Quick win: make initials

Write Apex · Beginner · 5 min · Runs in your Salesforce Developer org · Free

Scenario. An avatar shows two letters when a Contact has no photo.

Take the first letter of two names, make them capitals and join them.

What you will learn

Text has built-in methods. left(1) gives the first character and toUpperCase() makes it a capital. You can chain them.

String first = 'jane';
String initial = first.left(1).toUpperCase();

initial is J. Do it for both names and join them with +.

The task

Write a method initials(String first, String last) that returns both initials as capitals, with nothing between them.

Examples:

• initials('jane', 'doe') → JD
• initials('Ana', 'Silva') → AS

Requirements:

1. Take the first character of each name with left(1).
2. Make each one a capital with toUpperCase().
3. Join the two with + and return the result.

Starter code

String initials(String first, String last) {
    return null;
}

System.debug(initials('jane', 'doe'));
System.debug(initials('Ana', 'Silva'));

When it passes

`initials` returns the two capital initials for every pair of names the grader tries.
