1Z0-829 Practice Question: Handling Date, Time, Text, Numeric and Boolean Values

Exhibit

Refer to the exhibit.

Locale locale = new Locale("en", "US");
NumberFormat nf = NumberFormat.getPercentInstance(locale);
nf.setMinimumFractionDigits(2);
System.out.println(nf.format(0.125));

Given the exhibit, what is the output?

⚠ Common exam trap

The trap here is that candidates often forget `NumberFormat.getPercentInstance()` automatically multiplies the value by 100 and uses two decimal places by default, leading them to expect the raw decimal or a single decimal place.

Correct answer & explanation

✓

12.50%

(12.50%) because the code uses `NumberFormat.getPercentInstance()` which formats a decimal value as a percentage by multiplying it by 100 and appending a '%' sign. The input value 0.125 is formatted as '12.50%' with two decimal places by default.
