 as the key and the string value of the number as the value of the map.

//TODO: Create an IF statement that verifies that the map contains the value 35 and display the value using a System.debug statement.

map<integer, string> numbers = new map<integer, string>();{

for (Integer i = 0; i<99; i++){

numbers.put(i,String.valueof(i));

System.Debug('This map contains the value ' + i);

}

}

//TASK 3: Create a list of new accounts with unique names.

//TODO: Instantiate a list of Account data types

//TODO: Create a loop to add 20 new accounts to the list with a unique name for each account.

//TODO: Create a FOR loop to display the name of each account in your list using System.Debug.

list<account> newaccounts = new list<account>();

//TASK 4: Create a set of date data check to see if it contains a specific day.

//TODO: Instantiate a Set of Date data types called myDates.

//TODO: Create a FOR loop that adds the next 100 days to the Set starting with Today’s date.

//TODO: Create a date variable called Birthday that contains the date of your next birthday.

//TODO: Write an IF statement that tests to see if myDates contains the value of birthday.

//--------------------------------------------------------------------------------------------

Andres, that's a good point. Going back to my analogy, at the cocktail party, we have a wealth of people circulating through the room that we can talk to. Similarly, we can find a lot of Trailhead help from the community. That help might be analogous to cocktail party conversations as well: often brief and light.

Classroom teachers and the immediacy of their availability and depth of their knowledge is incredibly valuable, but I would say that recorded online courses offered by Salesforce University are also valuable despite the lack of a live instructor. I like that I can skip through those at my own pace and get just the information I most need from them while still getting the bigger picture of how things interact. And I like that those online courses are available whenever I need them most.

I applaud Salesforce for providing so many different tools for learning in many different styles because sometimes we just want nuggets of information that we pick and choose from at our own pace and sometimes we really want to be led step-by-step with a lot of guidance. Sometimes we expect to have a lot of questions and sometimes we just want to see how well we can get it on our own.
