Quick win: pick the larger number
Apex basics · Beginner · 5 min · Runs in your Salesforce Developer org · Free
Scenario. A report shows the higher of two quarterly totals.
Return the bigger of two numbers. Your first if.
What you will learn
if runs a block only when its test is true. Returning from inside the if ends the method, so the line after it only runs when the test was false.
if (n >= 0) {
return 'non-negative';
}
return 'negative';Apply the same pattern with two numbers: compare them, and return whichever one is larger.
The task
Write a method larger(Integer a, Integer b) that returns the bigger of the two.
Examples:
larger(3, 9)→9larger(9, 3)→9larger(4, 4)→4
Requirements:
- Use
ifto compareaandb. - When they are equal, return either one. They are the same number.
- Keep the method's name and its two Integer inputs.
Starter code
Integer larger(Integer a, Integer b) {
return null;
}
System.debug('3 or 9: ' + larger(3, 9));
System.debug('9 or 3: ' + larger(9, 3));
When it passes
`larger` returns the bigger number for every pair the grader tries, including equal and negative numbers.
