In particular, they can provide a great deal of flexibility about which objects are created, how those objects are created, and how they are initialized. Instant Class. In such a system streaming data processing accounts for the “speed layer”, providing a real-time view of events. The only obligation is that for any objects o1 and o2 then if o1.equals(o2) is true then o1.hashCode() == o2.hashCode() is true.. What are some real-time examples Abstraction in Java? In the past, you had to write code in a language designed for real-time applications and use dedicated, special-purpose hardware to run them on. A computation that is performed at the wrong time—either too early or too late—is considered to be wrong, even if the computed numbers are exactly right. In this page you will see the common java related problems you face during your day to day activity. These systems are used to protect humans from injury or danger.
