Quick win: shout it

Apex basics · 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

toUpperCase() returns a new copy of the text in capital letters. The original is not changed — use the result.

String name = 'ada';
String loud = name.toUpperCase();

loud is ADA. toLowerCase() works the same way but goes the other direction. For the drill, chain the result with a + and a punctuation mark, then return it from your method.

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.
