A scheduling service stores user-entered local appointment times and must convert one to the equivalent instant in UTC. The developer has:
LocalDateTime ldt = LocalDateTime.of(2024, 3, 10, 2, 30); ZoneId zone = ZoneId.of("America/New_York");
Which expression produces the correct ZonedDateTime for this local time?
A payroll system stores employee salaries as BigDecimal. A developer writes:
BigDecimal bd = new BigDecimal(0.1); System.out.println(bd);
What is printed?

What is the result of executing the following code snippet?
BigDecimal d1 = new BigDecimal("1.00"); BigDecimal d2 = new BigDecimal("1.0"); System.out.println(d1.equals(d2));
A retail application applies a 5% sales tax to a price stored as a BigDecimal. The developer writes:
BigDecimal price = new BigDecimal("19.99"); BigDecimal taxRate = new BigDecimal("0.05"); BigDecimal tax = price.multiply(taxRate);
What is the value of tax.toString()?
A reporting module formats durations for a dashboard. The developer writes:
Duration d = Duration.ofMinutes(90); System.out.println(d.toMinutes() + ":" + d.toMinutesPart());
What is printed?
A developer writes:
var d = LocalDate.of(2023, 2, 29);
System.out.println(d);
What is the result?
