Drills › Write Apex

Quick win: shout it

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

Scenario. A banner shows the team's slogan in capitals.

Turn text into capitals and add an exclamation mark.

What you will learn

toLowerCase() returns a new copy of the text in small letters. The original is not changed, so use the result.

String quietCopy(String text) {
    return text.toLowerCase() + '.';
}

quietCopy('Hi') gives hi.. toUpperCase() works the same way but goes the other direction.

The task

Write a method shout(String text) that returns the text in capitals with ! on the end.

Examples:

• shout('hi') → HI!
• shout('Apex') → APEX!

Requirements:

1. Use toUpperCase() on the input.
2. Add ! with +.
3. Keep the method's name and its String input.

Starter code

String shout(String text) {
    return null;
}

System.debug(shout('hi'));
System.debug(shout('Apex'));

When it passes

`shout` returns the input in capitals followed by `!` for every text the grader tries.
