1Z0-829 Practice Question: Handling Date, Time, Text, Numeric and Boolean Values
Which two of the following are valid ways to create a LocalDate representing the current date in the system's default timezone? (Choose two.)
⚠ Common exam trap
A common mix-up: candidates assume `LocalDate.from(Instant.now())` should work because both are date/time types, but they fail to recognize that `Instant` lacks timezone and date fields, causing a runtime exception, while `new LocalDate()` is a common misconception from other Java classes that have public constructors.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
LocalDate.now()
`LocalDate.now()` is the standard, straightforward method to obtain the current date in the system's default timezone, as defined in the Java Time API (JSR-310). It internally uses the system clock and the default timezone to return a `LocalDate` instance without requiring any additional parameters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
LocalDate.from(Instant.now())
Why it's wrong here
Incorrect: from() requires a TemporalAccessor with date fields; Instant does not provide date.
- ✗
new LocalDate()
Why it's wrong here
Incorrect: LocalDate has no public constructor.
- ✓
LocalDate.now()
Why this is correct
Correct: Uses the system's default timezone.
- ✗
LocalDate.ofEpochDay(System.currentTimeMillis() / (24*60*60*1000))
Why it's wrong here
Incorrect: This does not account for timezone offset and may produce wrong date near midnight.
- ✓
LocalDate.ofInstant(Instant.now(), ZoneId.systemDefault())
Why this is correct
Correct: ofInstant method was added in Java 9 and works with default zone.
