Motto: Keep in mind - try to reduce memory consumption of your application!
Q1: Think about some real use-cases when a blocking queue can be used in practice. Can you give one example of implementation for a blocking queue?
Q2: In which situation a CopyOnWriteArrayList is preferred against another concurrent implementation of a list?
Q3: Reduce memory footprint for the following class:
public class MyPersonalCar {
private Boolean inService = false;
private long age = 10; // in years
private LocalDate acquisitionDate = LocalDate.of(2010, 11, 23);
}By the way, can you specify how many bytes were saved after implementing all changes suggested?
